    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.

  • Sale -47% BEP Pro Installer 400a EZ-Mount Dual Bank Control Battery Switch - MC10 [772-DBC-EZ] BEP Pro Installer 400a EZ-Mount Dual Bank Control Battery Switch - MC10 [772-DBC-EZ]

    BEP Pro Installer 400a EZ-Mount Dual Bank Control Battery Switch - MC10 [772-DBC-EZ]

    Pro Installer 400A EZ-Mount Dual Bank Control Battery Switch - MC10Another addition to our multi award winning Pro Installer EZ Mount range, the innovative Dual Bank Control switch is like 3 switches in one, House, Start, and Emergency Parallel. Offering easy intuitive control for the boater, the Dual Bank Control switch features a unique isolated-On position which allows use of house loads and VHF radio if the engine needs to be electrically isolated, or allows the engine to be isolated during servicing while still providing power to house loads (for lighting, stereo, fridge etc). For boats or vehicles with single Engine and House battery bank, Dual Bank Control allows the use of optimized battery banks for their respective loads; an appropriately sized deep cycle bank for House loads, and thin plate starting batteries for the Engine. Further, sensitive electronics are isolated from starter motor induced voltage spikes because House and Engine loads are separated during normal operation, unlike Selector battery switches. As easy as 1, 2, 3, these revolutionary EZ Mount battery switches allow you to wire from the front for the easiest surface mounting. With their shared interconnection height, EZ-Mount battery switches "cluster" directly with the Pro Installer Busbar Range, resulting in the fastest, most compact installations.
