Description: Product Description If you have any questions, please contact customer service first, do not open disputes easily, thank you! Features: 1.Comfortable price, intelligent,humane design,has a super high cost performance 2.On-board voltmeter,voltmeter can be self-calibration,there will never be a voltmeter inaccuracy problem Specifications: 1.With voltmeter display and voltmeter can be self-calibrated More advanced voltage microprocessor is used Voltmeter error ±0.05V,range 0~40V To ensure the accuracy of the voltmeter,please ensure that the input voltage is above 4.5V Touch button to switch between input and output voltage measurement And there is an indicator to show which voltage is being measured And save the setting, even if the power is off and on again 2.Voltmeter can be turned off Easy to do by touching the left button when not needed 3.With terminal block Easy to use even without a soldering iron And keep the soldering wire junction 4.Input voltage 4.0~40V (The input voltage must be at least 1.5V higher than the output voltage) 5.Adjustable output voltage range 1.25V~37V continuously adjustable (The input voltage must be 1.5V higher than the output voltage) 6.Output current 3A,recommended to be used within 2.0A High current needs to strengthen heat dissipation. 7.Output power 20W,more than 15W,please strengthen the heat dissipation 8.High conversion efficiency,88% on average (Efficiency is related to input and output voltage,current and voltage difference) 9.With reverse connection protection,reverse connection will not burn 10.With overheat protection and short circuit protection Application range This module can be used in the field of voltage reduction where the input voltage is higher than the output voltage Such as battery,power transformer,DIY adjustable voltage regulator 24 V car pencil power supply industrial equipment step-down 12V to 3.3V,12V to 5V,24V to 5V,24V to 12V,36V to 24V,etc On-board voltmeter self-calibration method 1.When the on-board voltmeter shows the output voltage,press and release the right button for 2 seconds The voltmeter and output voltage indicator"OUT"flash simultaneously Enter the output voltage adjustment mode at this time Similarly, when the voltmeter shows the input voltage Press and hold the right button for 2 seconds and then release The voltmeter and the input voltage indicator"IN"flash synchronously Enter the input voltage adjustment mode 2.Touch the right button to increase the voltage by one unit Touch the left button to decrease the voltage by one unit Since the voltage value of one unit is less than 0.1V So you need to press 1-5 times continuously to see the voltmeter change by 0.1V The number of consecutive key presses depends on the current displayed voltage value The higher the current displayed voltage,the less the number of presses; 3.After the voltage adjustment,press and hold the right button for 2 seconds and then release it At this point,you can exit the voltage calibration mode All parameter settings are automatically saved by power off Note:You only need to calibrate once to get the accurate voltage value on the whole voltage range This function is designed to meet your higher precision requirements,please feel free to use it Package includes: 1*DC-DC adjustable buck module Note: Only the above package is included Specifications are manually tested and are for reference only Please refer to the actual product,thank you About Us We accept all payments authorized by eBay. powered by
