1. Technical description.
1.1. General description.
The RUPS812T buffer power supply unit is designed for uninterrupted power supply of up to 8 analog
cameras requiring stabilized voltage of 12V DC (+/- 15%). The PSU provides voltage of U=13,8V DC. Current
efficiency:
Output current 8A + 1A battery charge.
Total device c battery: 9A max.
In case of power decay, a battery back-up is activated immediately. The PSU is fitted with 8 outputs
protected independently with melting fuse 1A. 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.
