1. Technical description.
1.1. General description.
The
PSDCR161214
stabilized power supply is designed to supply HD cameras or other devices requiring
stabilized voltage of
12V DC
. The output voltage adjustment is adjusted via a potentiometer within the range of
12V÷15V
DC
. The PSU features 16 outputs protected independently by either glass fuses.
A failure (a short circuit) in the output
circuit makes a fuse blow and disconnection of the circuit from the DC power supply (+U). The power supply unit is
placed in a metal enclosure (color RAL 9003) with space a recorder.
The enclosure construction is compliant with the
requirements of the General Data Protection Regulation GDPR (the possibility of installing two locks with
different codes).
A micro switch indicates door opening (front cover).
