Three-Phase DIN-Rail
A DIN-rail energy meter featuring compact size and easy installation.
Product Description
The three-phase DIN-rail energy meter is primarily designed for real-time measurement of electrical parameters in electrical circuits, including three-phase voltage, three-phase current, active power, reactive power, frequency, and power factor. Via its RS485 interface, it provides critical power monitoring data to devices such as inverters and EV charging stations, enabling fast-response control. Featuring a standard DIN 35mm rail mounting design, it offers significant advantages such as a compact footprint and easy installation.
