XL4015 5A 75W High Power Step Down Convertor (CC/CV)

Overview:

The XL4015 5A 75W High Power Step Down Convertor is a power supply convertor that can regulate the current flowing through an LED array in order to maintain the desired level of light output. The module can also be used in other applications that require a regulated step-down power supply. The voltage and current can be controlled independently using the 2 onboard potentiometers

Note: Do not combine GND input and GND output connections.

Features:

• Can be used as a step-down module with overcurrent protection or LED constant current drive module
• Can be used with a variety of battery types such as lithium, nickel-cadmium nickel-metal hydride and solar powered batteries
• Lights to indicate the voltage and constant current modes
• When used as a lithium battery charger, you can set the float voltage and charge current

Specification:

• Input voltage range:4 -38VDC
• Min Input Voltage For Voltmeter: 4.5VDC
• Output voltage range:1.25-36VDC
• Output current: 0-5A
• Output power: 75W (If greater than 50W requires additional cooling)
• Voltmeter range: 4 to 40V, error +-0.1V
• Operating frequency: 180KHz
• Voltmeter Error: ±0.05V
• High efficiency up to 96%
• Built in thermal shutdown function
• Built in current limit function
• Built-in output short protection function
• Input reverse polarity protection: None (if required, high current diode in series with the input).
• Size: 61.7 x 26.2 x 15mm (LxWxH)

Instructions:

• The potentiometer closest to the input side of the board can be used to adjust the output voltage. Clockwise to increase, and anti-clockwise to decrease
• The potentiometer closest to the output side of the board can be used to adjust the constant current setting. Clockwise to increase, and anti-clockwise to decrease
• The “R” LED indicates CC or CV mode operation. If the module is operating in CV (Constant Voltage) mode the LED will be OFF, if the module is operating in CC (Constant Current) mode the LED will be ON
• The “B” and “G” LEDs indicate whether a certain amount of current is being drawn by the connected load. The load current can be adjusted with the constant current and is 10% of the constant current value. If the connected load is a battery, which will draw decreasing amounts of current as it charges, then the LEDs can indicate when charging is complete (i.e. When charge current has decreased below the preset threshold). The “B” LED will be ON and “G” LED OFF when load current is greater than the preset current value (i.e. Charging). The “B” LED will be OFF and “G” LED ON when load current is less than the preset current value (i.e. Finished charging)

Package includes:

• 1 x XL4015 5A 75W High Power Step Down Convertor
