Product InformationStore Part Number: JAC0524-R


The Schauer JAC0524-R Charge Master is a Fully Automatic Constant Current Battery Charger. The charger features a 3-Stage charging profile that charges faster and more accurately than conventional chargers.

Japlar Schauer's 3-Stage profile starts with a Constant Current charge, followed by a Constant Voltage charge, and finishes with a Float standby mode. The float charge holds the battery at 100% ready state. The charger can be left on indefinitely without worry of undercharge or overcharging the battery.

Japlar Schaur Chargers employ Soft Start and Stop, which gradually starts and stops charger with no sudden in-rush of current. This protects both the batteries and any other circuits connected to the charger.

Stage 1: Constant Current Mode (CC)
The charger changes to constant current 5.0A. When the battery voltage reaches up to 29.2V, the charging stage changes from (CC) Constant Current to CV (Constant Voltage) mode.

Stage 2: Constant Voltage Mode (CV)
The charger holds the battery at 29.2V and the current slowly reduces. The moment the current reaches 0.5 C (C= Battery Capacity), is called the Switching Point. The Switching Point is one of the great features of this battery charger that it can adjust the current automatically according to the battery capacity. Other chargers without microprocessors are not capable to adjust the current automatically.

Stage 3: Standby Voltage Mode
The charger maintains the battery voltage at 27.0V and current slowly reduces to zero. Charger can be left connected indefinitely without harming the battery.

The JAC Series charger will act as a power supply in conjunction with a battery hook up.
