Indicators LM2596 DC-DC Step Down CC CV :

• CC/CV Red LED: Charging in constant current mode
• CH Blue LED: Fully charged
• OK Red LED: Charging in Constant Voltage Mode
• Output short circuit protection: Yes, constant current (constant current value of the current settings)
• Input reverse polarity protection: No, please comply with input voltage specifications or place an input reverse polarity protection diode in series.
• Connection mode: Soldered

Applications of LM2596 DC-DC Step Down CC CV :

• Make sure of the charging voltage and current of the battery you need to charge.
• With no load connected to the output of the module (open circuit), adjust the Constant Voltage potentiometer CV/OK to set the output voltage to the battery charge voltage
• Short-circuit the module output, and use a multimeter in 10A current scale to measure output short-circuit current, and adjust the Current Potentiometer CC to set the output current to the expected to charge current value.
• 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 Light potentiometer adjustment;
• Connect the module outputs to the battery and try charging.

Package Include:

• 1x LM2596 CC/CV Regulator Module as an LED Constant Current Driver
