DESCRIPTION
A buffer PSU is intended for an uninterrupted supply to devices requiring stabilised voltage of 48V DC
(+/-15%). The PSU provides voltage of U=54V DC. Current efficiency:
1. Output current 2A + 0,5A battery charge*
2. Output current 1,5A + 1A battery charge*
Total device current + battery: 2,5A 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 a 4x7Ah/12V battery. A micro switch indicates door opening (front cover).
