Product Description Rectifier/Power Factor Correction (PFC) Circuit In normal operation, the Liebert GXT3’s rectifier/power factor correction (PFC) circuit converts mains power to regulated DC power for use by the inverter while ensuring that the wave shape of the input current used by the UPS is near ideal. Extracting this sine wave input current achieves two objectives: • Efficient power use by the UPS • Reduced reflected harmonics This results in cleaner power being available to other devi
