DDM100SCR3 Single-phase Three-wire Electronic DIN-rail Active Energy Meter with RS-485 Communication

APPLICATION

DDM100SCR3 single phase three wire DIN-rail active energy meter,with RS485 communication.

The meter is used to measure 50Hz or 60Hz active energy consumption from single phase three wire AC electricity net.

The features of small size and DIN-rail mounting make it suitable for installation in distribution boards and small standard enclosures.

The meter is widely used in the office buildings, shopping malls, residences, airports and metro,etc.

The meter has RS485 communication module, which is convenient to meter-reading.
