High-impedance isolation transformer adopts dual-core design, with structural volume, compact structure,safety and reliability, easy installation and maintenance. Compared to separate transformer and choke, the weight ,cost and power loss reduce significantly and electricity efficiency improves . In addition, the inductance value can be high enough to meet the requirements of circuital filtering.

High-impedance isolation transformers are widely used for Energy Storage System, high-power UPS and EPS.
