LM2596 3A Buck Converter LED Display 4-40V to 1.25-37V 2-Pack

LM2596 Adjustable DC-DC Buck Converter with Digital Voltmeter - 2 PackUpgrade your DIY electronics projects with our premium LM2596 Step-Down Power Supply Modules. Designed for makers, engineers, and hobbyists who demand reliability and precision.🔧 Professional-Grade PerformanceEach module features the genuine LM2596S-ADJ voltage regulator, delivering exceptional efficiency up to 92%—significantly reducing energy waste and heat generation compared to linear regulators. The robust 3A output capability (peak) handles demanding applications from motor drives to high-power LED arrays.📊 Smart Voltage MonitoringThe integrated dual-mode LED voltmeter sets this converter apart. With a simple button press, switch between monitoring input voltage (4V-40V) or output voltage (1.25V-37V). The bright 0.28-inch display offers excellent readability even in low-light workshop conditions. When precision matters, rely on the calibrated display accurate to ±0.05V.🛡️ Built-In Protection You Can TrustWe understand that your projects are valuable.
