PerFormanCe POWER PFC250
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 PFC250-4530
and PFC250-4350 provide high current +3.3V and +5V on a single
platform to support mixed mode, high-speed digital circuitry.
Power-One's 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 PerFormanCe Power PFC250 meets international safety
requirements and is CE Marked to the Low Voltage Directive.
FEATURES
Active Power Factor Correction (PFC) Meets EN61000-3-2
