3-2. Short Circuit 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.)
3-3. Protection Reset
When the power supply latches into shutdown condition due to a fault on an +5V,+3.3V,+12V,
output (OVP, UVP,OCP), 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.
3-4. Over Shoot
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.
3-5. Over Power Protection
At 115/230Vac input the power supply will shut down all DC output within max 150% of full
load.
3-6. Over Current Protection
Max.160% for +5V,+12V,+3.3V dc output rail.

7. Dielectric Voltage Withstand (HI-POT)
The power supply shall withstand for 3 seconds without breakdown the application of an
1800Vac-supply voltage applied between both input line and chassis (10mA AC Cutoff
current). Isolating transformers shall similarly withstand 4242Vdc applied between both
primary and secondary windings for a minimum of one minute.
8. PFC
Active Power Factor Correction, complies with EN 61000-3-2: 1995+A1+A2:1998, Class D.
9. Electrostatic Discharge (ESD)
Comply with IEC 61000-4-2.
10. EFT/ Burst
Comply with IEC 61000-4-4.
11. Surge
Comply with IEC 61000-4-5.
12. Burn-In
Applying 115 Vac 10 % or 230 Vac 10% input voltage and maximum load (80%) for this
product in 40 5 C chamber.
13. M.T.B.F.
The power supply shall have a minimum mean time between failure greater than 100,000
hours Minimum (Without Cooling Fan) at continuous operation of 100% load and an ambient
temperature of 25 C.
