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.
