LM2596 DC-DC Adjustable Buck Module with Voltmeter Display and Voltage Calibration

Size: 6.1*3.4*12cm
Weight: 22g
Create a cost-effective LM2596 module that stands out in the market and becomes a best-seller!!! Most LM2596 modules on the market do not have output short-circuit protection, and when the output is shorted, the module is immediately damaged. The current output capability is less than 1.8A! However, this module uses the original LM2596 chip with a frosted surface, output short-circuit protection, and supports a high current of up to 3A.

Module Highlights:

1.Comfortable pricing, intelligent and user-friendly design, offering extremely high cost-effectiveness!
2.On-board voltmeter with adjustable calibration for precise voltage readings.

Module Performance and Features:

?With Voltmeter Display and Calibratable Voltmeter: The module uses an advanced voltage microprocessor, with a voltmeter accuracy of ¡À0.05V and a range of 0~40V. (To ensure accuracy, input voltage should be above 4.5V.)
?One-Touch Button to Switch Between Input and Output Voltage Measurements: The indicator light shows which voltage is being measured, and the settings are saved even when power is turned off and on again.
?Voltmeter Can Be Turned Off: Press the left button to easily turn off the voltmeter when not needed.
?With Terminal Block: Can be used without a soldering iron and also retains soldering points for wiring.
?Input Voltage: 4.0~40V. (Input voltage must be at least 1.5V higher than output voltage.)
?Adjustable Output Voltage Range: 1.25V~37V, continuously adjustable. (Input voltage must be at least 1.5V higher than output voltage.)
?Output Current: 3A, recommended for use within 2.0A. For higher currents, additional cooling is required. Output power is 20W; for use above 15W, enhanced cooling is advised.
?High Conversion Efficiency: Average efficiency is 88% (efficiency depends on input/output voltage, current, and voltage difference).
?Reverse Polarity Protection: No damage if reverse polarity is connected.
?Overheat Protection and Short Circuit Protection: Provides protection against overheating and short circuits.

Application Range:

This module can be used in step-down applications where the input voltage is higher than the output voltage, such as in battery-powered systems, power transformers, DIY adjustable power supplies, 24V car laptop power supplies, industrial equipment voltage reduction, 12V to 3.3V, 12V to 5V, 24V to 5V, 24V to 12V, 36V to 24V, and more.
