▶ 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. By using current transformer (CT) clamps, the PC321 enables accurate real-time measurement of electricity consumption without cutting cables or interrupting power.
Built on ZigBee 3.0, the PC321 is ideal for smart buildings, BMS integration, sub-metering projects, and OEM energy platforms, where stable wireless communication, scalable deployment, and long-term reliability are essential.
As a manufacturer, OWON delivers this product as part of a complete smart energy ecosystem, supporting gateways, sensors, relays, and open APIs for system-level integration.
