1. Technical description.
1.1. General description.
The ROUPS12VR buffer power supply unit is designed for uninterrupted power supply of up to recorder
requiring stabilized voltage of 12V DC. The PSU provides voltage of U=12V DC current efficiency max. I=5A + 1A
battery charge. In case of power decay, a battery back-up is activated immediately. The output for the recorder is
protected with a 5A polymer fuse. 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.
