2.2

Output Power/Currents

The following table defines power and current ratings for this 200 Watt continuous (300 Watts
peak) power supply. The output power shall not exceed the rated output power. The power
supply must meet both static and dynamic voltage regulation requirements for the minimum
loading conditions. Outputs are not required to be peak loaded simultaneously.
Voltage Rail
NOTE: The total combined power for +3.3V & +5V should not exceed 120W. The total combined power for +12V, -
12V, 5Vsb should not exceed 300W.
2.3

Voltage Regulation

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
COM/GND (black wire)

Protection Circuits

Protection circuits inside the power supply shall cause only the power supply's main outputs to
shutdown. If the power supply latches off due to a protection circuit tripping, an AC cycle OFF
shall be able to reset the power supply.

2.4.1 AC Inrush Current Regulation

The power supply shall have current limit to prevent outputs from exceeding threshold values. If
the current limits are exceeded the power supply shall shutdown. This will be cleared by an AC
power interruption. The power supply shall not be damaged from repeated power cycling in this
condition. The 5Vsb shall be protected under over-current or shorted conditions so that no
damage can occur to the power supply.
