Module highlights:

1. Comfortable price, intelligent and humanized design, with ultra-high cost performance!

2. The on-board voltmeter can be self calibrated, and there will never be the problem that the voltmeter does not work!
 

Module performance and characteristics:

● with voltmeter display and self calibration. More advanced voltage microprocessor is adopted, with voltmeter error of ± 0.05v and range of 0 ~ 40V. (to ensure the accuracy of the voltmeter, please ensure that the input voltage is above 4.5V)

● touch the button gently to switch the measured input or output voltage, and an indicator light shows which voltage is being measured, and save the setting, even if it is powered off and restarted.

● the voltmeter can be turned off. When it is not needed, it can be easily realized by touching the left button.

● it can be used conveniently without soldering iron with wiring terminal, and the welding wire connection point is reserved.

● input voltage: 4.0 ~ 40V. (the input voltage must be more than 1.5V higher than the output voltage)

● adjustable output voltage range: 1.25V ~ 37V, continuously adjustable. (the input voltage must be 1.5V higher than the output voltage)

● the output current is 3a, which is recommended to be used within 2.0A. Heat dissipation needs to be strengthened for high current.

● the output power is 20W. If it exceeds 15W, please strengthen heat dissipation.

● high conversion efficiency, with an average of 88% (efficiency is related to input and output voltage, current and voltage difference)

● with reverse connection protection, reverse connection without burning

● it has the functions of overheating protection and short circuit protection

● size: 6.1 * 3.4 * 12cm (length * width * height)
 

Application scope:

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 regulated power supply, 24V on-board laptop power supply, industrial equipment voltage reduction, 12V to 3.3V, 12V to 5V, 24V to 5V, 24V to 12V, 36V to 24V, etc.
