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.
RoHS Compliant
Greater than 1 million hours demonstrated MTBF
Power Factor Correction (PFC) meets EN61000-3-2
Fully-regulated outputs
Main output remote sense
Current Share, Power Fail, and Power Good signals
Overtemperature, overvoltage, and overcurrent protected
Available with metric and SAE mountings
