The innovative MPU products incorporate Power Factor Correction
(PFC) with a low-profile package designed to meet 1U height
constraints. The MPU150-4530G and MPU150-4350G 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 multiple output 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.
RoHS Compliant
