HPSB 2512B v.1.0/VII

HPSB 13,8V/2A/7Ah Buffer, switch mode power supply unit

CODE:

TYPE:

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=2A + 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 7Ah/12V battery. A micro

switch indicates door opening (front cover).

During normal operation, the total current drawn by the equipment may not exceed I = 2 A .

Maximum battery charging current: 0.5 A .

Total device current + battery: 2.5 A max .
