Description:
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 up 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 to charge energy storage batteries.
Features:
To use the LM2596 CC/CV Regulator Module as an LED Constant Current Driver:
1. Make sure of the operating current and maximum operating voltage of the LED you will drive
2. With no load connected to the output of the module (open circuit), adjust the Constant Voltage potentiometer CV to set the output voltage to the LED maximum operating voltage.
3. Short-circuit the module output, and use a multimeter in 10A current scale to measure the output short-circuit current, and adjust the Current Potentiometer CC to set the output current to the required LED operating current.
4. Connect the LED to the module and test.
5. The module can drive multiple LEDs in series, parallel or in series/parallel strings, as long as the maximum voltage and current of the string does not exceed the 30V maximum output voltage and 3A maximum output current of the driver module.
To use the LM2596 CC/CV Regulator Module as a Battery Charger:
1. Make sure of the charging voltage and current of the battery you need to charge.
2. With no load connected to the output of the module (open circuit), adjust the Constant Voltage potentiometer CV to set the output voltage to the battery charge voltage.
3. Short-circuit the module output, and use a multimeter in 10A current scale to measure the output short-circuit current, and adjust the Current Potentiometer CC to set the output current to the expected charging current value.
4. Charge transfer lamp (CH) current default value is 0.1 times the charging current (constant current value). For lamp current adjustment, turn middle Charging Convert potentiometer adjustment.
5. Connect the module outputs to the battery and try charging.
