ماژول رگولاتور DC به DC کاهنده 3 آمپر LM2596S با نمایشگر ولتاژ

Features:
1. With voltmeter display, voltmeter error ± 0.1V, range 0-40V. (Note: To ensure the accuracy of the voltmeter, please ensure that the input voltage is above 4V)
2. Tap the button to switch the measurement input or output voltage, and there is an indicator to indicate which voltage is being measured; SUNLEPHANT
3. With power-down memory function, it shows the voltage value measured last time after power-on;
4. Press and hold the button for 3 seconds to turn off the LED display. Touch the button again to turn on the LED display.
5. With terminal block, no soldering iron can be used conveniently, and retain the wire bond point
6. Input voltage 4.0-40V (the input voltage must be 1.5v higher than the voltage to be output.)
7. Adjustable output voltage range 1.25V-37V continuously adjustable (input voltage must be 1.5V higher than the voltage to be output)
8. The maximum output current can be as high as 3A, and the normal stable working current is 2A.
9. With 150KHz internal oscillation frequency, it belongs to the second generation of switching voltage regulator, with low power consumption and high efficiency.
10. The current switching indicator is red.
