3.1 Output Current / Loading 
The following tables define two power and current rating. The power supply shall meet both 
static and dynamic voltage regulation requirements for minimum load condition.

Note 1: The +5 & +3.3 Volt total output shall not exceed 170 W. 
Note 2: The +5, +3.3 & +12 Volt total output shall not exceed 280W. 
Note 3: Maximum continuous total DC output power shall not exceed 300W. 
Note 4: Cold-start peak power shall not exceed 450W. 
Note 5: Under normal operating conditions, peak power shall not exceed 360W. 
 
3.2 DC Voltage Regulations, 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, +12V1, +12V2, -5V,-12V 
and +5BSB 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.

Ripple and noise shall be measured using the following methods: 
a) Measurements made differentially to eliminate common-mode noise 
b) Ground lead length of oscilloscope probe shall be 

≤ 0.25 inch. 

c) Measurements made where the cable connectors attach to the load. 
d) Outputs bypassed at the point of measurement with a parallel combination of 10uF 
tantalum capacitor in parallel with 0.1uF ceramic capacitors. 
e) Oscilloscope bandwidth of 0 Hz to 20MHz. 
f) Measurements measured at locations where remote sense wires are connected. 
g) Regulation tolerance shall include temperature change, warm up drift and dynamic load
