1. Technical description.
1.1 General description.
A buffer PSU is intended for an uninterrupted supply to devices requiring stabilised voltage of 12 V DC
(+/-15%). The PSU provides voltage of U=13,8 V DC. Current efficiency:
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 17Ah/12V battery. A micro switch indicates door opening (front cover).
