PerFormanCe POWER PFC500
The PFC500 products of the PerFormanCe Power series combine high
performance midrange power with high power density (4.4 watts/in
3
),
active Power Factor Correction (PFC) and high reliability to meet the
requirements of commercial and industrial systems.
Providing tightly regulated DC power, the PFC500 is delivers full
output performance with only 300 Linear Feet per Minute (LFM)
forced air cooling (factory installed fan optional). Other features
include remote sense, power fail, logic level inhibit, DC power good.
Main channel current sharing is provided for redundant applications.
The PFC500 is 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.
FEATURES
• Power Factor Correction (PFC) Meets EN61000-3-2
• Fully Regulated Outputs
• Remote Sense
• Current Share, Power Fail, and Power Good Signals
