The QPDF-480 Series is a 480W single-output enclosed frame power supply with active PFC, designed for universal AC input and full-range operation. It features a 1U low-profile enclosure measuring 218×116.5×41mm with forced air cooling via a built-in DC fan. The unit supports output voltages of 12V, 24V, 27V, 36V, or 48V, with corresponding rated currents of 34A, 22A, 18A, 14A, or 11A, and maintains voltage accuracy within ±2.0%. Efficiency ranges from 88% to 90% depending on the model. It includes over-load, over-voltage, over-temperature, and short-circuit protections with auto-recovery. Input accepts 90-264VAC or 127-370VDC at 47-63Hz with a power factor greater than 0.96. Compliance includes IEC 60950-1, UL60950-1, EN60950-1, EN55022 Class B, EN61000-3-2 Class D, and EN61000-4-2,3,4,5,6,
