Protection features

1 . 1 . 1 . 1 . 1 . Over-power protection

Over-power protection

The power supply shuts down and latches off when output power is within

120 ~ 150 percent of rated DC output.

2 . 2 . 2 . 2 . 2 . Over-voltage protection

Over-voltage protection

No single point fault causes a sustained over-voltage condition on any or all

outputs. The power supply provides latch-mode over-voltage protection as

defined in the following table.

O u t p u t

+12V1DC

+12V2DC

+5VDC

+3.3VDC

3. Short-circuit protection

The power supply can withstand a continuous short-circuit to the output without

damaging or overstressing the unit. The power supply shuts down and latches

off for shorting the +3.3V, +5V, +12V1, +12V2, or -12V rails to return. Shorts

between main output rails and +5VSB do not cause any damage to the power

supply.

4. Over-current protection

Overload currents applied to each tested output rail will cause the output to trip

before reaching or exceeding 240 VA. For testing purposes, the overload

currents should be ramped at a minimum rate of 10 A/s starting from full load.

Warning!

To reduce the risk of fire, electric shock, body injury, or damage to the power supply

and/or your computer system, take the following safety precautions:

• Never open or dismantle the power supply!

• Do not remove the power supply while the system is on.

• Do not unplug the AC power cord while the system is on.

• Do not put the power supply where it can get wet.

Troubleshooting

If the power supply fails to function properly, do the following:

• Check if the AC power cord is plugged firmly.

• Check if the extension power cord is switched on.

• Check if the voltage switch is set to the appropriate position (115V or 230V).

• Check if the main power connector is firmly plugged into the socket.

• Disconnect the power cord to reset the power supply. Reconnect after 30

seconds or so.
