- ¸ðµ¨ ¹øÈ£: 5A high power 75W
- ±Ù¿ø: CN (Á¤Ç°)
Features:
1. With voltmeter display, the voltmeter error is ± 0.1V, and the range is 4 ¢¦ 48V. (Note: the input voltage is lower than 4V, the onboard voltmeter does not work and does not display)
2. Large volume 5 * 5 touch the button to switch between measuring input or output voltage, and an indicator light shows which terminal voltage is being measured. By default, the digital tube displays the input voltage and the input indicator IN is on. When the button is touched, the digital tube displays the output voltage and the output indicator OUT is on. And keep the last setting, even after power off
3. The voltmeter can be turned off. Press and hold the switch for more than 1 second and less than 4 seconds. After the voltmeter is turned off, just press the switch briefly to turn on the voltmeter.
4. The input and output voltage measurement error calibration function, long press the switch for more than 4 seconds, and enter the voltage measurement error calibration function after releasing the hand. At this time, the IN light is on (calibrating the input terminal), and the digital tube flashes to display a more positive value (factory parameter is 0.0). At this time, you can change this value by pressing the button shortly (the value range is -0.5 ¢¦ 0.5, the unit is V). A positive number indicates upward calibration, and a negative number indicates downward calibration. After adjusting the calibration value of the input terminal, press and hold the button for more than 2 seconds, and enter the error calibration of the output terminal after releasing. At this time, the OUT light is on (calibrating the output terminal), and the calibration value of the output terminal is displayed. The adjustment method is the same as that of the input terminal. After the calibration value at the output end, press and hold the button for more than 2 seconds, and save the set value and return to the normal display voltage after letting go, the set correction value will take effect immediately and will not be lost after power failure. (With this function, you can meet your higher accuracy requirements)
5.With terminal block, it is convenient to use without soldering iron, and the welding wire connection point is reserved
(The input voltage must be more than 1v higher than the voltage to be output)
6. The maximum output current can be as high as 5A, and the recommended working current is about 4A.
Module usage tutorial:
1. The input and output voltage measurement error is more accurate: press and hold the switch for more than 4 seconds, and the voltage measurement error comparison function is entered after releasing the hand. At this time, the IN light is on (calibrating the input end), and the digital tube flashes to display a more positive value (the factory parameter is 0.0 ), At this moment, press this button to change this value (the value range is -0.5 ¢¦ 0.5, the unit is V), positive number means upward calibration, negative number means downward calibration. After adjusting the calibration value of the input terminal, press and hold the button for more than 2 seconds, and enter the error calibration of the output terminal after releasing. At this time, the OUT light is on (calibrating the output terminal), and the calibration value of the output terminal is displayed. The adjustment method is the same as that of the input terminal. After the calibration value at the output end, press and hold the button for more than 2 seconds, and save the set value and return to the normal display voltage after letting go, the set correction value will take effect immediately and will not be lost after power failure. (With this function, you can meet your higher accuracy requirements)
2. Turn off the voltmeter: long press the switch for more than 1 second and less than 4 seconds, you can turn it off with a loose hand. After the voltmeter is turned off, just press the switch briefly to turn on the voltmeter.
