1. Technical description.
1.1 General description
A buffer PSU is intended for an uninterrupted supply to devices requiring stabilized voltage of
12V DC
(+/-15%).
The PSU provides voltage of
13,8V DC
with current capacity
I=3A + 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=3A.
Maximum battery charging current: 0,5A. Total device c battery: 3,5A max
