JacobsParts XL4015 5A DC-DC Buck Step Down Voltage Constant Current Converter Module Adjustable Power Regulator Board with LED Voltmeter & USB Output

JacobsParts XL4015 5A DC-DC Buck Step Down Voltage Constant Current Converter Module Adjustable Power Regulator Board with LED Voltmeter & USB Output. Maintain stable output voltage and limit the output current over a range of input voltages. Great for general voltage conversion, battery charging, powering raw LEDs, automotive electronics, battery conversions, micro-controllers, and electronic projects. Three indicator lights let you know what is going on at a glance, a useful feature for battery charging. This module combines the high efficiency XMLSEMI XL4005 DC-DC buck converter IC with a TI LM358 Op-Amp for stable current regulation. The built in voltmeter makes for simple installation and adjustment and helps to monitor the supply or device power. The voltage and current limits are adjusted using potentiometers. A small button switches the voltmeter between input and output. Input Voltage: 5-36V DC, Output Voltage: 1.25-32V DC, Max Load: 75W/5A Peak, 50W/3.5A Sustained (whichever is lower, amps or watts), 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. Be careful with the USB port, not apply more than 5V to USB devices. Conversion Efficiency: Up to 96%, Dimensions: 68x39x15mm, XL4015 IC, 180KHz Switching Frequency.
