DESCRIPTION
The MM series power modules are low-profile dc/dc converters that offer up to 30 watts of output power in a 2 x 1.6 x 0.37 inch package.
These converters operate over input voltage ranges of 9-18VDC, 18-36VDC, and 36-75VDC. This series also provides regulated single
and dual output voltages of 3.3, 5, 12, 15, ±12 and ±15VDC. Other features include remote on/off control, output trim function, six-sided
shielding, and efficiencies up to 89%. All models are over voltage, over temperature and short circuit protected. The EN55022 Class A
conducted noise compliance minimizes design time, cost, and eliminates the need for external filter components. These converters are
best suited for data communication equipment, mobile battery driven equipment, distributed power systems, telecommunications
equipment, mixed analog/digital subsystems, process/machine control equipment, computer peripheral systems, and industrial robot
systems.
SPECIFICATIONS: MM Series
All specifications are based on 25°C, Nominal Input Voltage, and Maximum Output Current unless otherwise noted.
We reserve the right to change specifications based on technological advances.
