  • BEP Digital Voltage Sensing Relay DVSR - 12/24V [710-140A]

    BEP Marine BEP Digital Voltage Sensing Relay DVSR - 12/24V [710-140A]

    Digtal Voltage Sensing Relay (DVSR) - 12/24VThe Digital Voltage Sensing Relay (DVSR) allows the charging of a second battery bank from any single charging source. When the voltage on the charged bank rises sufficiently, the DVSR engages allowing the 2nd battery bank to charge. When charging stops and voltage falls, the DVSR automatically isolates the battery banks, ensuring that engine start batteries are kept fully charged. Digital circuitry provides superior reliability and extremely low power consumption. Digital enhancements have introduced remote sensing circuitry that allows an optional connection from the ignition switch to provide the same functionality as single sense VSR and zero power consumption when engine is off. Another benefit is a zero stand by current draw when remote sensing circuit is utilized with a storage mode switch fitted (switch in open position).Features: Safely charge two or more independent battery banks from one charge source such as an alternator or battery charger Charges engine starting batteries before combining auxiliary bank for charging Protects start batteries from becoming flattened by domestic loads Isolates electronics from harmful electrical surges from starter motors Simple to install 3 wire connection leaves alternator wiring intact No volt drop vs diode isolators Ignition protected Surface or panel mountable Replaces previous models 710-125A and 710-125A-DS Multi voltage, auto selects between 12 and 24V DC operation Digital circuits provide very low power consumption and enhanced performance Remote status LED output option WARNING: This product can expose you to chemicals including di(2-ethylhexyl)phthalate (dehp) which is known to the State of California to cause cancer, birth defects or other reproductive harm.

  • Victron Smart BatteryProtect - 220AMP - 6-35 VDC - Bluetooth Capable [BPR122022000] Victron Smart BatteryProtect - 220AMP - 6-35 VDC - Bluetooth Capable [BPR122022000]

    Victron Energy Victron Smart BatteryProtect - 220AMP - 6-35 VDC - Bluetooth Capable [BPR122022000]

    Smart BatteryProtect - 220AMP - 6-35 VDC - Bluetooth CapableFeatures: Protects the battery against excessive discharge and can be used as a system on/off switch The Smart BatteryProtect disconnects the battery from non-essential loads before it is completely discharged (which would damage the battery) or before it has insufficient power left to crank the engine. The on/off input can be used as a system on/off switch.  12/24V auto ranging The Smart BatteryProtect automatically detects system voltage one time only.  Bluetooth: programming made easy When using Bluetooth to program the Smart BatteryProtect any required engage/disengage levels can be set. Alternatively, one of nine predefined engage/disengage levels can be set with the programming pin (see manual). If required, Bluetooth can be disabled.  A special setting for Li-ion batteries In this mode the BatteryProtect can be controlled by the VE.Bus BMS. Note: the BatteryProtect can also be used as a charge interrupter in between a battery charger and a Li-ion battery. See connection diagram in the manual. Ultra-low current consumption This is important in case of Li-ion batteries, especially after low voltage shutdown. Please see our Li-ion battery datasheet and the VE.Bus BMS manual for more information.  Over voltage protection To prevent damage to sensitive loads due to over voltage, the load is disconnected whenever the DC voltage exceeds 16.3V respectively 32.6V.  Ignition proof No relays but MOSFET switches, and therefore no sparks.  Delayed alarm output The alarm output is activated if the battery voltage drops below the preset disconnect level during more than 12 seconds. Starting the engine will therefore not activate the alarm. The alarm output is a short circuit proof open collector output to the negative (minus) rail, max. current 50 mA. The alarm output is typically used to activate a buzzer, LED or relay.  Delayed load disconnect and delayed reconnect The load will be disconnected 90 seconds after the battery voltage drops below the preset level. If the battery voltage increases again to the connect threshold within this time period (after the engine has been started for example), the load will not be disconnected. The load will be reconnected 30 seconds after the battery voltage has increased to more than the preset reconnect voltage.

