XL4016 CC-CV Converter

Features:

• 1. Fixed turn lamp current is 0.1 times the current value ( Used to identify whether the battery is fully charged When charging).
• 2. Made from a dedicated benchmark IC and high-precision current sensing resistor, proving a more stable constant current, (when 20 °c to 100 °c constant current 1A, temperature drift less than 1%).
• 3. High output current, the max output current can reach 8A.
• 4. Four high frequency capacitance, can lower output ripple, enhance the work stabilization.

Specifications:

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.
• 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.)
