The PFC500 products of the PerFormanCe Power Series combine high
performance midrange power with high power density (4.4 watts/in
3
)
and high reliability to meet the requirements of communications,
commercial, and industrial systems.
Providing tightly regulated DC power, the PFC500 delivers full output
performance with only 300 Linear Feet per Minute (LFM) forced-air
cooling (factory-installed fan optional). Main channel current sharing
is provided for redundant applications.
Units are available with SAE mountings or optional metric mountings.
The PFC500 product line is approved to the latest international
regulatory standards, and displays the CE Mark.

CONDITIONS / DESCRIPTION
Add “D” as a suffix to the model number to order factory installed
isolation diodes for parallel or redundant operation. For 24V models
with the “D” option, external caps are required to meet the 1%
noise/ripple spec. Power Good has a pull-up resistor of 475 on the
24V models. See Application Note #P1 for details.
Add “F” as a suffix to the model number to order integral fan.
Fan provides the required 300 LFM of forced air cooling, or
otherwise provided by the end user.
Add “M” as a suffix to the model number to order chassis with M4 x
0.7 mounting inserts.
