3PCS LM2596 Adjustable DC-DC Buck Converter with Voltmeter Display 3A

The LM2596 DC-DC adjustable step-down module features a voltmeter display with an accuracy of ±0.1V and a measurement range of 4-40V (note that the voltmeter does not work when the input voltage is lower than 4V).

The input voltage range is 2.5V-40V, with the input voltage required to be at least 1V higher than the output voltage. The output voltage is adjustable from 1.25V to 37V, with a maximum output current of 3A.

Key features of this module include low power consumption, high efficiency, overheating protection, and short circuit protection. If the power exceeds 15W, additional heat dissipation is recommended.

This voltage reduction module is suitable for a variety of applications where the input voltage is higher than the required output voltage, such as storage batteries, power transformers, DIY adjustable voltage supplies, 24V vehicle-mounted devices, industrial equipment, and more. Common use cases include step-down conversions like 12V to 3.3V, 12V to 5V, 24V to 5V, 24V to 12V, and 36V to 24V.

The module is easy to use, with wiring terminals that eliminate the need for soldering. It also includes input terminal diode protection to prevent damage from reverse connections.

The package includes 3 x LM2596 DC-DC buck converter modules with LED display, a double-sided protoboard PCB, and a jumper wire kit.
