1. Technical description.
1.1. General description.
The RUPS1612RP buffer power supply unit is designed for uninterrupted power supply of up to 16 HD
cameras requiring stabilized voltage of 12V DC (+/- 15%). The PSU has two circuits: 1x4A / 12V DC for supplying
the recorder and 16x0,75A / 13,8V DC for both cameras. Current efficiency of the PSU amounts to:
Output current 16x0,75A + 4A recorder + 2A battery charge
Total device current + battery: 18A max.
In case of power decay, a battery back-up is activated immediately.
The approximate backup time is given assuming that all output ports are used (using typical devices and 65Ah
batteria). The electricity consumption for own needs and the energy efficiency of the power intake track were taken into
account. The exact description of how to perform the calculations can be found at: "Approximate backup time -
assumptions for calculations".
The PSU is fitted with 16 outputs protected independently with polymer fuse PTC 1A and the output for the
recorder is protected with the 4A 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.
