ROUPS 54V/5A RACK mounted buffer power supply.

DESCRIPTION

The ROUPS48V buffer power supply unit is designed for uninterrupted power supply of requiring stabilized

voltage of 48V DC (+/- 15%). The PSU provides voltage of U=54V DC current efficiency max. I=4,5A + 0,5A battery

charge. In case of power decay, a battery back-up is activated immediately. The PSU output protected

independently with melting fuse 5 . 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.

AUX power supply output can be split into 8 or 16 outputs with the use of RACK fuse modules:

- the RLB8 (RACK 8x2A fuse modules)

- the RLB16 (RACK 16x1 fuse modules)
