DESCRIPTION
The MVAC250 series switching power supplies
utilize advanced component and circuit
technologies to deliver high efï¬ciency. Designed
for medical, computing, communications, telecom
and other OEM applications to satisfy 1U height
design considerations, the MVAC250 Series
measures only 3.0" x 5.0" x 1.40". All models
offer universal AC input with active power factor
correction (PFC) and compliance to worldwide
safety and EMC standards.
