Smart Meter For Single Phase Solutions

New Energy Meter Single Phase Two-wire(1P2W)

LHE12D

LHE12D is a single-phase multi-function direct-connect rail-mounted meter.
LHE12D is intended to measure grid parameters, e.g., active energy, reactive energy, voltage, current, power, power factor and frequency. The RS485 interface provides power monitoring data for inverters and other devices to realize fast response control. Standard DIN rail installation, with a small size, easy to install.
Widely used in distributed photovoltaic, energy storage power stations and other new energy fields for powering data monitoring.
