1. Technical description.
1.1. General description.
The
R1624T
power supply unit is designed for uninterrupted power supply of up to 16 HD cameras requiring
stabilized voltage of
24V DC
with the total current efficiency of
8A
.
The output voltage adjustment range is adjusted
via a potentiometer within the range of
2
0V÷26V DC
. The PSU is fitted with 16 outputs protected independently
with melting fuse 0,5A. 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.
