1.  General 
1.1  Scope 
This specification defines the performance characteristics of a single phase 500 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.  Input Characteristics 
2.1  Input Voltage 
Nominal Voltage 
 
 
     Voltage Variation Range 
--------------------- 
 
   
     ---------------------------- 
230 Vrms 
            
         207 - 253 Vrms 
2.2  Input Frequency 
Nominal Frequency   
 
Frequency Variation Range 
------------------------ 
  -------------------------------- 
50 Hz 
 
 
 
 
  47 Hz to 63 Hz 
* The power supply must operate at above frequency with 207 - 253VACrms input voltage range. 
2.3  Max. Input AC Current 
Max. Input Current   
 
Measuring Range 
------------------------ 
  ----------------------- 
4.0A  
                            207 - 253 Vrms 
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-500-H12S provides an efficiency of 75% when measured at full load under 
230V/50Hz  condition.
