## Description

Features: - DC-DC step-down module - Thickened circuit boards - Advanced solid-state capacitor - Short circuit and over-temperature protection - 100% tested, sealed in anti-static packaging Kindly Note: 1. Input voltage must be 1.5 V higher than the output voltage, no boost 2. Do not reverse the input and output interface 3. Keep output under 2A (or 15W), and use a heat sink when for a long time working How to Calibrate the Digital Tube Voltmeter (Optional steps for the person who need a highly accurate voltage value) 1. Short press the left "ON/OFF" button to start up the digital tube voltmeter. Long press(>1s, 4 seconds) the left button to enter self-calibration of voltage measurement(calibration range: -0.5-0.5V, factory setting is 0.0). "IN" indicator lights = input voltage measurement calibration starts. Then, long press(>2 seconds) the right "Mode" button, "OUT" indicator lights = output voltage measurement calibration starts. Tap the left / right button to reduce / rise by one unit (since the voltage value of one unit is less than 0.1V, you need to 1-5 times tap the button continuously, so that the voltmeter can change by 0.1V) 3. After calibration, long press(>2 seconds) the right "Mode" button to preserve the adjusted value(no loss with outage) and back to normal voltage display. Specifications: - Model: LM2596 / Digital Tube Voltmeter - Input voltage: DC 4V - 40V - Output Voltage: DC 1.5V - 35V (adjustable) - Output Current: 3A (max.) - Conversion Efficiency: 92% (max.) - Switching Frequency : 150KHz - Operating Temperature: -45℃ to +85℃ - Size(L x W x H): 57*36*13mm - Weight: 21g Package List: 2x DC-DC Buck Converter Module with LED Display
