DDSU228 Single phase rail type electric energy meter (1P)

Overview

The DDS228 rail type energy meter is a new type of single-phase electronic energy metering product developed by our company. This product complies with the technical requirements for Class 1 and Class 2 static AC active energy meters in GB/T17215.321-2008 and IEC62053-21 international standards, and is suitable for measuring single-phase AC active energy with a reference voltage of 220V or 230V and a frequency of 50Hz or 60Hz. This product is suitable for a wide voltage range, high reliability, long lifespan, high accuracy, low power consumption, and has functions such as anti-theft. It adopts a guide rail structure design, with a small volume and easy installation. It uses a standard 35mm guide rail installation interface that is internationally recognized! It can be widely used for single-phase energy metering and centralized installation in urban, rural, or factory enterprises.
