1. Technical description.
1.1 General description.
A buffer PSU intended for uninterrupted supply to devices that require stabilised voltage of
48V DC (+/-
1V).
The PSU provides voltage of
U=48V DC
with output current of
I=1,2A
+ 0,5A for battery charging
*
.
In case
of power decay, a battery back-up is activated immediately. The power supply is constructed on the basis of a
switch mode PSU with high energy efficiency and 12/48V DC boost converter and is housed in a metal enclosure
(RAL 9003) with battery space for 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 = 1,2A
*
.
Maximum battery charging current: 0,5A.
