1. Technical description
1.1 General description
The buffer PSU module is dedicated for uninterrupted supply of alarm systems devices requiring the
stabilized voltage of
12V/DC (+/-15%)
. The PSU module delivers the voltage within the range
13,8 V DC
with the
current capacity:
1. Output current 2,0A + 0,2A battery charging
2. Output current 2,0A + 0,5A battery charging
Total device c battery: 2,5A max.
In the case of power failure from prime supply, the unit is instantly switched to battery assisted operation.
Battery charging current is set at the factory to
0,5A.
