3PCS 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 offers a measurement error of only ± 0.1V. It accommodates 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 cease displaying). Press and hold the switch for 14 seconds to deactivate the display; a brief tap will reactivate it.
Product Advantages: Employing a second-generation, low-power, high-efficiency voltage regulation chip with an internal oscillation frequency of 150KHz, paired with premium solid capacitors, it efficiently suppresses high-frequency noise while boosting circuit stability and durability.
Convenient Operation Design: The output voltage can be readily adjusted using a miniature screwdriver. It comes with terminal blocks for rapid connections, enabling plug-and-play use without soldering.
Comprehensive Safety Protection: The input side includes dual-diode reverse connection protection, safeguarding the module from damage due to incorrect polarity. Built-in overheating and short-circuit protection are also provided (enhanced heat dissipation is recommended when power exceeds 15W).
Application Scenarios: Extensively utilized in automotive power supplies, DIY projects, industrial equipment, and other fields, addressing the varied requirements of both professional users and electronics enthusiasts
