DESCRIPTION

The MSLUH series power modules are 1W DC/DC converters that are specially designed to provide high levels of isolation (3000VDC) in a

miniature “gull-wing” SMT package. These converters operate over input voltage ranges of 4.5~5.5VDC, 10.8~13.2VDC, and

21.6~26.4VDC. This series also has single and dual output voltages of 3.3, 5, 12, 15, ±5, ±12, and ±15VDC. These converters impressive

efficiencies enable them to deliver their fully rated output power from –25°C to +75°C without a heat sink or forced-air cooling. These

converters are useful for a variety of applications including distributed power systems, data communication equipment, telecommunication

equipment, and industrial robot systems.

SPECIFICATIONS: MSLUH 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.
