Electronic power factor correction (PFC)
Rugged industrial quality
Up to 4500W per 19” shelf
Full electronic protection
Fan cooling
Field-proven design
PFC 1K5 module: 5 x 5 x 12.5”
Hot swappable, N+1 redundant
(depth excludes connector)

3U x 19” stainless steel cradle with 3 x PFC 1K5 modules

This modular, industrial quality AC/DC power supply system with power factor corrected input is built with three 1500W, PFC 1K5
power supply modules assembled on a 3U x 19” stainless steel cradle (CR 3U-3). The PFC 1K5 units are equipped with connectors
which allow hot insertion. A built-in redundancy diode in each module allows for parallel connection and N+1 redundant operation.
The system delivers a maximum of 4500W or 3000W with N+1 redundancy. The PFC 1K5 modules are based on field-proven
topology. They have large design headroom and are rated for operation over the specified temperature range without de-rating.
Each module is cooled by a high quality built-in fan. Full electronic protection and the use of components with established reliability
results in a high demonstrated MTBF confirmed by a track record in numerous applications. The system is manufactured at our
plant under strict quality control.
