The PFC 4K5-3U19 series modular, rack-mount ac/dc power supply system with PFC input delivers 4.5 kW or 3 kW with n+1 redundancy. The series targets critical applications in telecommunications, power utilities and industrial control.
The rack-mount power supply system is made with three 1.5–W (PFC 1K5) power supply modules assembled on a 3U x 19–in. rack-mount cradle. The modules are hot-pluggable and accept 95 to 264–Vac input offer several different output configurations including 24 Vdc/60 A, 48 Vdc/30 A, 54 Vdc/27 A, 110 Vdc/13 A or 125 Vdc/12 A. Efficiency at full load is typically 80%. Protection features include 4,300 Vdc input to output isolation, output current limiting with non-hiccup type short-circuit protection and thermal shutdown with self-resetting.
