UPS (EPS)

Product description:
1.The product converts the UPS inverter output voltage into the required load application voltage, thus providing the electric isolation between load and UPS.
2.The product is usually of the combination form of inductance and transformer and combines with the capacitance of output end, which acts as LC filter, making the output voltage reach sinusoidal waveform.
3.The short-circuit impedance voltage Ucc% of this kind of transformer is relatively high.
