1.1 General description.
The
PSCU04344SEP
power supply unit is designed for supply of CCTV devices. The PSU supplies
constant voltage in the range
30÷35V DC
and current efficiency of
I=4x1A
, by a supply line to the
DCDC10H
or
DCDC15H
converters. The choice of the converter is determined by the maximum current consumption of the
camera. The
DCDC10H
converter is designed to supply cameras with current consumption of
0,8A/12V DC max
.
For cameras with max current consumption of
1,2A/12V DC
,
DCDC15H
converter is recommended. The
converters’ voltage is regulated to
12VDC,
enabling power supply of the cameras. The PSU is fitted with 4
independent, galvanically isolated outputs protected by melting fuses.
