4PCS Green LM2596 Adjustable DC-DC Buck Converter Step Down Module with LED Voltage Display, 4-40V to 1.25-37V Power Supply

Product

Specifications

: This module is fitted with a high-precision LED voltmeter that provides a measurement error of only ± 0.1V. It supports an input voltage range of 4.0V 40V and an output range of 1.25V 37V (Note: If the input voltage falls below 4V, the voltmeter will power off and stop displaying). Press and hold the switch for 14 seconds to turn off the display; a light tap will switch it back on.
Product Advantages: Employing a second-generation, low-power, high-efficiency voltage regulation chip with an internal oscillation frequency of 150KHz, combined with high-quality solid capacitors, it effectively filters out high-frequency noise while improving circuit stability and durability.
Convenient Operation Design: The output voltage can be easily adjusted using a miniature screwdriver. Equipped with terminal blocks for quick connections, it enables plug-and-play use without soldering.
Comprehensive Safety Protection: The input side features dual-diode reverse connection protection, preventing module damage in case of incorrect polarity. Built-in overheating and short-circuit protection are also included (enhanced heat dissipation is recommended when power exceeds 15W).
Application Scenarios: Widely used in automotive power supplies, DIY projects, industrial equipment, and more, meeting the diverse needs of both professional users and electronics enthusiasts
