This series of single-phase power meter integrates high-precision power parameter measurement, switch input, relay output, 4-20mA analog output, and network communication with digital technology. It can share data with the local platform through LoRa wireless network, or RS485 connection. The meter adopts embedded installation, with a beautiful appearance, reliable operation, and convenient on-site wiring and operation. It can be widely used in important substation automation systems, intelligent high and low voltage switchgear, low-voltage distribution automation systems, building energy monitoring systems, and other important power transformation and distribution situations.
