1.1 General description
A buffer PSU is intended for an uninterrupted supply to devices requiring stabilized voltage of
24 V DC
(+/-15%).
The PSU provides voltage of
27,6V DC
with current capacity
I=1,5A + 0,16A 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=1,5A.
Maximum battery charging current: 0,16 A. Total device c battery: 1,66 A max.
