2.9 Electrical Discharge, IEC61000-4-2
In addition to IEC61000-4-2, the following ESD tests should be conducted. Each surface 
area of the unit under test should be subjected to twenty (20) successive static discharges, at 
each of the follow voltages: 2KV, 3KV, 4KV, 5KV, 6KV and 8KV. 
All power supply outputs shall continue to operate within the parameters of this 
specification, without glitches or interruption, while the power is operating as defined and 
subjected to 2kV through 10kV ESD pulses. The direct ESD event shall not cause any out of 
regulation conditions such as overshoot or undershoot. The power supply shall withstand 
these shocks without nuisance trips of the Over-Voltage Protection, Over-Current Protection, 
or the remote +5VDC, +12VDC shutdown circuitry.

3. DC Output Specification
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. 
Table 5 - Load Range 1
Note 1: The +5 & +3.3 Volt total output shall not exceed 180 W. 
Note 2: The +5, +3.3 & +12Volt total output shall not exceed 526W.
Note 3: Maximum continues total DC output power shout not exceed 550W.
