12v 1a /1.5a/2a/2.5a christmas tree light ac female wall adapters 

Specification :

INPUT REQUIREMENTS:

• Operating range: 90-264VAC
• Rated Input Voltage :100-240VAC
• Input Frequency Range: 50/60Hz +/-3Hz
• Input Current:0.2A max

OUTPUT REQUIREMENTS:

Output Voltage and Current 

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.

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 230VAC line input voltage (100-240 VAC),the efficiency shall be >79% at rating load.

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.

INSULATION RESISTANCE:

Primary to secondary: 10MΩ min at 500VDC. 

PROTECTION:

Short Circuit Protection
