DMED330 - 3PH C/W OR W/O NEUTRAL CT 5A

Why Choose the DMED330?

Lovato DMED330 is a three-phase energy meter for DIN rail panels, engineered for precise monitoring of imported/exported active and reactive energy. Supporting CT /5A or /1A connections and an IEC maximum current of 5 A, the DMED330 achieves Class 0.5s active energy accuracy and Class 2 reactive energy. An integrated RS485 communication port enables straightforward system integration in industrial and commercial switchboards.

Built for reliability, it offers 250 V rated insulation and 6 kV impulse withstand to IEC/EN requirements. Operating from -25 to +55 °C, it suits demanding environments. The device conforms to IEC/EN 61010-1, IEC/EN 61010-2-030 and IEC/EN 50470-1, and weighs 332 g for easy handling during installation. Note: this model is not MID certified or expandable, and does not perform harmonic analysis.
