1. Technical description.

1.1. General description.

The buffer power supply is designed for uninterrupted supply of devices requiring stabilized voltage of 12 V DC (+/-15%).

The PSU supplies voltage of 13,8 V DC with current efficiency of I = 3 A + 0,3 A battery charging. In the case of mains power

failure, the unit will instantly switch to battery power. The power supply unit is protected against short-circuit, overload and

overvoltage.

During normal operation, the total current drawn by the device cannot exceed I=3 A. The maximum battery

charging current is 0,3 A. The total current of the receivers + battery is max. 3,3 A.