  • Victron Lynx Smart BMS 1000 Battery Management System f/Lithium Smart Batteries [LYN034170210]

    Victron Energy Victron Lynx Smart BMS 1000 Battery Management System f/Lithium Smart Batteries [LYN034170210]

    Lynx Smart BMS 1000 Battery Management System for Lithium Smart BatteriesThe Lynx Smart BMS is a dedicated Battery Management System (BMS) for the Victron Lithium Battery Smart batteries. These batteries are Lithium Iron Phosphate (LiFePO4) batteries and are available in 12.8 V or 25.6 V in various capacities. They can be connected in series, parallel, and series/parallel so that a battery bank can be built for system voltages of 12V, 24 V, or 48 V. The maximum number of batteries in one system is 20, which results in a maximum energy storage of 84 kWh in a 12 V and up to 102 kWh in a 24 V1) and 48 V1) system.Out of the various available BMSes, the Lynx Smart BMS is the most feature-rich and complete option and integrates seamlessly into the Lynx Distributor system. This model is a 1000 A (M10) version.Built-in 1000 A ContactorThe contactor acts as a secondary safety system to protect the battery in case the primary controls (ATC, ATD, and/or DVCC) fail to disable loads and/or chargers when required and is also suitable as a remote controllable main system switch.Pre-charge CircuitIn addition to the contactor, a built-in pre-charge circuit prevents high inrush currents when connecting a capacitive load such as a MultiPlus/Quattro or other inverter, eliminating the need for external pre-charging.Monitoring and ControlMonitor and control the BMS via Bluetooth using the VictronConnect App or a GX device such as a Cerbo GX and the VRM Portal. A built-in battery monitor that operates similarly as the other Victron Energy battery monitors, provides data such as state of charge, voltage, current, historical data, status info, and more in real-time and with instant readout even without the need to connect to the BMS, allowing diagnostic at a glance.DVCC closed Loop Control as Well as ATC/ATD ContactsCompatible Victron inverters/chargers and solar chargers are automatically controlled via a connected GX device and DVCC. The ATC/ATD contacts can be used to control other chargers and loads that have a remote on/off port.Programmable RelayThe relay can be used either as an alarm relay (combined with the pre-alarm) or to control an alternator via its external regulator (ignition cable). In Alternator ATC mode, the relay will only activate when the contactor is closed. Alternator ATC contact of the alternator opens first and then with a delay of 2 seconds the contactor. These 2 seconds ensure that the alternator is switched off before the battery is disconnected from the system.AUX TerminalThe advantage of the onboard auxiliary power supply (1.1 A @ system voltage) is to provide power to specific loads (i.e. a GX device) after the BMS has shut down the loads in the event of a low cell voltage event. If no charge voltage is detected within 5 minutes, the BMS, including the AUX connection switches off.VE.Can and NMEA 2000 Data CommunicationVE.Can allows for easy connection (standard RJ45 network cable) and communication with a GX device. Since the CANbus protocol is based on NMEA 2000 (and J1939), it is easy to integrate into a marine network and feed a marine MFD with data (requires a VE.Can to NMEA 2000 micro-C male cable).Lynx Distributor Fuse MonitoringRead out the fuse status and receive an alarm in case a fuse is blown. The Lynx Smart BMS monitors up to 4 connected Lynx Distributors and their fuses via VictronConnect or a GX device 1) To reduce the required balancing time, we recommend using as many different batteries in series as possible for the application. 24 V systems are best built using 24 V batteries, and a 48 V system.This System Contains the Following Components: Lynx Distributor with 2 fused paralleled lithium-ion smart batteries. Lynx Smart BMS with BMS, contactor, and battery monitor A second Lynx distributor provides fused connections for inverter/charger(s), loads and chargers (additional modules can be added if more connections are needed) A Cerbo GX (or other GX device) to read out the Lynx Smart BMS and Lynx Distributor data.

  • Mastervolt Charge Mate Pro 40 - Electronics Charge Relay [83304002] Mastervolt Charge Mate Pro 40 - Electronics Charge Relay [83304002]

    Mastervolt Mastervolt Charge Mate Pro 40 - Electronics Charge Relay [83304002]

