1. With the voltmeter shows voltage meter error ± 0.1V, the range 0-40V. (Note: To ensure the accuracy of the voltmeter, please ensure that the input voltage of 4V and above) 2. Touch the key to switch measuring input or output voltage, and has a light show which is being measured voltages 3. Power off memory function, show that road after power voltage values measured for the last time 4. Press the touch button for 3 seconds to turn off LED display, touch the button again to turn on the LED display 5. The band terminals, no iron can also be easy to use, and retention wire connection point 6. Input voltage 4.0-40V (input voltage to the output voltage must be higher than 1.5v.) 7. The adjustable output voltage range of 1.25V-37V continuously adjustable (input voltage must be higher than the output voltage to a high of about 1.5V) 8. The maximum output current up to 3A, normal and stable operating current of 2A 9. the internal oscillation frequency 150KHz, belonging to the second generation of switching voltage regulator, low power consumption, high efficiency 10. The current switching LEDs are red
Delivery was very fast.
The product corresponds to the description.
Quality is very good.
The module works excellent and reliable.
The output voltage remains constant even when the load changes.
Have bought and processed these modules several times.
To date, I have never had any problems or failures.
Am very satisfied with this product.
I will be buying more of these modules in the future.
I can highly recommend a purchase.
