Series HSF
Mission Critical, Fault tolerant Power Supplies

• Hot-swappable plug-in power supplies.
• Designed to be combined in an N+1 fault-tolerant power system.
• Front panel voltage adjustment trimmer for adjustment of output voltage.
• Built-in forced current sharing and or-ing diodes.
• May also be used independently as a multi-output power supply.
• Designed to be sustainable - new models are backward compatible with existing racks.
• Available in 1U and 3U sizes. Mounts in 19-, 23-, and 24-inch equipment racks.
• All models include power factor correction (PFC).
• Full service customized DC power distribution systems can match power supply output(s) with your load(s).
• I/O connections via 24 pin connector that plugs into rack adapter. External connections are made via rack adapter.
• Surface mount technology permits minimum mounting space.
• Entire RA 19 racks populated with HSF power supplies can be connected in parallel, parallel-redundant or series.
• HSF are CE Marked per per the LVD, EMC and RoHS 2 Directives. See applicable Declaration of Conformity.
• Compliant with UL 8750, Standard for LED Equipment,
• Watch video of NEBS GR-63-CORE earthquake and office vibration testing.
  
• HSF can be custom configured for special applications, such as:
  • Space rocket launcher DC UPS (3U HSF modules with custom 3U distribution panel)
  • Air Traffic Control (1U HSF modules with custom prewired 1U power distribution panels)
  • MIL-STD-461 compliance
  • Power Over Ethernet (POE)
• When HSF modules are paralleled, the module with the highest voltage setting automatically becomes the "master." As long as they are in the same voltage range, the other units are slaves, tracking the master voltage setting and equally sharing load current.
• Additional Fault Tolerant Solutions with Kepco's Series HSP (hot swap) and HSM (hard wired).
