ESCRIPTIONS
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.
The -40
o
C to +71
o
C operating temperature range makes it ideal
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.
