DESCRIPTION

The MMW 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 10-40VDC and 18-75VDC. 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 have UL60950-1

approvals and are best suited for data communication equipment, distributed power systems, telecommunications equipment, mixed

analog/digital subsystems, process/machine control equipment, computer peripheral systems, and industrial robot systems.

SPECIFICATIONS: MMW 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.
