3.1 Output Voltage Regulation
The total output voltage regulation shall be +/-5%,including the effects of line voltage variations,load current,ripple and noise,and the AC component of the load current.
3.2 Output Voltage Ripple
The switching power supply shall not exceed the following limits in the indicated voltage for 60Hz or 50Hz ripple,switching frequency ripple and noise measured with 20MHz width.
Ripple and Noise:50/60Hz Ripple + Switching Ripple and Noise
Ripple and Noise are measured at the end of output cables which are added a
0.1uF(104) Ceramic capacitor and a 22uF Electrolytic capacitor.
When 220VAC line input voltage (100-240 VAC),the efficiency shall be >82% at rating load.
5. DIELECTRIC STRENGTH (Hi-Pot) TEST:
Finished product withstands with AC3000Vrms/50Hz,5mA max,
primary to secondary, 1 minute for type test,1 second for production test.
6. INSULATION RESISTANCE:
Primary to secondary: 10MΩ min at 500VDC.
7.1 Short Circuit Protection
If short circuit occurs,all the output should be protected. After the fault, the adapter automatically recovers.
7.2 Over Shoot
The Output over shoot at turn-on shall not exceed 10% of normal voltage value with or without the load connected.
7.3 Start-up time
The start-up time is less than 2 second.
Operating temperature: 0℃ to +40℃
Storage temperature : -20℃ to +60℃
8.3 Operating Ambient Altitude
8.4 Operating at the lower temperature
At -0℃,with the rated voltage 100-240Vac charged to the primary and unloaded and full load on the secondary 8 hours, no abnormality in electric and mechanical characteristic, after 2 hours recovery at the room temperature.
8.5 Operating at the high temperature
At +40℃,with the rated voltage 100-240Vac charged to the primary and unloaded and full Load on the secondary 8 hours, no abnormality in electric and mechanical characteristic, after 2 hours recovery at the room temperature.
Cooling shall be with natural convection cooling.
The burn-in test will be performed at least 4 hours at centigrade
degrees under full load Condition.
