The PerFormanCe Power PFC250 Series combines Power Factor Correction (PFC) with wide-range outputs to meet the requirements of data communications and industrial controls. The PFC250-4530G and PFC250-4350G provide high current +3.3 V and +5 V on a single platform to support mixed-mode, high-speed digital circuitry. Bel Power Solutions unique dual-converter architecture combines high reliability with exceptional regulation. All models feature remote sense on outputs V1 and V2 to provide independent compensation of output cable losses. Other standard features include independent current sharing on V1 and V2, thermal shutdown, and remote inhibit. Airflow of 300 linear feet per minute (LFM) is required to deliver the full power density of 3.0 watts per cubic inch. The PerF ormanCe Power PFC250 meets international safety requirements and is CE Marked to the Low Voltage Directive.
