1.1 General description
A buffer PSU is intended for an uninterrupted supply to devices requiring stabilized voltage of
24V DC
(+/-15%).
The PSU provides voltage of
U=27,6V DC
with current capacity
I=1A + 0,3A 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=1A.
Maximum battery charging current: 0.3 A. Total device c battery: 1,3 A max
