48W 12V 4A AC / DC Power Adapter

-.UL(FCC),GS(CE),PSE,KC,SAA approved -.Energy Efficient Class IV & V satisfied -,Low Tepmperature Body

This is a series of general purpose AC/DC adapters which convert 90Vac ~264Vac to astabilized DC voltage of 12V with rated output current of 4000mA.

 AC Input Voltage and Frequency : Reliable Input Voltage  : AC90-264V,Rated Input Voltage   : AC100-240V,Reliable Input Frequency  : 47-63Hz,Rated Input Frequency  : 50/60Hz

Input rated voltage,Ouput rated load. Input AC Current 1.5Amps Maximum.

Input Rated Voltage,Output no load. Maximum loss power 0.3Watts.

Input		Output Rated Voltage		Output Voltage range  (±5%)		Output Rated Current
Rated Voltage		+12.0V		11.4V ~ 12.6V		4000mA

Output voltage exceed the Rated specifications 120%-200%  into the protection.

The power supply shall protect itself from any over current condition. and shall be self-recovery when the fault condition is removed. The maximum output current shall be 120%~300% rate output current.

Shorting of output will not cause power supply to damage, or any safety hazard.The power supply shall resume normal operation after the short is removed.

The power supply has a current fuse to protect itself.

 Input 115Vac / 230Vac. and  100%,75%,50%,25% Rated Load  condition. Average efficiency (η): 87% Min.
