1. Designed with a voltmeter, the voltmeter error is ± 0.1 V, measurement range of 5 V ~ 35 V
2. The switch changes the measurement of the input or output voltage, and there is an indicator light that shows which voltage is being measured
3.
4. The maximum output current can be up to 4A; It is recommended that the working current be approximately 2A, and please add a heat sink if it exceeds 2A.
5. With an internal oscillation frequency of 400 kHz, these belong to the second generation of switching voltage regulators, featuring low power consumption and high efficiency.

Features:
Developed with a voltmeter, the voltmeter error is ±0.1V, and the measurement range is 5V~35V.
Tactile touch switches change the input or output voltage measurement, and there is an indicator light that shows which voltage is being measured.
The input and output have screw terminals for easy connection, even without a soldering iron, and a solder pad for soldering.
The maximum output current can be up to 4A; It is recommended that the working current be approximately 2 A and that a heat sink be added for currents exceeding 2 A.
With an internal vibration frequency of 400 kHz, these are second-generation switching voltage regulators, featuring low power consumption and high efficiency.
Widely used for memory batteries, performance transformers, adjustable controlled power supplies, industrial plants, 9-12 V, 12 V-18 V, 18 V-24 V, etc.

Instructions:
1. When switched on for the first time, the default display shows the input voltage and the input indicator lights up. Press the button, and the button will display the output voltage and the output indicator will light up. The last setting is saved, even if the device is switched off and restarted.
2. Press and hold the button for more than 4 seconds, then release it to perform voltage measurement error calibration. The display will illuminate (input voltage calibration) and the display will flicker with the calibration value (the default is 0.0). Press the button to change this value (ranging from -0.5 V to 0.5 V). To view the input voltage calibration value, press and hold the button for more than 2 seconds, then release it to access the display. to the output voltage error calibration function. The display lights up (output voltage calibration), and the method for setting the display calibration value is the same as for setting the input. After setting, press and hold the button for more than 2 seconds, then release it to save the set value and return to the normal voltage display. The calibration value is activated immediately and saved in the event of a power failure. (This function can provide greater accuracy)
3. Turn off the voltmeter: Press and hold the switch for more than 1 second and less than 4 seconds, then release it to turn off the voltmeter. The voltmeter will turn on when you press the switch after turning it off.
A:
1. If the input voltage is less than 4.5V, the voltmeter will not function and will not display a reading.
2. The input voltage must be at least 1V higher than the input voltage. Output.
3. With an output exceeding 20W, a heat sink is recommended to improve heat dissipation.
4. If the output voltage remains constant and cannot be set, please turn the potentiometer more than 10 revolutions clockwise; the voltage should then be set normally.
5. Please note that the new and old types of this product will be sent randomly, so please ensure this is acceptable before ordering.
