Power Supply
The power supply used in the BBS-2003 is a 70W AT power supply.
The specifications and features of this special power supply are listed
in the following sections.
4.1 Specifications
4.1.1 Input Specifications
Input Voltage: The range of input voltage is from 85VAC to 270VAC
Input Frequency: The range of input frequency is from 47HZ to 63HZ
Input Current: The maximum input current is 2A at 115VAC or 1A at
230VAC
Inrush Current:
The inrush current will not exceed 30A at 115VAC
input or 60A at 230VAC input, cold start, 25°C, with exclusion of EMI
suppression capacitors
4.1.2 Output Specifications
Load Range: At factory, the all outputs at min. load conditions, the +5V
output is set to between 5~5.1V, and the other outputs are checked to be
within the specified voltage accuracy range

Ripple and Noise: The peak to peak ripple and noise for output is less than
1% of output voltage at rated load. Measuring is done by 15MHz band-width
limited oscilloscope and terminate each with a 0.47uF capacitor
Line Regulation: The line regulation for each output is less than +/-2%
while measuring at rated load and +/-10% of input voltage changing
Load regulation: The load regulation for +5V is less than +/-3%, for +12V
is less than +/-4%, for -12V is less than +/-5%, measuring is done by
changing the measured output load +/-40% from +/-60% rated load, and
keep other outputs at 60% rated load