    Charge Mate Pro 40 - Electronics Charge RelayCurrent limited electronic charge relay with high efficiency and reverse current protectionA secondary battery on board requires a dedicated charging solution. The Charge Mate Pro makes it possible to distribute the charger or alternator current effectively between two battery banks such as a starter and a service battery. The Charge Mate Pro connects both batteries during charging and keeps them isolated when discharging. This significantly reduces the risk of a flat starter battery for example.The Charge Mate Pro offers an additional advantage over mechanical charge relays, by limiting the charge current to the second battery. The primary battery, like a starter battery, is therefore charged with priority. The return current is automatically blocked even when the secondary battery has a higher voltage. An emergency start function is possible by connecting an optional bypass switch to the Charge Master Pro.A marine application example is the connection of a bow thruster battery to a service battery. The Charge Mate Pro ensures that the service battery is always charged with priority. The blocking of the return current from the bow thruster battery guarantees that the bow battery remains charged while the current limiting also prevents power dips of the onboard electrical network.The Charge Mate Pro series consist of a 40 Amp and a 90 Amp version, both suitable for charger or alternator applications.Charge Mate Pro: for controlled charging from a single source.ApplicationsLeisure and professional marine and mobile applications. An effective solution for high power demand on board and/or the need of prioritised or current limited charging.Features Electronic charge coupling with very low voltage drop Makes effective dual charging possible Suitable for all battery types, including Lithium Ion Charge current secondary battery limited to 40 A High system reliability by prioritised charging of the main battery Unidirectional which blocks return current under all circumstances Prevents power dips of the onboard electrical network Suitable for all kinds of chargers and alternators Monitoring with LED status indication IP65 electronics in a corrosion resistant casing with aluminum heat sinks Fast and easy installation General specifications Remote switch functions:  on, off, auto, start assist Monitoring: LED (warnings and status indication) Output current: limited to 40 A Number of battery outlets: 2 Input voltage range: 9-32 V Parallel configuration: yes Battery voltage: automatic 12/24 V detection Dimensions, hxwxd: 157 x 140 x 80 mm / 6.2" x 5.5" x 3.1" Weight: 0.88 kg / 1.9 lb Approvals: CE Technical specifications Connection possibilities: 3 x fast-on connectors (switch, ground and status) o switch: for an optional single pole ON-OFF-ON switch for remote operation o status: for an optional LED indicator Power consumption: switch open: < 1 mA at 12/24 V DC Battery types: all types (Lithium Ion protection via Multi purpose contact, product code 77030500) Switch on voltage: 13.5 V (12 V) / 27 V (24 V) Switch on delay: 5 sec.

Ignition proof No relays but MOSFET switches, and therefore no sparks. Delayed alarm output The alarm output is activated if the battery voltage drops below the preset disconnect level during more than 12 seconds. Starting the engine will therefore not activate the alarm. The alarm output is a short circuit proof open collector output to the negative (minus) rail, max. current 50 mA. The alarm output is typically used to activate a buzzer, LED or relay. Delayed load disconnect and delayed reconnect The load will be disconnected 90 seconds after the alarm has been activated. If the battery voltage increases again to the connect threshold within this time period (after the engine has been started for example), the load will not be disconnected. The load will be reconnected 30 seconds after the battery voltage has increased to more than the preset reconnect voltage.

  • Victron SmartSolar MPPT 150/60-TR Solar Charge Controller - UL Approved [SCC115060211]

    Victron Energy Victron SmartSolar MPPT 150/60-TR Solar Charge Controller - UL Approved [SCC115060211]

    SmartSolar MPPT 150/60-TRThe Victron SmartSolar MPPT 150/60 Solar Charge Controller is Bluetooth accessible via either built-in Bluetooth or the Victron Energy Bluetooth dongle. The VictronConnect app is available for free on both iOS and Android. This app allows you to view plenty of parameters: battery voltage, solar history, load output, flexible battery charge algorithms, plus day/night timing and light dimming options. These solar charge controllers will gather energy from your solar panels fast and efficiently. Ultra-fast Maximum Power Point Tracking (MPPT) Especially in the case of a clouded sky, when light intensity is changing continuously, an ultra-fast MPPT controller will improve energy harvest by up to 30% compared to PWM charge controllers and by up to 10% compared to slower MPPT controllers. Load output Over-discharge of the battery can be prevented by connecting all loads to the load output. The load output will disconnect the load when the battery has been discharged to a pre-set voltage. Alternatively, an intelligent battery management algorithm can be chosen: see Battery Life. The load output is short circuit proof. Some loads (especially inverters) can best be connected directly to the battery, and the inverter remote control is connected to the load output. A special interface cable may be needed, please see the manual Battery Life: intelligent battery management When a solar charge controller is not able to recharge the battery to its full capacity within one day, the result is often that the battery will continually be cycled between a ‘partially charged’ state and the ‘end of discharge’ state. This mode of operation (no regular full recharge) will destroy a lead-acid battery within weeks or months. MPPT: Ultra Fast Maximum Power Point TrackingBy constantly monitoring the voltage and current output of your solar (PV) panels, MPPT technology ensures that every drop of available power is rinsed out of your panels, and harvested for storage. The advantage of this is most noticeable when the sky is partially clouded, and light intensity is constantly changing.Please contact your dealer for any returns, repairs or support issues related to this product.
