Pioneer’s Modular PFC Product Series can also be used in applications where 400VDC non-isolated single output bulk power converter is required. With PFC, output power can be maintained with a 30% reduction in RMS line current. Other advantages include improved hold-up performance, reduced line harmonics (for 1φ input only), and insensitivity to voltage and frequency variations. Because they effectively eliminate harmonic currents, the converters are ideal for applications where neutral wire current exceeds recommended ratings due to waveform distortion caused by the typical off-line units.

Additional benefit of the bulk power converter is that it eliminates the need for switches and jumpers to adapt the supply for 110VAC or 220VAC operation, creating a “Universal Input” power unit. The input voltage on the bulk PFC converter is boosted to provide a nominal 400VDC output for conventional pulse width modulated (PWM) power supplies or distributed DC bus network. It meets the most stringent international safety and EMI standards, including the IEC555-2 which limits line current harmonic content to less than 5% (for 1φ input only).

With wide input range, the bulk power series can deliver up to 10,000 watts. Operating temperature ranges from 0°C to +50°C at full load. Improvements in electrical and heat transfer technology allow component stresses to be kept well within manufacturers’ rating, insuring high reliability.
