The on-board voltage meter supports self-calibration mode. You only need to calibrate it once and the value will be stored
automatically. The method is as follows:
1. Hold the button for 3 seconds. Release the button to enter input voltage calibration mode (“IN”is ON) ; Hold the button for 3
seconds and release the button to enter output voltage calibration mode (“OUT” is ON); hold the button for 3 seconds, and
release the button to exit calibration mode, all parameters will be save automatically.
2. In calibration mode, click the button to adjust the value.
FEATURES
Supports self-calibration function to provide high-precision voltage output. (Recommended input voltage is maintained at 4.5V
or more)
Touch the button to switch the measurement input or output voltage, and an indicator shows which voltage is being measured.
The display can be disabled if necessary. Hold the button for 2 seconds, and release the button to turn off the display
With wire terminals, no soldering is necessary
The input voltage is 4.0 ~ 40V. (The input voltage must be 1.5V higher than the output voltage)
Continuously adjustable output voltage range of 1.25V ~ 37V. (The input voltage must be 1.5V higher than the output voltage)
The Maximum output current is 3A, it is recommended to use within 2.0A, higher currents will need a heatsink to dissipate
heat.
The output power is 20W. For more than 15W a heatsink is recommended.
The unit offers high conversion efficiency, with an average of 88%
The unit includes reverse polarity protection, overheating protection and short circuit protection
