3X Lm2596 DC Converter Module - DC Adjustable Step Down Power Module Step Down Converter

Type: power module Model: LM2596 Step-Down Module Input voltage: 4V-35V Output voltage: 1.23 V - 30 V. Output current: 3A (maximum) Conversion efficiency: 92% (maximum) Output ripple: less than 30 mV Switching frequency: 150kHz Working temperature: -45 Celsius + 85 Power supply (3-40 V), the power indicator lights up and the module works normally. Adjust the blue potentiometer knob (usually clockwise to improve, counterclockwise to rotate down) and use a general expression to monitor the voltage required for the output voltage. Caution: As this is a step-down module, it is recommended to work for a long time with a current of less than 2.5 A and to add a heat sink (output power greater than 10 W). Maintain the minimum difference of 1.5V to ensure stable performance.
