Three-phase DIN-rail energy meter (CT connected)

It can be used for energy monitoring in a wide range of applications, including PV energy management, smart buildings and industrial equipment.

DTSU208

The DTSU208 is a three-phase four-wire electronic DIN-rail energy meter. It is designed to measure electrical parameters including active energy, reactive energy, voltage, current, power, power factor and frequency. Through its RS485 interface, it provides power monitoring data to inverters and other equipment for fast-response control. It supports standard DIN-rail mounting and features a compact size and easy installation.

It is widely used for power data monitoring in distributed PV systems, energy storage systems and other renewable energy applications.
