Input Characteristics:
1) Input voltage range (90~264Vac)
Nominal/Rated: 110/220V
2) Frequency: The input frequency range will be 47HZ to 63HZ
3) Input Current: The input current will not exceed 0. 5Amp(rms. )for 90Vac
4) Efficiency: The adapter effciency (watts output/watts input)will be
More than65%typically at full load condition at 110Vac. (After warm-up 30min. )
5) Hold Up Time: The output hold up time will be greater 5msec.
At 110Vac/60HZ, 25degree C ambient temperature, full load.
6) Input Current (cold start): At 220Vac, 50Amp max (test equipment S-101)

Output Characteristics:
1) DC load Characteristics:
Load range Nominal/Rated: 1A
Regulation: 4. 75-5. 25V
2) Ripple and Noise Test:
I. Use 20MHz Bandwidth Frequency Oscilloscope.
Ii. Add 0. 1 uf and 470 uf Capacitors at output cpnnector terminals
For ripple and Noise test.
Iii. Ripple with spike noise <=120mV.
Iv. Test Condition: Input rated voltage and output rated load
3) Overshoot: The adapter use in overshoot at turn on turn off AC input
Will be less than 10%of the nominal value and will decay to within the
Regulation band in less than 50m sec.

Protection
1) Primary (input) Protection: The input power line will be fused with a fuse 1A,
250Vac
2) Secondary (output) Protection:
I. Over Current (OC) Protection
When an internal fault occurs, or an external fault is applied to the adapter,
Such that an overload or short circuit is applied to the output, the adapter
Will be shut-down. Adapter latch is not allowecd.
Ii. Short Circuit Protection
The adapter will protect itself, and shut down, if a short circuit is applied
Between DC return and the output. This condition will cause no damage
To adapter. Adapter latch is not allowed.

Power Supply Sequencing
1) AC Power On: When proper AC power is applied, the output will
Reach its regulation limits within 3. 0 second.
2) The output rise time (measured from the 10%point to the 90%point
On the Waveform) will be between with 1 ms and 50 ms.

Safety Characteristics:
1) Safety Approval SEE THE LABEL
3) Insulation Resistance: The resistance of the insulation between
The power terminal and the eatth Groun contact is more than 3M ohms
While wishstanding a voltage of 500VDC.
3) Withstanding voltage:
Primary to Ground 1500Vac or 2121Vdc for 3 sec.
Primary to Secondary 3000Vac or 4242Vdc for 3sec.
The condition: At leakage current 10mA scale
4) Leakage Current: The adapter leakage current is less than 750uA
At rated voltage *1. 06=5/-0V and rated frequency.

Envieonment
1) Operating temperature
I. The adaoter operating temperature is 0 to 40 degrees centigrade.

Ii. The adaoter storage humidity 20 to 90 prcent centigrade.
Iii. The adapter storage day: Less than 210 days avoid affecting its life.
3) Vibration and Shock
No evidence of any mechanical or functional damages after the vibration
And shock testing. (meet Item 1~8 test)
*Shipping Vibration: The AC adapter may be vibrated in three mutually
Perpendicular Axes of 0. 5mm displacement peak to peak at 2 to 55 to 2Hz,
7minutes per cycle for a duration of 30 minutes.
*Shipping Shock: The AC adapter in the shipping package may be duopped
8 times from Aheight of 900mm.

Life
1) On-Off Life: To verify the power supply wishstand 5, 000 time
On-off repetition of primary power without failure or damage at 90 Vac input.
2) Operational life: The adapter will be desugned for a minimun life of
100, 000hrs power-on Hours at 25 degeees ambient temperature.
3) Burn-in: 100% burn-in test at 80~100% of ful load at 35~45 burn-in room,
72hrs test for prototype samples, 24 hrs test for pilot run samplesfor,
4hrs test for mass production.
