Charge-rectifier devices of modular type of series "NRTM" are used at various power facilities and industrial enterprises for:
- charging of lead-acid batteries (maintained / low-maintenance / sealed with gas recombination);
- maintenance of ABs in the mode of constant recharging;
- parallel operation with AB on load;
- supply of DC consumers when the AB is switched off;
- provision of galvanic isolation between AC and DC circuits;
- protection of AB and signalling of various types of alarms.
Designation - NRTM (2x) K.N + X.Y, where K / X - rated output current of the main / additional channel (10 - 200 A / 10 - 640 A) / (10 - 60 A), N / Y - rated output voltage of the main / additional channel (24, 48, 110, 220 V) / (24, 48 V).
Structural design - a set of rectifier modules placed in a single cabinet construction. Control and parameter monitoring is performed by the control module.
