Mastervolt Charge Mate Pro 40 Electronics Relay - 83304002

The Mastervolt Charge Mate Pro 40 Electronics Relay is a current limited electronic charge relay with high efficiency and reverse current protection. It is designed to provide a dedicated charging solution for a secondary battery on board.

The Charge Mate Pro effectively distributes the charger or alternator current between two battery banks, such as a starter and a service battery. It connects both batteries during charging and keeps them isolated when discharging, reducing the risk of a flat starter battery.

This charge relay offers an advantage over mechanical charge relays by limiting the charge current to the second battery. The primary battery, like a starter battery, is 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.

An example of a marine application for the Charge Mate Pro is the connection of a bow thruster battery to a service battery. It ensures that the service battery is always charged with priority and blocks the return current from the bow thruster battery, guaranteeing that the bow battery remains charged. The current limiting feature also prevents power dips in 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.
