XL4016 vezérlő IC biztosítja a stabil működést. Többféle változat is kapható.
A modul beépítéséhez biztosítani kell a megfelelő hőelvezetést, célszerű mindig jóval túlméretezni teljesítményben, ügyelve a maximum pillanatnyi csúcsterhelésre is.!
Jellemzők:
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%). Particularly suitable for
LED driver.
3. High output current, the max output current can reach 8A.
4. Four high frequency capacitance, can lower output ripple, enhance the work stabilization.

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.)
