1. the output voltage of the UPS inverter is converted to the required load application voltage, providing the electrical isolation between the load and the UPS. 2. products are usually combined with inductance and transformer and are combined with the capacitor of the output terminal to play the role of the LC filter to make the output voltage reach a sinusoidal waveform. 3. the short circuit impedance voltage of this type of transformer is higher than that of Ucc%.
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.
