ESCRIPTIONS
The 500HFR series power modules are high efficiency, low
noise, 5 watt low-profile dc-dc converters. The 5 watt converters
operate over a wide input voltage range of 9 - 36 VDC or 18 - 75
VDC and provide precisely regulated output voltages of 3.3V,
5V, 12V, 15V, ±5V, ±12V and ±15V.
The -25
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.

Capacitor mounted close to the power module helps ensure stability of the unit, it is recommended
to use a good quality low ESR capacitor of 4.7
μF
for the 24V input devices
and a 2.2μF for the
NC = No Connection
48V devices.
