Product Overview

Voltage transformers are produced by the company YuanXing Electronics, which is a recognized leader among voltage transformers manufacturers. YuanXing’s mini voltage transformer product line has been specifically designed for use in high-density, electronic environments and is designed as a solution for B2B manufacturers that require high quality and reliable signal transformation (high accuracy) in limited footprint areas (e.g., space-constrained environments), such as smart meters and compact energy monitoring devices.

As high-performance voltage measurement transformers, these units offer best-in-class accuracy in signal transformation using advanced encapsulation technology to achieve a Class of Precision 0.1 or 0.2 (as outlined by IEC 61869-3); thereby providing phase stability and linearity required by professionals who utilize precision instruments. While the mini voltage transformer series is small, it has been designed to offer a robust 2500V isolation voltage for one minute and a dielectric resistance rating of 1000 MΩ @ 500 Vdc. These features provide an extra layer of safety and ensure the integrity of the signal.

This voltage transformer series has been designed for surface mount applications to make it easy for manufacturers to make the proper electrical connections to the device. Additionally, the mounting pattern is non-symmetrical to help prevent incorrect assembly during mass production. In contrast to a typical medium voltage potential transformer, which is designed for power distribution, YuanXing’s space-constrained potential transformers are designed to perform precise secondary sensing as the electrical load varies. The operating frequency range of this component is from 50 Hz to 400 Hz, and the maximum rated load resistance is 100kΩ; therefore, it provides consistent performance under different electrical load conditions
