●With voltmeter display, the error of the voltmeter is ±0.1V, and the range is 0~40V. (Note: If the input voltage is lower than 4V, the onboard voltmeter will not work and will not display)

● Originally touch the button to switch between measuring input or output voltage, and there is an indicator light to show which voltage is being measured, and the last setting is maintained, even if the power is turned off and on again

●Voltmeter can be turned off, press and hold the switch for more than 1 second and less than 4 seconds, and it can be turned off when you let go

●Input and output voltage measurement error calibration function, long press the switch for more than 4 seconds, after letting go, it will enter the voltage measurement error calibration function. The nixie tube flashes to display the voltage reference value (range 2.45~2.60), at this time, short press the button to change this value (circulate between 2.45~2.60). When the voltage value displayed by the voltmeter is too high, lower the reference value. When the voltage value displayed by the voltmeter is low, increase the reference value. After adjusting to the reference value you want, press and hold the button for more than 2 seconds. After letting go, save the set value and return to the normal display voltage. The set correction value will take effect immediately and will not be lost after power failure.

●With terminal blocks, it is easy to use without soldering iron, and the connection points of welding wires are reserved
Input voltage 4.0~40V (The input voltage must be more than 1v higher than the output voltage.)

●Adjustable output voltage range 1.25V~37V continuously adjustable (input voltage must be 1V higher than the output voltage)

●The output current can be as high as 3A, and the normal stable working current is 2A

●Using an internal oscillation frequency of 150KHz, it belongs to the second generation of switching voltage regulator, with low power consumption and high efficiency
