LM2596 DC-DC adjustable buck module with voltmeter display with voltage accuracy calibration
Create similar products cost-effective, create a best-selling LM2596 with digital display module!!!
The LM2596 module on the market has no output short-circuit protection, and the output is short-circuited, the module is immediately damaged, and the current output capacity is less than 1.8A.
Module highlights:
1. Comfortable price, intelligent and humanized design, with high cost performance!
2. Onboard voltmeter, voltmeter can be self-calibrated, there will never be a problem of voltmeter!
Module performance and features:
● With voltmeter display and voltmeter can be self-calibrated. Using a more advanced voltage microprocessor, voltmeter error ±0.05V, measuring range 0~40V. (To ensure the accuracy of the voltmeter, please ensure that the input voltage is above 4.5V)
● Touch the button to switch the measured input or output voltage, and there is an indicator to show which voltage is being measured, and save the setting, even if the power is turned on.
● The voltmeter can be closed, which can be easily achieved by tapping the left button when it is not needed.
● With terminal, no soldering iron can also be convenient to use, and retain the welding wire connection points.
● Input voltage 4.0~40V. (The input voltage must be 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)
● Output current 3A, recommended to use within 2.0A, large current needs to strengthen heat dissipation.
● Output power 20W, more than 15W, please strengthen heat dissipation.
● High conversion efficiency, with an average of 88% (efficiency is related to input and output voltage, current and pressure difference)
● With reverse connection protection, reverse connection does not burn
● With overheating protection and short circuit protection
● Size 6.1*3.4*12cm (length * width * height)
● Weight: 22g
Scope of application:
This module can be used in the field of voltage reduction where the input voltage is higher than the output voltage, such as batteries, power transformers, DIY adjustable voltage regulator power supply, 24V vehicle pen meter power supply, industrial equipment voltage reduction, 12V to 3.3V, 12V to 5V, 24V to 5V, 24V to 12V, 36V to 24V, etc.
