SPECIFICATION
SilverStone Gemini ST55GF
Mini Redundant Power Supply
With Active PFC
550W + 550W
1. General
This specification describes the electrical characteristics, functional and physical of a
550W+550W=550 watts redundant power supply with Active PFC (Power Factor
Correction) and hot-swappable capabilities.
2. AC Input Characteristics
2.1 AC Input Voltage and Frequency (Rating: 100V-240Vac, 47-63Hz, 10-5A)
The power supply must operate within all specified limits over the input voltage range in
Table 1.
Harmonics distortion of up to 10% THD must not cause the power supply to go out of
specified limits.
2.2 AC Inrush Current
AC line inrush current shall not damage any component nor cause the AC line fuse to blow
under any DC conditions and with any specified AC line input voltage and frequency.
Repetitive On/Off cycling of the AC input voltage shall not damage the power supply.
