SHNITPWR 12V DC Power Supply 50A 600W Regulated Switch Power Transformer AC 110V 220V to DC 12 Volt 50amp 48A 45A 42A 40A Converter Adapter LED Driver 3 Output Port for LED Light 3D Printer CCTV

Universal switching mode power supply. Input: AC 110V / 220V, 50 / 60Hz ; Output: DC 12V, Max 50A 600W. Three output ports. Each port outputs 0~50A automatically to match your device, 50A max in total for 3 ports. The default output voltage is 12V, but it can be regulated by 10%, from 10.8V to 13.2V. It can supply with all currents less than 50A, such as 5A, 10A, 15A, 20A, 30A, 40A, 42A, 45A, 48A, 50A. For example, if your device draws 35A, then 35A will be supplied. If draws more than 50A, only 50A 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 600W. Considering large power and safety, we build in a cooling fan to improve heat dissipation efficiency. The fan will keep running all the time once it is powered. 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 50A Output Wattage Max 600W 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 50A 600W power supply to power devices less than 480W. Material aluminum, electronic components Safety Compliance FCC / CE/ RoHS Symbol mark L: AC Live Wire ; N: AC Neutral wire ; 〨: Ground ; +V:DC 12V+ ; COM: 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 24 hours.   Three sets of output channels The power supply has three output ports. Each port can output 50A at max. But the total power shouldn't exceed 600W. 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 There is built-in cooling fan, which makes heat dissipation more efficient. 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.
