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 rec battery is max. 3,3 A.
