1. Technical description.
1.1 General description.
A buffer PSU is intended for an uninterrupted supply to devices requiring stabilised voltage of 24 V DC (+/-
15%). The PSU provides voltage of U=27,6 V DC. Current efficiency:
1. Output current 5A + 0,5A battery charge
2. Output current 3,5A + 2A battery charge
Total device c battery: 5,5A 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 two 17Ah/12V batteries. A micro switch indicates door opening (front cover).
