1.1 DESCRIPTION
The Product is designed to operate with single-phase mains 50 (60) Hz
110; 220 V AC and provide regulated voltage of 24 V DC to different shipborne and in-
dustrial equipment. The PCH ensures charge of connected storage batteries in automatic
mode.
1.2 MAIN TECHNICAL SPECIFICATIONS
1.2.1 The Product ensures:
a. charge of connected storage batteries; load power supply with regulated voltage
of 24 V DC;
b. in case of a main power failure the Product automatically switches over the
load to the storage battery and vice versa;
c. charge current and voltage of SB can be set up using a keyboard located on the
Product’s casing, see Figure 1;
d. the following additional units can be connected:
‒BPC-136 to provide remote settings and control of the PCH, and to repeat the
alarm signaling;
‒AU-106 (AU-206) to repeat the alarm signaling of PCH;
‒DTS-135 to control SB temperature.
Note –General technical specifications of these units are represented in
Annex B;
e. short circuit protection of the output contacts;
f. light and visual alarm in case of:
‒power mains failure;
‒SB reverse polarity connection;
‒PCH switching on when SB is disconnected or SC circuit rupture;
‒excessive voltage in power circuit;
‒overload or SC in SB circuit;
‒exceeding the limits of charge current or voltage;

1.3 OPERATION AND STRUCTURE OF THE PRODUCT
1.3.1 General information
The Product consists of two modules: a power supply unit and battery charger.
The modules are self-contained; they are connected by switching unit.
When power supply is available, the switching unit connects load to power sup-
ply unit; in case of power supply loss it automatically switches the load to SB power
supply. Once the power supply is restored, the switching unit automatically switches the
load to the power supply unit; the storage battery charge continues in automatic mode.
The Product allows for automatic charging of connected SBs and, at the same
time, ensures output voltage of 24 V DC to power the load.

SB is charged according to the combined method: operation is carried out in the
mode of current stabilization in the phase of main charge, with switching over to volt-
age stabilization mode in the final phase.
