Accuracy Calibration
Calibrating Output Voltage Accuracy
- When the module is displaying output voltage, long press the SW button to enter voltage calibration mode.
- The digital display will start flashing, indicating calibration mode is active.
- Short press the ON button to decrease the calibration value.
- Short press the SW button to increase the calibration value.
- Long press the SW button again to save the setting and exit calibration mode.
- Press the buttons multiple times to fine-tune the value.
ACalibrating Output Current Accuracy
- When the module is displaying output current, long press the SW button to enter current calibration mode.
- The digital display will start flashing, indicating calibration mode is active.
- Short press the ON button to decrease the calibration value.
- Short press the SW button to increase the calibration value.
- Long press the SW button again to save the setting and exit calibration mode.
- Press the buttons multiple times to fine-tune the value.
Notes:
- Calibration accuracy improves when the output current is higher.
- The module cannot display or calibrate output current if the current is lower than approximately 10–30 mA.
Notes & Precautions
- DC power module only. AC power is not supported.
- Do not short the output.
- IN- and OUT- must not be connected together.
- Input power must be greater than load power.
- Reduce output power if the module becomes hot.
- Rotate CV potentiometer counterclockwise if voltage adjustment is not available.
- Output current varies with load. Max output power: 3W.
- Output current is determined by the connected load and will vary accordingly.
- The module does not provide a fixed constant-current output.
- If the module becomes hot during operation, it is recommended to reduce load power or improve cooling.
Application
- DIY electronic projects
- Power supply for microcontrollers (Arduino, ESP32, etc.)
