www.pulsar.pl ROUPS48V RACK POWER 1. Technical description. 1.1. General 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 5A.

www.pulsar.pl ROUPS48V RACK POWER 2.2. Installation procedure. 1. Before installation, cut off the voltage in the 230V power-supply circuit. 2. Mount the power supply in a RACK 19" cabinet as shown below: - Mount M6 cage nuts - Secure the enclosure with 4xM4 screws 3. Connect the receivers’ cables to the terminals AUX. 4. If needed, the following technical connections can be made: - ALARM – technical output of collective failure 5.
