1.1 General description.
The PSDCSEP04124 stabilized power supply is designed to supply cameras or other devices requiring
stabilized voltage of 12V DC. The power supply has four independently adjustable channels with selectable
voltages in the range 12V ÷ 15V DC / 4x1A, 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).
