1. Technical description.
1.1 General description.
A buffer PSU is intended for uninterrupted supply to devices that require stabilised voltage of 24 V DC (+/-
15%). The PSU provides voltage of U=27,6 V DC with output current of I=1,5A + 0,3A for battery charge. 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 7Ah/12V batteries. A micro switch indicates door opening (front cover).
During normal operation, the total current drawn by the equipment may not exceed I = 1,5 A;
Maximum battery charge current: 0.3 A. Total device c battery: 1,8 A max.
