PartNumber: DC012-LM2596-CC-CV

Release Date: 10-03-2018

Details: Scope of application: Battery use: 1. Identify the voltage and current of the battery you need to charge 2. Adjust the constant voltage potentiometer to make the output voltage same to the charge voltage 3. Potentiometer Adjustment Direction: Clockwise (increase), counterclockwise (decrease) 4. 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 5. The charge current of transfer lamp is default 0.1 times of the charging current (constant current value) 6. Connected the battery and start charging, while charging for the first time do not connect load. Note: While Charging Lithium ion batteries if the lithium ion battery voltage is low. If use the constant voltage charging directly. Due to high pressure the battery may damage. So to mitigate that risk the module has a built-in feature to use the constant current charging at low levels and the automatic switch back to the constant voltage charging once the battery reaches saturation level. LED Constant Current Driver Use: 1. Make sure operating current and Max operating Voltage of the LED you need to drive. 2. Adjust the constant voltage potentiometer to make sure the output Voltage is up to LED Max operating Voltage. 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. Join LED and test (For the above 3 steps for caliberating the module, module input terminal is connected to power source, output load(LED) not connected).
