Universal switching mode power supply. Input: AC 110V / 220V, 50 / 60Hz ; Output: DC 5V, Max 40A, 200W. The default output voltage is 5V DC, but it can be regulated by 10%, from 4.5V to 5.5V. Three sets of output channels available. It can supply with all amperage less than 40A. ---such as 1A, 8.5A, 18A, 30A, 40A. For example, if your device draws 35A, then 35A will be supplied. If draws more than 40A, only 40A will be supplied and power supply will be damaged soon. NEVER OVERLOAD! Certified by FCC CE ROHS. We focus on producing high quality power adapters. No noise, low temperature operation, no spontaneous combustion, no explosion, no fire hazard, stable output. Automatic overload cut-off, over voltage cut-off, automatic thermal cut-off, short circuit protection.

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.   Three sets of output channels The power supply has three output ports. Each port can output 40A at max. But the total power shouldn't exceed 200W. 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 4.5V to 5.5V, to make the device work better.
