Insulation Monitoring Relay (RKI) with DC Meter Function

51 000 ₽

A unique product with the ability to monitor electricity in consumption mode, including as part of DC charging stations.

The RKI is intended for:

monitoring the quality of insulation coating in electric vehicle charging cables using GB/T, CHADEMO and CCS technologies in «Mode 4» in accordance with GOST R IEC 61851 and managing electrical subsystems of the charging station;
measuring insulation resistance (leakage currents) in DC circuits with insulated busbars up to 1000 V and switching electrical circuits in protection and automation devices when insulation resistance falls below a certain, preset value;
managing the station’s electricity meter, measuring consumption.
