Voltage display adjustable buck module DC / DC power module Features:
1. With a voltmeter shows that the voltmeter error ± 0.1V, range 0-40V. (Note: To ensure the accuracy of the voltmeter, please ensure that the input voltage above 4V).
2. Touch the button to switch the measurement input or output voltage, and the indicator shows which voltage is being measured.
3. With power-down memory function, after power on the last measured voltage value that way.
4. Long press the touch button for 3 seconds to turn off the LED display, touch the button again to open the LED display.
5. With terminals, no iron can also be easy to use, and to keep the wire bonding point.
6. Input voltage 4.0-40V (input voltage must be higher than the output voltage to be more than 1.5v.)
7. Adjustable output voltage range 1.25V-37V continuously adjustable (input voltage must be higher than the output voltage of about 1.5V).
8. The maximum output current up to 3A, normal and stable operating current at 2A.
9. Using 150KHz internal oscillation frequency, belonging to the second generation switching voltage regulator, low power consumption, high efficiency.
With overheat protection and short circuit protection. Specifications:
