• Industry Standard Pinout
DESCRIPTIONS
The 500WFR series single output power modules are 3.3 to 6
watts high efficiency, low profile dc-dc converters that operate
over a wide input voltage range of 4.5 - 9 VDC, 9 - 18 VDC, 18 - 36
VDC and 36 - 72 VDC and provide precisely regulated output
voltages of 3.3V, 5V, 12V, and 15V.
The -25^oC to +71^oC 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.
