Product details
■ Product Overview
The DDZ2027 single-phase energy meter adopts an advanced microcontroller processing system for data acquisition, processing, and storage. It has the characteristics of good resistance to electromagnetic interference, low power consumption, anti-theft, and long service life. The function of this energy meter is to measure single-phase active energy with a rated voltage of 220V and a rated frequency of 50Hz, and can be optionally equipped with time-sharing billing, prepaid electricity, valve control, dual protocol and other functions according to customer needs. All technical indicators comply with the design standards of GB/T 17215.321-2008 and DL/T 645-2007.
