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.
