• Manufacturer Part Number: bbs-2003
• Description: High, Small Bare Bone System
• Manufacturer: BOSER Technology Co., Ltd

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.

4.1.1 Input Specifications
4.1.2 Output Specifications
Output Min. Load Rated Load Peak Load Voltage Accuracy
+12V
-12V
+5V
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:
input or 60A at 230VAC input, cold start, 25°C, with exclusion of EMI
suppression capacitors
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
