The 300XFR series power modules are high efficiency, low-

profile, 3 watt dc-dc converters that operate over input voltage

ranges of 4.5 - 9 VDC, 9 - 18 VDC, 18 - 36 VDC and 36 - 75 VDC

and provide precisely regulated output voltages of 5V, 12V, 15V,

±12V and ±15V.

for data communication equipment, mobile battery driven

equipment, distributed power systems, telecommunication

equipment, mixed analog/digital subsystems, process/

machine control equipment, computer peripheral systems and

industrial robot systems.
