PerFormanCe POWER PFC375
The PFC375 products of the PerFormanCe Power series
incorporate high performance midrange power, active Power
Factor Correction (PFC), and high reliability to meet varied
commercial and industrial requirements.
Providing tightly regulated DC power in a wide variety of single
and multiple output configurations, the PFC375 is designed to
provide full output power 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, and
DC power good. Main channel current sharing is provided for
redundant applications. The PFC375 is available with SAE
mountings or optional metric mountings.
The PFC375 product line is approved to the latest international
regulatory standards, and displays the CE Mark.
