1. Technical description.
1.1. General description.
The buffer power supply
RUPS848T
is used for uninterrupted supply of devices requiring stabilized voltage
of
48V DC (+/- 15%).
The PSU supplies voltage of
U=54V
DC
and total current capacity of:
Output current 4A + 0,5A battery charge.
Total device c battery: 4,5A max.
In case of power decay, a battery back-up is activated immediately. The PSU is fitted with 8 outputs
protected independently with glass fuse 0,5A. The power supply is fitted with the ALARM output of collective
failure. In case of failure, relay contacts are switched automatically, which is accompanied by acoustic and optical
indication (the corresponding led goes on). The power supply construction is based on the switch mode PSU with
high energy efficiency and is located in an enclosure adapted for mounting in standard
RACK
19
” cabinets.
