1.1 General description
A buffer PSU is intended for an uninterrupted supply to devices requiring stabilized voltage of 12 V DC (+/-
15%). The PSU provides voltage of U=13,8V DC with current capacity I=2A + 0,5A battery charge. In case of
power decay, a battery back-up is activated immediately.
During normal operation, the total current drawn by the receivers may not exceed I=2A.
Maximum battery charging current: 0.5 A. Total device c battery: 2,5 A max.
