1. Technical description.
1.1 General description.
A buffer PSU is intended for an uninterrupted supply to devices requiring stabilised voltage of
12V DC
(+/-15%).
The PSU provides voltage of
U=13,8V DC.
Current efficiency:
1. Output current 18x0,5A + 1A battery charge
2. Output current 18x0,38A + 4A battery charge
Total device c battery: 11A max
*
.
In case of power decay, a battery back-up is activated immediately. The PSU is constructed based on the
switch mode PSU, with high energy efficiency. The PSU is housed in a metal enclosure (colour RAL 9003) which
can accommodate a 7Ah/12V battery. A micro switch indicates door opening (front cover).
