Digital Control USB Adjustable Power Supply Module Constant Voltage Constant Current Mobile Boost Line Fan Governor 15W

Applications

Large and small power fan speed controller, USB adjustable desktop small power supply, USB adjustable charging line, router anti-blackout standby power supply, Tmall Wizard mobile power base (with charging treasure), USB adjustable boost line, Dajiang Mech Master Outdoor Battle Router Power Supply. Combined with the charging treasure, it becomes a mobile adjustable power supply, which is very practical.

Fast charge deception use

Powered by a 5V charging adapter, the input current is 4A or more to reach 15W (considering the voltage drop on the USB line and the module conversion efficiency, etc.), the ordinary 5V adapter is difficult to do, so the module adds a fast charge deception function to make the adapter output high voltage or High current. Note that you can choose to have a charger or charging treasure that supports the fast charge protocol. ! !

1. Press and hold the main button SET/M button of the dial button for more than 3 seconds to automatically enter the fast charging protocol selection interface, and the LCD will display the protocol name.

2. Press the + and - buttons of the dial button to select QC2.0, QC3.0, AFC, FCP, SCP, AUTO, and OFF. Short press SET/M button to trigger the protocol. If the trigger is successful, it will display OK, FC blue light is always on, otherwise Err is displayed, FC blue light is off. Or after selecting the protocol, pressing the SET/M button will trigger a spoofing, and then directly exit the fast charging protocol interface, and the protocol will be triggered each time it is turned on.

3. If you don't know which protocol the charger supports, you can choose AUTO mode, the module automatically chooses the spoofing protocol to match; if you don't want to use the spoof function, you can choose OFF mode.

1. Product Highlights:

• 1. Digital control adjusts voltage and current (current limit value), voltage step is 0.01V/0.1V, current step is 0.001A/0.01A, precision adjustment, accurate display.

• 2. LCD displays input voltage, output voltage, temperature, current, power, capacity statistics, time statistics.

• 3. With USB female output, easy to connect USB interface devices such as USB fan

• 4. Free screw quick terminal, push-type cable pull, no need to screw, convenient and fast.

• 5. With intelligent fast charge deception, solve the problem of insufficient power supply to the USB input port. Support mainstream fast charge protocol, QC2.0 3.0, FCP SCP AFC, you can also choose not to deceive or automatically choose 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 0-2A (wide input 4-13V, wide output 1-30V any adjustment, with short circuit protection, short circuit does not burn)

• 8. 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 (fast terminal output, USB female output, note that the two are directly connected, carefully check the output voltage before plugging in the USB device!)

2.3. Output current: 0-2A (The output current in constant voltage mode is adaptive according to the load size, it is not adjustable. If you set the limit current to 1A, then the load current is greater than 1A, it will automatically enter the constant current mode. Maximum output 1A)

2.4. Output power: less than 15W (when the output power is greater than 15W, the output is automatically turned off, the OPP is displayed, and the load power is reduced, press the ON/OFF button to solve). When the input current is too large, it may not be long-term due to temperature protection. Work at 10W or more.

2.5. Voltage display: resolution 0.01V, factory accuracy ± (0.5% + 3 words), factory calibration, no reservation customer self-calibration.

2.6. Current display: resolution 0.001A, range 0-2A, factory accuracy ± (0.5% + 3 words), factory calibration, no reservation customer self-calibration.

2.7. Power display: 0.00W-15.00W

2.8. Temperature protection: When the power component temperature is higher than 110 °C, enter the OTP protection, reduce the load power, press the ON/OFF button to solve (the power will not enter the OT protection for long-term operation within 10W, 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 the adapter with fast charge function.

2.9. Working current: about 30mA

2.10. Charging anti-backflow: Yes, it can be directly connected to the battery for charging, no need to add a diode

2.11. Short circuit protection: Yes

2.12. Weight: 64g (product net weight 42g, box 22g)

3. Function description:

Voltage and current setting method - press SET/M button, V flashes, set the voltage by short pressing or long press +, - key; press SET/M button again, A flashes, short press or long press +, - Set the current size; press the SET/M button again to exit the setting interface. If you do not operate for more than 10 seconds, the setting will be automatically exited.

Short press +, - button voltage step 0.01V, current step 0.001A; long press +, - button voltage step 0.1V, current step 0.01A.
