DESCRIPTION

A buffer PSU intended for uninterrupted supply to devices that require stabilised voltage of 12V DC (+/-15%).
The PSU provides voltage of U=13,8V 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 = 3A*.
Maximum battery charging current: 0.5 A*.
Total device current + battery: 3.5 A max*.
