DESCRIPTION
The MVAB120 series switching power supplies
utilize advanced component and circuit
technologies to deliver high efficiency. 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.

1 Medical versions not designed for DC input voltage.
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 specified, all readings are taken at 120Vac input and 25°C ambient temperature.
