E900EL

E series converters are intended to measure and convert electrical parameters in 3-phase 3-wire and 3-phase 4-wire electrical AC mains into the unified output DC signals and sequence of digital signals for transmission through interfaces RS485, Ethernet (protocols Modbus RTU, Modbus TCP, IEC 60870-5-101, IEC 60870-5-104).

E series converters may be used for:

– control of main electrical parameters in 3-phase mains;

– technical metering of electric power.
