1.1 General description.
The PSDCSEP08128 stabilized power supply is designed to supply HD cameras or other devices requiring
stabilized voltage of 12V DC. The power supply has 8 independently adjustable channels with selectable voltages
in the range 12V÷15V DC / 8x1A, thus compensating voltage drops in large CCTV installations. Power supply
outputs are galvanically separated and protected by fuses. A failure (short circuit) in the output circuit will cause the
fuse to blow and disconnect the circuit from DC power (+ U).
