4. General functions and technical specification
PS-103-20A executed in the metal case with fastening for installation on vertical wall
inside a ship. On a sidewall of the case there is a switch with the indication of an input voltage
(in the manual-on position).
A PS-103-20A supply from an alternating current circuit ~110/220V, 50Hz and
generates direct voltage 24V. Design of the device provides four output terminals for
simultaneous connection of four loadings.
Electric circuit PS-103-20A includes step-down transformer, electronic rectifier, circuit
of switching to emergency supply and alarm signaling.
In case of malfunctions in work of the device in order to provide no failure of the
equipment connected to PS-103-20A, except for the basic power, it is brought emergency supply
from reserve sources (accumulators) on terminal XS9.
