Power good signal shall go to a down level 1ms before +5V output
voltage falls below the regulation limits during PS-ON signal pull high.
2-13. Power Fail Signal (T6)
When the DC outputs (+5V, +12V, +3.3V) have over voltage condition,
the power supply shall provide latch mode over voltage protection.
3-1. Over Voltage Protection
A short circuit placed to ground shall cause no damage or power supply shall be shutdown.
(The contact resistance is 0.05 ohm when the outputs short circuit.)
3-2. Short Circuit Protection
When the power supply latches into shutdown condition due to a fault on an+5V,+3.3V,+12V,
output (OVP, UVP,OCP)and OTP, the protection shall reset after the fault has been removed,
use remote on/off control or recycle the AC power again for a typical of 5 seconds.
3-3. Protection Reset
Any output overshoot at turn on shall be less than 15% of the nominal output value
(with resistive load) as described in sec. 2.1.

2-12. Hold Up Time (T5)
The test environment is 25 C & full
load condition @ nominal input.

At 115/230Vac input the power supply will shut down all DC output within max. 150% of full load.
3-5. Over Power Protection
Max.160% for +5V,+12V,+3.3V dc output rail.
3-6. Over Current Protection
When power supply temperature over 90 C (typ.)The power supply will be shutdown.
FIGURE 3. Operation/Storage Temperature Range
Caution: Fanless power supply recommends the systems require
additional external forced circulation cooling fan to extend product life.
3-7. Over Temperature Protection( Optional )
Operation: 20% to 90% RH(nominal input)
Storage: 5% to 95% RH
4-2. Humidity (none condensing)
Operation:
115V: 0 C to 35 C (Need to increase external forced air cooling) -P1(Note.)
230V: 0 C to 45 C (Need to increase external forced air cooling) -P2(Note.)
