1. Technical description.
1.1 General description.
A buffer PSU is designed for uninterrupted supply of devices requiring stabilized voltage of
12V DC (+/-
15%).
The PSU supplies voltage of
U=13,8V DC
and total current capacity of
:
1. Output current 2A + 0,2A battery charging
2. Output current 1,7A + 0,5A battery charging
Total c battery is max. 2,2A
In case of mains power loss, the unit will instantly switch to battery operation. The PSU is enclosed in a
metal casing (color RAL 9003) with battery housing for 7Ah/12V batteries. The enclosure is fitted with a micro
switch indicating door opening (front cover) and the detachment from the wall.
