Step-down Module Durable Adjustable Step-down Module LM2596 Error Voltmeter
Features:
With voltmeter display and voltmeter self-calibrating. A more advanced voltage microprocessor is used, the voltmeter error is ±0.05V, and the range is 0-40V(To the accuracy of the voltmeter, please that the input voltage is above 4.5V).
Touch the button to switch the measurement input or output voltage, and indicator light will show which channel voltage is being measured, and save the settings, even if it is powered off and then on.
When you are not using the voltmeter, you can touch the left button to turn off the voltmeter.
Input voltage 4.0-40V, 1.25V-37V output voltage range is continuously adjustable (input voltage must be 1.5V higher than the output voltage).
Output power 20W, output current 3A, it is recommended to use within 2.0A, high current or more than 15W need to strengthen heat dissipation.
High conversion efficiency, averaging 88% (efficiency related to input, output voltage, current, voltage difference).
It has overheat protection and short circuit protection, with reverse connection protection, will not burn the motherboard.
Specification:Material:
Size: Approx. 6.1x3.4x1.2cm/2.40x1.34x0.47inch
Weight: Approx. 22g
Application Range:This module can be applied to the step-down field where the input voltage is higher than the output voltage, such as battery, power transformer, DIY adjustable power supply, 24V car laptop power supply, industrial equipment step-down, 12V to 3.3V, 12V to 5V, 24V to 5V, 24V to 12V, 36V to 24V, etc.
Onboard Voltmeter Self-Calibration Method:When the on-board voltmeter displays the output voltage, press and hold the right button for 2 seconds to release, and the voltmeter and output voltage indicator OUT flash synchronously0, at this time, the output voltage adjustment mode is entered. Similarly, when the voltmeter displays the input voltage, long press the right button for 2 seconds and then release, the voltmeter and the input voltage indicator IN flash synchronously, then enter the input voltage adjustment mode.
Lightly touched the right button, the voltage rises by one unit, lightly touched the left button, the voltage is reduced by one unit. Since the voltage value of one unit is less than 0.1V, you need to press 1-5 times continuously to see the voltmeter change 0.1V, the number of consecutive key presses depends on the currently displayed voltage value. The higher the current display voltage, the less the number of presses.
After the voltage adjustment is completed, long press the right button for 2 seconds and then release, then the voltage calibration mode can be exited, and all parameter settings are automatically powered down.
Package List:1 x Module
Note:This adjustment method allows you to obtain accurate voltage values over the entire voltage range with only one calibration. This feature is designed to meet your higher accuracy requirements.
