DC DC 4 40V Adjustable Converter Module Step Down Voltage Regulator

Product information1. Press the button to change the measurement input or output voltage, and the indicator light shows which voltage is measured, and keep the last setting even if it is turned off and on again.2. The voltmeter can be turned off by pressing and holding the switch for more than 1 second and less than 4 seconds.3. With the terminal block, no soldering iron can be used conveniently and the wire connection point is retained. The input voltage is 4.0~40V (the input voltage should be higher than the voltage to be output by more than 1V.).4. Adjustable output voltage range from 1.25V to 37V continuously adjustable (the input voltage should be higher than the voltage to be output by more than 1V).5.The maximum output current can reach 3A and the common stable working current is 2A.Specification:Features:With voltmeter display, voltmeter error ±0.1V, range 0~40V.Press the button to change the measuring input or output voltage, and the indicator light shows which voltage is measured and keep the last setting, even if it is turned off and then on.The voltmeter can be turned off by pressing the switch and switching holding it down for more than 1 second and less than 4 seconds. With the terminal block, no soldering iron can be used conveniently and the connection point of the wires is retained.This time, the indicator light is on (calibration input terminal) and the digital tube flashes to display the correction value (the factory setting is 0.0) this time, press the button to change this value (the value range is -0.5~0.5, the unit is V), the positive number means upward calibration, and the negative number means downward calibration. After adjusting the comparison value of the input end, press and hold the button for more 2 seconds, then release the error calibration after release, then the output indicator light is on (calibration output) and the calibration value of the output is displayed.The adjustment method is the same as the input. After the comparison value at the end of the output, press and hold the button for more than 2 seconds. After releasing your hand, save the set value and return to normal display voltage.The set correction value takes effect immediately and power is not lost.Note:Input voltage is lower than 4V, on-board voltmeter does not work and does not display.SpecificationsWidth10cmHeight10cmWeight0.1kgColorBlackRef.
