NOTES:
1) For AC input, use PFC500 prefix; use PDC500 prefix for DC input versions.
2) Consult factory for availability of 28V and 48V units with DC input.
3) Output currents ratings are expressed with 300 LFM forced air.
4) Remote sense connected. See Application Note #P1 for load regulation when using the D option for 24V units.
5) Maximum peak to peak noise expressed as a percentage of output voltage, 20 MHz bandwidth.
For ripple/noise on “D” option models, see options data on page 3.

www.power-one.com
The PFC500/PDC500 products of the PerFormanCe Power Series combine high performance midrange power with
high power density (4.4 watts/in3) and high reliability to meet the requirements of communications, commercial, and
industrial systems.
Providing tightly regulated DC power, the PFC500/PDC500 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, and AC input units can be paralleled with DC input versions. Units are available with SAE
mountings or optional metric mountings.
The PFC500/PDC500 product line is approved to the latest international regulatory standards, and displays the CE
Mark.
