Charge Mate Pro 90
Current limited electronic charge relay with high efficiency and reverse current
protection
A secondary battery onboard 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 ChargeMaster 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. The Charge Mate Pro 90 ensures
a higher charge current for example when charging Lithium-Ion batteries. It is
also perfectly suitable for large automotive alternators up to 180 A and can be
used in parallel operation with a 225 Amp alternator to fulfill even higher
continuous power demands of your equipment on board.
