Numerical control USB adjustable power supply 2A/15W (precise adjustment of voltage and current numerical control) Support free customization, appearance design, and logo can be added. Applications: large and small power fan governor, USB adjustable desktop small power supply, USB adjustable charging cable, router anti-power outage backup power supply, Tmall Genie mobile power base, DJI Mecha Master outdoor battle router power supply, USB adjustable boost cable, combined with power bank, it is very practical to use a variety of mobile use adjustable power supply. Powered by a 5V charging adapter, the output of the module above 4A can reach 15W (considering the voltage drop on the USB line and the conversion efficiency of the module, etc.). It is difficult for ordinary 5V adapters to do so, so the module has added a fast charging inducing trigger function, which can induce the adapter to output high voltage or high current. Pay attention to choosing a charger or power bank that supports the fast charging protocol, this product can be successfully deceived!!! The use of fast charging deception: 1. Long press the main key SET/M button of the dial button for more than 3 seconds, automatically enter the fast charging protocol selection interface, and the LCD screen will display the protocol name. 2. Short press the + and - buttons of the dial button, and select QC2.0, QC3.0, AFC, FCP, SCP, AUTO, OFF. Short press the SET/M button to trigger the protocol. If the trigger is successful, OK will be displayed, FC blue light is always on, otherwise Err will be displayed, and FC blue light will be off. Or after selecting the protocol, keep pressing the SET/M button to trigger a trick, and then directly exit the fast charging protocol interface. The protocol will be triggered every time it is powered on in the future. 3. If you don't know which protocol the charger supports, you can choose the AUTO mode, and the module automatically selects the deception protocol for matching; if you don't want to use the deception function, you can choose the OFF mode. 1. Baby Highlights: 1. The numerical control sets the voltage and current (limit viewership of value), the voltage step 0.01V/0.1V, the current step 0.001A/0.01A, precise adjustment, accurate display. 2. LCD display input voltage, output voltage, temperature, current, power, capacity statistics, time statistics. 3. With USB female output, it is convenient to connect USB fans and other USB interface devices 4. Screw-free quick wiring terminals, press-type wiring, no need to screw, convenient and fast. 5. With intelligent fast charging deception to solve the problem of insufficient power supply from the USB input port. Support mainstream fast charging protocols, QC2.0 3.0, FCP SCP AFC, and can also choose not to deceive or automatically select the deception mode. 6. High power 15W, 2A current, can be used for fan speed regulation, desktop power supply, adjustable charger, router power supply, etc. 7. Adjust the output voltage arbitrarily, limit the current to 0-2A (wide input 4-13V, wide output 1-30V can be adjusted arbitrarily, with short circuit protection, short circuit does not burn) 8. Use as a USB charging cable, adjust the charging voltage and maximum charging current arbitrarily (any voltage, with constant current, anti-backflow, to meet the charging of most batteries) 9. Multiple protection (short circuit, over current, over temperature, over power, over voltage protection, charging anti-backflow protection)     2. Product parameters: 2.1. Input voltage: 4-13V (USB male, MicroUSB, TYEPE-C 3 input interfaces) 2.2. Output voltage: 1-30V (quick terminal output, USB female output, note that the two are directly connected, carefully check the output voltage before plugging into the USB device!) 2.3. Output current: 0-2A (the output current in constant voltage mode is adaptive according to the load size and is not adjustable. If you set the limit current to 1A, then when the load current is greater than 1A, it will automatically enter the constant current mode, and the maximum output is 1A) 2.4. Output power: less than 15W (when the output power is greater than 15W, automatically turn off the output and display OPP. After reducing the load power, press the ON/OFF key to solve the problem). When the input current is too large, it may not work for a long time due to temperature protection above 10W. 2.5. Voltage display: resolution 0.01V, factory accuracy ± (0.5% + 3 words), factory calibration, no reservation for customer self-calibration. 2.6. Current display: resolution 0.001A, range 0-2A, factory accuracy ± (0.5% + 3 words), factory calibration, no reserved customer self-calibration. 2.7. Power display: 0.00W-15.0W 2.8. Temperature protection: When the temperature of the power component is higher than 110 ° C, enter OTP protection. After reducing the load power, press the ON/OFF key to solve the problem (long-term operation of power within 10W generally does not enter OT protection. When the input current is greater than 3A, it may enter over-temperature protection when working for a long time. Even if it does not reach 15W, it is recommended to use an adapter with fast charging function) 2.9. Working current: about 30mA 2.10. Charging and anti-backflow: Yes, it can be directly connected to the battery for charging without adding a diode. 2.11. Short circuit protection: Yes 2.12. Weight: 64g (product net weight 42g, packaging box 22g)   3. Function description:   Voltage and current setting method - short press the SET/M button, V flashes, and set the voltage size by short press or long press the + and - keys; press the SET/M button again, A flashes, and set the current size by short press or long press the + and - keys; press the SET/M button again to exit the setting interface. If it does not operate for more than 10 seconds, it will automatically exit the setting. Short press +, - button voltage step 0.01V, current step 0.001A; long press +, - button voltage step 0.1V, current step 0.01A.
