Applications:

This module can be used in the input voltage is higher than the output voltage of the buck area, such as batteries, power transformers, DIY adjustable power supply, 24V car pen the power supply, industrial

With a voltage meter display , voltmeter error of ± 0.1V, range 4 ~ 35 V. The(Note: the input voltage is less than 4V, onboard voltage meter does not work does not show)

● Touch the key to toggle the measurement input or output voltage , and the indicator shows which terminal voltage is being measured . The initial power-on default digital display shows the input voltage, and the input indicator light is ON; touch the button, the digital tube shows the output voltage, and the output indicator OUT light. And keep the final setting, even if the power is turned on again

● The voltmeter can be turned off , long press the switch for more than 1 second and less than 4 seconds, let go can be closed . After the voltage meter is turned off, simply press the switch, you can open the voltmeter.

● input and output voltage measurement error quasi-function , long press theswitch for more than 4 seconds, let go after the voltage measurement error into the quasi-function, then IN light (calibration input), digital tube flashing display positive value (factory parameter is 0.0 ), Then press the button to change the value (range of -0.5 ~ 0.5, the unit is V), positive sign that up alignment, negative sign down calibration. Adjust the input after the more accurate value, press the button for more than 2 seconds, let go after the input error calibration, then OUT light (calibration output), and display the output of the calibration value, adjust the method and input the same, After the output of the more accurate value, long press the button for more than 2 seconds, let go after the set value and return to the normal display voltage, set the correct value immediately and power loss is not lost. (With this feature, you can meet your higher accuracy requirements)

● With terminal blocks, no soldering iron can also be used easily, and retain the wire connection point

(The input voltage must be higher than the output voltage of more than 1v)

● Maximum output current up to 3A , the recommended operating current of 2A or so, more than 2A plus heat sink

● 150KHz internal oscillation frequency, belonging to the second generation switching voltage regulator, low power consumption, high efficiency

● Input with diode protection, reverse will not burn the module

● with overheating protection and short circuit protection (more than 15W please strengthen the heat)
