Step Down Voltage + Current Buck Converter Charger LM2596 3A **LOCAL STOCK**

DC-DC Step Down Adjustable Voltage & Constant Current Driver/Battery Charger:

Specifications:

Input Voltage: 7 - 35V DC
Output Voltage: Continuously adjustable from 1.25 - 30V DC
Output Current: Adjustable constant current 0.3 - 3A Max (Use a Heat sink when at 3A for better heat dissipation)
Output Power: 15W
Switching Frequency: 150KHz

This LM2596 Constant Voltage / Constant Current (CC/CV) regulator module is a very flexible and adaptable charging solution that can provide either a Constant Voltage (CV) or Constant Current (CC) output.

With a variable output voltage range of 1.25V to 30V and variable output current from 0A to 3A, it is ideal for use as an LED or laser diode current source/driver, a battery charger, a lab current/voltage source, or to regulate the output of solar panels or wind turbines to charge energy storage batteries.

It can charge most any size lithium ion cell to almost any voltage you need. This is an inexpensive way to charge those 4.30V and 4.35V cells, as well as LiFePo and many other cells that require different termination voltages. It is also a good way to charge smaller cells since you can almost infinitely adjust the charging current and output voltage.

Applications:

- High-power LED constant current drive
- Lithium battery charger (including ferroelectric)
- 4V, 6V, 12V, 14V, 24V battery charger
- Nickel cadmium, nickel metal hydride battery pack charger
-Solar panels and wind turbines


Battery Use:

Make sure of the voltage and current of the battery you need to charge
Adjust the constant voltage potentiometer to make the output voltage same to the charge voltage


Potentiometer Adjustment Direction:

Clockwise (increase), counterclockwise (decrease)
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 charging current value
The charge current of transfer lamp is default 0.1 times of the charging current (constant current value)
Connected to the battery and try to charging (for previous 5 steps, module input terminal is connected to power source, output load is NOT connected to batteries)


LED Constant Current Driver Use:

Make sure operating current and Max operating Voltage of the LED you need to drive
Adjust the constant voltage potentiometer to make sure the output Voltage is up to LED Max operating Voltage
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
Join LED, test (For the above 3 steps, module input terminal is connected to power source, output load is NOT connected to LED)
