1. Technical description.
1.1 General description.
A buffer PSU intended for uninterrupted supply to devices that require stabilised voltage of 12 V DC (+/-
15%). The PSU provides voltage of U=13,8 V DC with output current of I=3A + 0,5A for battery charging. 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).
During normal operation, the total current drawn by the equipment may not exceed I = 3 A;
Maximum battery charging current: 0.5 A. Total device c battery: 3.5 A max.
