Converters are designed for uninterrupted DC power supply of control circuits, protection, automation, signalling, telemechanics, switching devices, high-voltage switches, emergency lighting and other consumers, when the main supply network is switched off, continuous charging and monitoring of the state of accumulator batteries.
The products are used as sources of operational direct current together with the accumulator battery (AB).
The products provide:
a) maintaining charge of the AB with stabilised voltage;
b) charging of discharged AB in automatic three-stage mode (initial charge current limitation stage, voltage limitation stage, thermocompensated voltage stabilisation stage);
c) equalising (equalising) charge of the AB;
d) thermocompensation of AB recharge voltage;
e) automatic control of AB circuit integrity;
f) power supply of power consumers of the DC system in the buffer mode with ABs.
