With voltmeter display and voltmeter can be self-calibrated. A more advanced voltage microprocessor is used. The error of the voltmeter is ± 0.05V and the range is 0 ~ 40V. (To ensure the accuracy of the voltmeter, please ensure that the input voltage is above 4.5V )
Touch the button to switch between measuring input or output voltage, and an indicator light shows which voltage is being measured, and save the settings, even if the power is off and then on.
The voltmeter can be turned off, and it can be easily realized by touching the left button when it is not needed.
With terminal block, it is convenient to use without soldering iron, and the welding wire connection point is reserved.
High conversion efficiency, averaged at 88% (efficiency is related to input, output voltage, current, and voltage difference)
