The RPB45S is a universal battery protection relay; when used with a shunt, it can measure
any current. The protection thresholds and time delays are freely adjustable for each
current direction (charge and discharge), allowing it to cover all types of batteries.
The RPB45S is equipped with an isolated analog output for transmitting the current measurement.
