Charge Mate Pro Lithium 40
Current limited electronic charge relay with high efficiency and reverse current protection
A 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.
