DESCRIPTION
The MVAC250 series switching power supplies
utilize advanced component and circuit
technologies to deliver high efficiency. 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.
