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
