MPU/MDU150 SERIES
®
The innovative MPU150 incorporates Power Factor Correction (PFC)
with a low profile package designed to meet 1U height constraints.
The MPU150-4530 and MPU150-4350 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 MDU150 series provides the same benefits as the MPU150 series,
with nominal 48 volt DC input.
FEATURES
• Power Factor Correction (PFC) Meets EN61000-3-2
