Dual Display 5A Power Adjustable Step-Down Constant-Voltage Constant-Current Power Module （With Case)
Calibration: This module has a calibration function, don’t worry about the problem of inaccurate measurements. If you find inaccurate measurement, can use the following method of calibration. Just for the first time using a calibrated one! Voltage Calibration: when power off status, keep pressing the “set” key. power on, and enter the voltage calibration mode. then the LCD screen starts flashing. release the “set” key, press the “Set” button to increase, and press the “ENT” button to reduce, until calibrated to the correct input voltage. For example, the input voltage is 12.65V, then the voltage was adjusted to 12.65V. then automatically saved after 2 seconds, power off, and calibration is complete! Special Instruction: Some customers feedback that the output voltage of the module can not be adjusted When they just receive the item, this is because the module factory defaults the output voltage at about 20V. When you encounter this problem. Please counterclockwise rotation ADJ-V potentiometer 10 laps or more, until the voltage value changes, then the module can properly adjust the voltage. Setting Instruction: Setting key to set the display node, has three types: 1, F-0 mode: Display output voltage: 2, F-1 node: Display input voltage: 3, F-2 mode: Alternating display input or output voltage Instructions: Press the “SET” button to cycle through the three display modes, the corresponding indicator will be on or off, then press the “ENT” button to save and exit. if separate press the ‘ENT” button to switch the backlit LCD screen. Using Instructions: Adjusting Voltage: under no-load conditions, adjust the “constant voltage potentiometer ADJ-V”, so that the output voltage reaches the value you want: Adjustment Current: connected to the load, adjust the “constant current potentiometer ADJ-I”, so that the output current reaches the current value you want (the factory default is more than 2A, if you want to adjust the current value is small. more counter-clockwise tune laps will change), if you do not need constant current, it doesn’t need adjustment: Indicator color change instruction: Charge turn lamp current factory default is 0.1 times the charging current: battery during charging. the current is gradually reduced, gradually turned from the constant current charging to constant voltage charging, if the charging current setting is IA, then when the charge current is less than 0.1A. the charging yellow indicator light is off, the full blue indicator lights up and the battery is fully charged.

Features:
- Wide input voltage: 5-40VDC; Output voltage: 5-36VDC; The maximum output current is 8A; The maximum output power is 150W
- The module adopts the deliciated crystal shell and the LCD digital display, can full-screen display voltage and current; surrounded by a hollow design, good for heat dissipation
- The conversion efficiency is up to 95%; the operating temperature: is -40 ~ +85 degrees
- With the calibration function and short-circuit protection, easy to operate; the shell floor has a fan opening, can add a fan to strengthen the heat dissipation
- Widely suitable for direct drive LED, solar panels, wind turbines, etc.
Package Includes:
1 x Dual Display 5A Power Adjustable Step-Down Constant-Voltage Constant-Current Power Module.( with case )Setup Guide
1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
