※ –12V,+3.3V, +5V,+12V will have the regulation to ±10% when all load take off.
The +3.3V and +5V total output shall not exceed 90watts. The +3.3V, +5V and +12V total output
shall not exceed 180watts and the total output for this subject power supply is 180 watts. Ripple and
noise measurements shall be made under all specified load conditions through a single pole low
pass filter with 20MHz cutoff frequency. Outputs shall bypassed at the connector with a 0.1uF
ceramic disk capacitor and a 10uF electrolytic capacitor to simulate system loading.
