1. Technical description.
1.1 General description.
The
PSDC09125T
stabilized power supply is designed to supply analog cameras or other devices requiring
stabilized voltage of
12V DC
. The output voltage adjustment range is adjusted via a potentiometer within the range of
12V ÷ 15V DC.
The PSU features 9 outputs protected independently by glass fuses. A failure (a short circuit) in the
output circuit makes a fuse blow or an activation of the fuse and disconnection of the circuit from the DC power supply
(+U). The PSU is housed in a metallic enclosure with an indication panel.
