1. Technical description.
1.1 General description.
A buffer PSU is designed for uninterrupted supply of devices requiring stabilized voltage of
24V DC (+/-
15%).
The PSU supplies voltage of
U=27,6V DC
and total current capacity of:
1. Output current 1A (without battery)
2. Output current 0,8A + 0,2A battery charging
3. Output current 0,5A + 0,5A battery charging
Total c battery is max. 1A
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 two 7Ah/12V batteries. The enclosure is fitted with a micro
switch indicating door opening (front cover) and the detachment from the wall.
