EP 4500 Rack UPS make use of the unique double conversion circuitry to detect the electricity current andvoltage output power supply. The current is input via the high frequency PWM to maintain uniform wave from and phase in line with voltage, so as to attain high input power factor over 95% and avoid genrating comparatively significant harmonic interference on the power network. With the use of the outstanding IGBT as the power conversation component, the operating frequency of the Inverter of UPS is capatible of reaching tens og KHz, due to high frequency op Terating characteristics of IGBT. Higher working efficiency of the inverter also improves the overall efficiency of UPS and higher inversion frequency reduces the noise of the inverter as well.
