Kepco HSF series modular DC Power Supplies

The Kepco HSF series of hot-swappable plugin power supplies are designed to be combined in an N+1 fault-tolerant power system. Built-in forced current sharing and or-ing diodes are provided for this purpose. HSF may also be used independently as a multi-output power supply. The HSF series consists of 50, 100 150, 350, 600, 1200 and 1500 Watt modules than can mixed and matched in one the of the available 19 Inch Rack Adapters to form a DC Power system.

The HSF series are available in 3U and 1U High 19Inch variants, with accompanying rack adapters:

The 3U sizes are comprised of seven power groupings: 50W, 100W, 150W, 300W, 350W, 600W and 1200W/1500W, all of which include power factor correction (PFC).  For the 3U modes several rack adapters are available.

1 HE models

The new low profile HSF-1UR models incorporate power factor correction (PFC) and are rated at 50W, 100W and 150W.  All 1U models are mounted sideways so that up to 4 units may be mounted in the RA 19-1U housing.
