Product Overview

YuanXing Electronics has developed a range of specially designed dc immune current transform, which are used by B2B manufacturers of Electronic Watt Hour Meters. The design of these products is in accordance with the IEC 62053-21 and IEC 62053-23 Industry Standards to ensure that they have a high level of accuracy (class 0.1 and class 0.2) when subjected to DC Current Components, thereby preventing core saturation.

The dc immune current transformer is constructed with a high strength epoxy encapsulation and possess an isolation resistance of 1000 MΩ when tested at 500 Volts DC. They can be operated at frequencies in the range of 50/60 Hz and have a temperature operating range from -40°C to +70°CDe­grees Celsius. Therefore, they provide optimal reliability of operation under a variety of grid conditions. The “DC Immune Current Transformer” series can be supplied in more than ten different sizes for mounting on printed circuit boards (PCBs) or via wire leads. The DC immune current transformer series provides the stability necessary to operate effectively in today’s energy metering environments.
