(Rail Mounted)YFM18S Single-phase Electronic Energy Meters

1. Overview
The DDS-2P and DDS-4P rail mounted single-phase electronic watt-hour meters are single-phase and two-wire watt-hour meters developed by us by applying micro-electronic technologies, dedicated large-scale integrated circuits and digital sampling and processing technique. They are suitable for metering of single-phase AC active energy with a reference voltage of 220V or 230V and a frequency of 50Hz. Technical performance of the meter meets technical requirements of GB/T17215.321 -2008 Static Meters for Active Energy (Classes 1 and 2) and relevant technical requirements of Class 1 single-phase active energy meters In IEC62053-21. The meter measures the active energy consumption with a 6-dlgit pulse register. The product has a wide voltage range, a high reliability, a long life, a high accuracy and a low power consumption and has a function of protection against power theft. The advanced electronic production process Is adopted, strict quality management assurance and rail mounted modular design are applied, the product has a small size, is easy to install and can be widely used for single-phase electric energy metering in urban, rural regions or factories and enterprises and can be installed in a centralized manner.
