    Victron CYRIX-LI-CHARGE 12/24-120A Intelligent Charge Relay Cyrix LI Charge [CYR010120430]

    CYRIX-LI-CHARGE 12/24-120A Intelligent Charge Relay Cyrix LI ChargeThe Cyrix Battery Combiner is a microprocessor-controlled heavy duty relay that automatically connects batteries in parallel when one of them has reached a pre-set voltage (indicating that the battery is being charged) and disconnects when the voltage decreases below float level (indicating that one or more batteries are being discharged). Cyrix Battery Combiners are an excellent replacement for diode isolators. The main feature is that there is virtually no voltage loss so that the output voltage of alternators or battery chargers does not need to be increased.Please contact your dealer for any returns, repairs or support issues related to this product.

    Mastervolt Charge Mate Pro Lithium 40 [83304004]

    Charge Mate Pro Lithium 40Current limited electronic charge relay with high efficiency and reverse current protectionA secondary battery on board requires a dedicated charging solution. The Charge Mate Pro charging relay 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 consists 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.Applications:Leisure and professional marine and mobile applications. An effective solution for high power demand on board and/or the need for prioritized or current limited charging.Features: Electronic charge coupling with very low voltage drop. Makes effective dual charging possible. Suitable for charging from Lithium starter batteries to AGM/GEL/Lithium service batteries. Charge current secondary battery limited to 40 A. High system reliability by prioritizing charging of the main battery. Unidirectional which blocks return current under all circumstances. Prevents power dips in 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.

  • Sale -37% BEP Digital Voltage Sensing Relay DVSR - 12/24V [710-140A]

    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.
