1. General
1.1 Scope
This specification defines the performance characteristics of a single phase 750 watts, 6
output power supply. This specification also defines worldwide safety and electromagnetic
compatibility requirements for the power supply which is intended for use in computer
products.

2.4 Inrush
Current
The power supply must meet inrush requirements for any rated AC voltage, during turn on
at any phase of AC voltage, during a single cycle AC dropout condition, during repetitive
ON/OFF cycling of AC, and over the specified temperature range. The peak inrush current
shall be less than the ratings of its critical components (including input fuse, bulk rectifiers,
and surge limiting device).
2.5 Efficiency
HPC-750-B14S provides an efficiency of 82% minimum when measured at full load under
115V/60Hz and 230V/50Hz condition.
