Note 1: Maximum continuous total DC output power should not exceed 400 W.
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.
