SPECIFICATION
SilverStone GEMINI
ST30GF
1U Narrow Redundant Switching Power Supply
With Active PFC
300W+300W
1. General
This is the specification of Model ST30GF; it is intended to describe the functions and
performance of the subject power supply. This 300 watts Redundant Power Supply with
Active PFC (Power Factor Correction) capability, meets EN61000-3-2 and equips Full
Range Input features.
2. AC Input Specifications
2.1 AC Input Voltage, Frequency and Current (Rating: 100V-240Vac, 47-63Hz, 5-2.5A)
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.
Table 1 – AC Input Voltage and Frequency
2.2 AC Inrush Current
The power supply must meets inrush requirements of any rated AC voltage, during turn on
at any phase of 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 rating of its critical components (including input fuse, bulk rectifiers,
and surge limiting device).
2.3 Input Power Factor Correction (Active PFC)
The power factor at full load shall be 0.98 at 115V input voltage.
The power factor at full load shall be 0.90 at 230V input voltage.

2.4 Input Current Harmonics
When the power supply is operated in 90-264Vac of Sec. 2.1, the input harmonic current
drawn on the power line shall not exceed the limits set by EN61000-3-2 class “D” standards.
The power supply shall incorporate universal power input with active power factor
correction.
2.5 AC Line Dropout
An AC line dropout of 17mS or less shall not cause any tripping of control signals or
protection circuits. If the AC dropout lasts longer than 17mS the power supply should
recover and meet all turn on requirements. The power supply shall meet the regulation
requirement over all rated AC voltages, frequencies, and output loading conditions. Any
dropout of the AC line shall not cause damage to the power supply. An AC line dropout is
defined as a drop in AC line to 0VAC at any phase of the AC line for any length of time.
3. DC Output Specification
3.1 Output Current / Loading
The following table defines power and current rating. The power supply shall meet both
static and dynamic voltage regulation requirements for minimum load condition.
Table 2– Output Loads Range 1
Note 1: Maximum continuous total DC output power should not exceed 300W.
3.2 DC Voltage Regulation, Ripple and Noise
The power supply output voltages must stay within the following voltage limits when
operating at steady state and dynamic loading conditions. All outputs are measured with
reference to the return remote sense (Returns) signal. The +5V, +3.3V, +12V, -12V and
+5VSB outputs are measure at the power supply connectors references to Returns. The +5V
and +3.3V is measured at its remote sense signal (+5VS, +3.3VS) located at the signal
connector.
