300-500W EUROCARD (VME) PFC INPUT STAGES
PFC250 & PFC500 SERIES
• Compact size
• Plug-in or stand-alone
• Electronic power factor correction
• Parallel connection for any output power
• N+1 redundancy possible
• Convection cooled
• Full electronic protection
• Telecom quality
• Field-proven design topology
• Eliminates the need to replace entire
power system
The PFC250 & the PFC500 Series of AC/DC converters use an advanced high frequency conversion
technology to generate an output of 360VDC at 300 or 500W. The use of these input stages allows one to
comply with PFC requirements without having to replace the existing system. Since the PFC modules are also
available in plug-in versions, and can be connected in parallel via built-in redundancy diodes, larger PFC
systems can be put together by inserting the required amount of modules into a card shelf. Within the shelf the
PFC modules can be combined with DC/DC converters resulting in complex n+1 redundant power systems.
All PFC modules feature low component count and high efficiency. The use of professional quality
components and rigorous quality control results in an MTBF exceeding 100,000 hours at 45oC.
