Shinenergy UPS transformer is well used in power supply area.

UPS is usually equipped with an output transformer, which is used to boost the output of the inverter section. The output transformer UPS has the advantages of high efficiency, small size, high input power factor and wide range of input voltage.

Harmonic currents generated by nonlinear loads can cause problems in the power system. Transformers are particularly vulnerable to overheating and premature failure. To protect against transformer overheating caused by harmonics, designers can specify derated equipment, i.e., oversized transformers that will run at a fracton of their rated capacity, or K-factor transformers specifically designed to accommodate harmonic currents. K-factor transformers are preferred because they have additional thermal capacity of known limits, design features that minimize harmonic current losses, and neutral and terminal connections sized at 200% of normal. K-factor transformers allow operation up to nameplate capacity without derating.
