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 = 1A + 0,3A 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=1 A. The maximum battery
charging current is 0,3 A. The total current of the receivers + battery is max. 1,3 A.
