 INPUT REQUIREMENTS:

• Operating range: 90-264VAC
• Rated Input Voltage :100-240VAC
• Input Frequency Range: 50/60Hz +/-3Hz
• Input In-rush Current: 30A max
• Input Current: 800mA max 

OUTPUT REQUIREMENTS:

Output Voltage and Current

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.Output Voltage Regulation 

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.

EFFICIENCY:

When 120VAC line input voltage (100-240VAC),the efficiency shall be >79% at rating load.

DIELECTRIC STRENGTH (Hi-Pot) TEST:

Finished product withstands with AC 3000Vrms/50Hz,5mA max,

primary to secondary, 1 minute for type test,1 second for production test.
