AITRIP 3PCS XL4015 Step Down Module, Adjustable 5A DC-DC Buck Converter with LED Display and USB Port

• Input voltage range: DC 5-36V; Output voltage range:DC 1.25-32V adjustable
• USB output voltage is consistent with the module, not a fixed 5V output. When charging for digital equipment, make sure USB output voltage is 5V.
• it is High reliability, strong vibration resistance, good electromechanical performance.
• Input must be at least 1.5V more than the output voltage. Applying reverse polarity voltage to the input or output may damage the module.
• Application:Can use as a step-down modules with overcurrent protection, a battery charger, or a LED constant current driver module.
• Note: The module can not adjust the output voltage is always equal to the input voltage.”When you have this problem, please counterclockwise rotation of the“voltage potentiometer”10 laps or more, then use the module you can adjust the output voltage. Because the factory default output voltage of about 20V.

Specifications: Input voltage range:DC 5-36V Output voltage range:DC 1.25-32V adjustable Output current: 0-5A Output power: 75W High efficiency up to 96% Function:Built in thermal shutdown function, current limit function & output short protection function. Input reverse polarity protection: None (if required, high current diode in series with the input). Size: L x W x H =68.2×38.8×15mm Package includes:3 Pcs DC-DC Step down Module.
