Isolation transformer high-impedance for UPS,EPS

Isolation transformer high-impedance for UPS,EPS

High-impedance isolation transformer, with structural volume, compact structure,safety and reliability, easy installation and maintenance, compared to separate transformer and choke equipped. The weight ,cost and dissipation of product reduce significantly and electricity efficiency improves because of the decrease in wire consumption. In addition, the inductance value can be made high enough to better meet the requirements of circuital filtering.

This series transformers are widely used for high-power UPS and EPS and accumulator high-frequency charging unit.
