5A 75W DC-DC Adjustable Step-Down/Stabilivolt Power-Supply Module Voltmeter Display 61x37mm High-Power Module

1) Module performance and features: With power indicator with a voltmeter display and the voltmeter can be self-calibration. Using a more advanced voltage microprocessor, voltmeter error +/- 0.05V, range 0 ~ 40V. (Note: To ensure the accuracy of the voltmeter, please ensure that the input voltage above 4.5V) Touch the button to switch the measurement input or output voltage, and the indicator shows which circuit voltage is being measured, and save the settings, even if the power is turned on again. 2) Size 66 x 39 x 18mm / Material:Metal / Weight 33g 3) Onboard voltage meter self-calibration method: On-board voltmeter shows the output voltage, long press the right button for 2 seconds after the release, the voltmeter and the output voltage indicator "OUT" sync flashing, then enter the output voltage adjustment mode; Similarly, in the voltmeter display Input voltage, long press the right button for 2 seconds after the release, the voltmeter and the input voltage indicator "IN" sync flashing, then enter the input voltage adjustment mode; 4) Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
