Product Description

1 Brief

This series of three-phase multi-function meters integrates high-precision power parameter measurement, digital input, digital output, 4-20 mA analog output, and network communication. It can directly upload data to the local platform through LoRa wireless or Ethernet , RS485 interface. The meter adopts panel embedded installation, with beautiful appearance, reliable operation, and convenient on-site wiring and operation. It can be widely used in substation automation systems, intelligent high and low voltage switchgear panel, low-voltage distribution automation systems, building energy monitoring systems, and other electricity power transmission and distribution site.
