ESCRIPTIONS
The 1000XFR series are low-profile dc-dc converters that
operate over input voltage ranges of 18 - 36 VDC and 36 - 75
VDC and provide precisely regulated output voltages of 2.5V,
3.3V, 5V and 12V.
The -40
o
C to +60
o
C operating temperature range makes it
ideal for data communication equipments, mobile battery
driven equipment, distributed power systems, telecommunication
equipment, mixed analog/digital subsystems, process/
machine control equipment, computer peripheral systems
and industrial robot systems.
