New XL4016 Step-down Power DC-DC CC CV Buck Converter Supply Module,Default NO5245

Features:

Module Properties: non-isolated step-down constant current, constant voltage module (CC CV) charging module

Input voltage: DC 8-40V, Chip:XL4016

Output voltage:DC 1.25-36V continuously adjustable

Output Current: 8A (when power tube\\\'s temperature exceeds 65 degrees, please add cooling fan)

Constant current range: 0-8A ( adjustable )

Turn lamp current: constant current value * ( 0.1 ) , turn the lamp current and constant value linkage, such as constant current value is 3A, turn the lamp current is set to a constant current is 0.1 times (0.1 * 3A = 0.3A).

Lowest pressure: 1V

Output Power: Maximum power is about 300W

Conversion efficiency: up to about 95%

Operating frequency: 180KHZ

Output ripple: 20M bandwidth

Input 40V Output 36V 8A ripple around 50mV (Excluding noise)

Output short circuit for protection : Yes, constant current

Input Reverse Polarity for Protection: None

Output prevent backflow: None

Wiring: Terminal

No-load current: Typical 20mA (40V switch 36V)

Load regulation: ± 1% ( constant )

Voltage regulation: ± 1%

Dynamic response speed: 5% 200uS

Potentiometer adjustment direction: clockwise (increase) , counterclockwise (decrease). the potentiometer(CV) closed to the input voltage is used to regulate voltage, the potentiometer(CC) closed to output voltage is used to regulate current (CC)

Operating temperature: Industrial grade (-40 °c to +85 °c) ( please note the actual use of the power tube temperature , high temperature heat strengthened please )

Indicator: dual color indicator, charging indicator light is red, the green light means fully charged ( No load is green )

Size(approx): 65 x 47 x 23.5mm(L x W x H)

Applications

1. High-power LED driver

2. Lithium battery(or lead accumulator) charge

3. Vehicle-mounted power supply

4. Low voltage system power supply

5. 6V, 12V, 14V, 24V battery charge

Battery charge

1. Make sure of the battery float voltage and charging current that you need, as well as the input voltage of the module.

2. Adjust the constant voltage potentiometer and adjust the output voltage to about 5V.

3.Use the multimeter in 10A current scale to measure output short-circuit current, and adjust the current potentiometer to make the output current to the expected charging current value.

4. Adjust the constant voltage potentiometer to make the output voltage reaches the float voltage.

5. Connected to the battery, try to charge.

(1,2,3,4 steps to connect the power module input,output no-load does not connect battery.)

LED constant current drive

1. Make sure the operating current and Max operating Voltage of the LED you need to drive.

2. Adjust the constant voltage potentiometer, adjust the output voltage to about 5V.

3. Use the multimeter in 10A current scale to measure output short-circuit current, and adjust the current potentiometer to make sure the output current to the expected LED operating current.

4. Adjust the constant voltage potentiometer to make the output voltage reach the maximum LED operating voltage.

5. Connect LED, test.

(1,2,3,4 steps to connect the power module input, output No-load does not connect LED.)
