1.1. General description.
The R1612T power supply unit is designed for uninterrupted power supply of up to 16 HD cameras requiring
stabilized voltage of 12V DC with the total current efficiency of 14A. The output voltage adjustment range is
adjusted via a potentiometer within the range of 12V÷15V DC. The PSU is fitted with 16 outputs protected
independently with melting fuse 1,5A. 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.
