1. Technical description.
1.1 General description.
The stabilized PSU PSDC04122T is intended for supplying CCTV devices requiring stabilised voltage of
12V DC. The output voltage adjustment range is adjusted via a potentiometer within the range of 12,0V÷15,0V DC.
The PSU features 4 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.
