Product Related Product Related Description: Stable Turn Signal Current: Set at 10% of current value during charging to indicate battery fullness. High Precision Design: Utilizes dedicated IC and high-precision current-sensing resistor for stable constant current output. Temperature drift within 1% from 20°C to 100°C, ideal for LED driving. High Output Current: Supports up to 12A maximum output current. High-Frequency Capacitors: Reduces output ripple, enhancing operational stability. Applications: Ideal for high-power LED drivers Lithium-ion (or lead-acid) battery chargers Automotive power suppliers Low-voltage system power Charging 6V, 12V, 14V, and 24V batteries Battery Charging Instructions: Determine desired battery float voltage, charging current, and module input voltage. Adjust the constant voltage potentiometer to set output voltage around 5V. Use a multimeter (on 10A current range) to measure short-circuit output current. Adjust current potentiometer to achieve desired charging current. Fine-tune the constant voltage potentiometer to match the float voltage required for charging. Connect the battery and commence charging. Repeat steps 1-4 when connecting module input/output without load. LED Constant Current Drive Instructions: Determine LED operating current and maximum operating voltage. Adjust the constant voltage potentiometer to set output voltage around 5V. Use a multimeter (on 10A current range) to measure short-circuit output current. Adjust current potentiometer to achieve desired LED operating current. Fine-tune the constant voltage potentiometer to reach LED’s maximum operating voltage. Connect the LED and perform testing. Repeat steps 1-4 when connecting module input/output without load.
