SHNITPWR 12V 5A Switching Power Transformer Adapter AC 110V ~ 220V to DC 12 Volt 5amp 60W 4.5A 4A 3.5A 3A Converter LED Driver for LED Light 3D Printer CCTV Camera

Universal switch mode power supply. Input. AC 110V~220V, 50 / 60Hz; Output. DC 12V, 5A 60W max. only one input port, auto output 0~5A, default output voltage is 12V, but can be adjusted 10% between 10.8V and 13.2V. Please check the voltage of your device before use, do not overload the operation It can supply with all currents less than 5A, such as 1A, 1.5A, 2A, 2.5A, 3A, 3.5A, 4A, 4.5A, 5A. For example, if your device draws 3.8A, then 3.8A will be supplied. If draws more than 5A, only 5A will be supplied and power supply will be damaged soon. NEVER OVERLOAD ! Certified by FCC CE ROHS. We focus on producing high quality power transformers. Automatically over-current cut-off, over-voltage cut-off, over -temperature cut-off, short circuit protection. Low noise, no spontaneous combustion, no explosion, no fire hazard, stable output, safe to use. It is widely use to driving 12V LED strip light, flood light, commercial lighting project, wireless router, ADSL cats, HUB, home security cameras, audio/ video devices, 3D printer, CCTV DVR NVR Surveillance System, LCD/LED monitor screen, webcam router, speaker or other 12V devices less than 60W. There is no cooling fan in the case, silent running. Aluminum case with many holes improves heat dissipation efficiency to avoid overheating. 30 days money back, 18 months free exchange. If there is any issue, please feel free to contact us.   Input AC 110V/220V，50/60Hz Output Voltage DC 12V ( regulated by 10% , from 10.8V to 13.2V ) Output Current Max 5A Output Wattage Max 60W Professional advice （1）The max use should be no more than 80% of the full loads. Otherwise, the service life of the power supply will be greatly shortened. （2）We recommend you to use this 12V 5A 60W power supply to power devices less than 48W. Material aluminum, electronic components Safety Compliance FCC / CE/ RoHS Symbol mark L: AC Live Wire ; N: AC Neutral wire ; 〨: Ground ; +V:DC 12V+ ; -V: DC 12V- ; +VADJ: Adjust output voltage by 10% Kindly note （1） 110V/220V must be selected by switch before using to avoid damaging. （2） It comes without installation instruction, power cord, on/off switch and screws. Professional installation of licensed electrician is highly recommended. （3）High voltage inside, NEVER remove the cover. （4）Not waterproof, indoor use only. （5）If there is any issue with the power supply, Please feel free to give us your feedback. We will solve the problem for you within 12 hours.   One sets of output channel The power supply has one output port. Each port can output 5A at max. But the total power shouldn't exceed 60W. AC voltage setting The power select switch is located inside the case. Please use screw driver to reach in and change the switch to 220V for UK/EU, to 110V for USA/CA. Efficient heat dissipation Honeycomb housing can greatly improve the efficiency of heat dissipation, ensure the safe operation of the power supply and extend the service life. DC voltage adjustment You can use the knob to fine-tune the output voltage between 10% of the standard voltage, from 10.8V to 13.2V, to make the device work better.
