DESCRIPTION
The MVAB120 series switching power supplies
utilize advanced component and circuit
technologies to deliver high efï¬ciency. Designed
for Medical, Telecom, and Industrial applications
to satisfy 1U height design considerations, the
MVAB120 Series measures only 2.0" x 4.0"
x 1.35". All models offer universal AC input
with active power factor correction (PFC) and
compliance to worldwide safety and EMC
standards.

2 Ripple and noise are measured with 0.1 μF of ceramic capacitance and 47 μF of electrolytic capacitance on each
of the power supply outputs. The output noise requirements apply over a 0 Hz to 20 MHz bandwidth. A short
coaxial cable with 50Ω scope termination is used.
3 Unless otherwise speciï¬ed, all readings are taken at 120Vac input and 25°C ambient temperature.
