PZ series three-phase power meter and energy meter, adopt AC sampling technology, can directly or indirectly measure the three-phase power grid voltage, current, power, energy and other electrical parameters. It can be used for local display, and can be connected with industrial control equipment to form a measurement and control system.
The PZ series three‑phase power and energy meters are designed for AC measurement and can be connected to SCADA or energy‑management systems via an RS‑485 Modbus‑RTU interface. The meters support up to four measurement channels and provide functions such as active/reactive power, power factor, frequency, and voltage/current monitoring.
This manual covers product specifications, mechanical dimensions, wiring diagrams, terminal assignments, and step‑by‑step installation procedures, including mounting, terminal connections, and communication configuration. This manual is written in Chinese.
