High-impedance isolation transformer/EPS/UPS
This series transformers are widely used for high-power UPS and EPS and accumulator high-frequency charging unit.
Advantages:
1.High-impedance isolation transformer with structural volume and compact structure,
2.safety and reliability,
3.easy installation and maintenance, compared to separate transformer and choke equipped.
4.The weight ,cost and dissipation of product reduce significantly and electricity efficiency improves because of the decrease in wire consumption.
5. Inductance value can be made high enough to better meet the requirements of circuital filtering.
