▶ Overview
The PC321 ZigBee 3-Phase Clamp Energy Meter is a professional, non-intrusive power monitoring solution designed for residential, commercial, and light-industrial energy management projects. Using split-core current transformer (CT) clamps, it delivers accurate real-time energy measurement without cutting cables or interrupting power, making it ideal for both new installations and retrofit projects.
Available in both Tuya and MQTT versions, the PC321 supports flexible integration with smart energy management platforms, including Home Assistant. It is well suited for sub-metering, solar energy monitoring, EV charging, HVAC systems, and building energy management applications where reliable wireless communication and scalable deployment are essential.
As part of OWON's smart energy portfolio, the PC321 can work alongside ZigBee gateways, smart relays, and other energy management devices, enabling integrated monitoring and automation for residential, commercial, and industrial energy projects.
