2 Pcs LM2596 DC-DC Buck Converter 4.0-40V to 1.25-37V 2A Adjustable Voltage Regulator with LED Voltmeter Display Voltage Stabilizer Power Supply Module

About this item

• 【Precise Voltage Display and Control】This LM2596S buck converter integrates an LED voltmeter controlled by an advanced microprocessor, with an error range of ±0.05V, providing highly accurate voltage readings within the 0-40V range. The display features self-calibration and memory functions, retaining your settings even after power loss. Simple button operation allows you to instantly switch between monitoring input and output voltages, with clear LED indicators showing the current measurement status
• 【Wide Range and Stable Adjustment】This lm2596 buck converter is flexibly designed, supporting a wide DC input range of 4.0V to 40V and providing a continuously adjustable output from 1.25V to 37V, provided the input voltage is at least 1.5V higher than the output voltage. The module uses the robust LM2596 switching regulator IC, operating at 150kHz with a conversion efficiency of up to 92% and an output ripple of less than 30mV, ensuring a stable power supply
• 【Powerful Protection and Operation】This buck boost converter is designed for durability and safety, incorporating multiple built-in protection mechanisms. It features output short-circuit protection to prevent damage in case of failure; current limiting to control the output; and over-temperature thermal shutdown to protect components under high loads. Continuous use up to 2A is recommended for optimal stability and lifespan
• 【User-Friendly Design and Installation】This dc to dc buck converter prioritizes ease of use. A long press of a button allows the voltmeter to be easily turned on or off, saving energy when monitoring is not required. The module can be operated without soldering and comes with pre-soldered terminals for quick cable connection. Its compact size and standard mounting holes facilitate integration into projects, housings, or DIN rails
