SPECIFICATION
SilverStone ST30NF for Standard
Switching Power Supply
With Active PFC
PS/2 Fanless 300W
1. General
This specification describes the electrical characteristics, functional and physical of a PS/2
Fanless Switching power supply; the maximum output will be 300W when Input Voltage is
from 180V to 240V; the maximum output shall be 250W when Input Voltage is from 100V
to 240V. This power supply is also design with Active PFC (Power Factor Correction)
capabilities.

2. AC Input Characteristics
2.1 AC Input Voltage, Frequency and Current (Rating: 100V-240Vac, 47-63Hz, 6-3A)
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 AC Input Current and Inrush Current
AC input current of the system shall meet the limits shown in Table 1. No damage shall occur
or overstress
or overstress
input fuse shall blow (as a result of inrush). Under conditions; 132/264VAC
full load turn off

C air ambient cold start.
2.3 Input Power Factor Correction (Active PFC)
The power factor at full load shall be ≧
0.96 at nominal 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.
