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. Technical Specifications: Module Type: Non-isolated buck constant current constant voltage (CC CV) charging module Input Voltage: DC 7-32V Output Voltage: DC 0.8-28V (adjustable) Output Current: 9A to 12A (if MOSFET temperature exceeds 65°C, use cooling fan) Constant Current Range: Adjustable from 0.2A to 12A Turn Signal Current: 0.1 times the current setting Minimum Voltage Drop: 1V Output Power: Up to approximately 300W Conversion Efficiency: Up to 95% Operating Frequency: 300kHz Output Ripple: Typical 50mV (excluding noise) Short Circuit Protection: Yes, constant current Reverse Polarity Protection: None Backflow Prevention: None Wiring Method: Terminal connection No-load Current: Typical 20mA (24V input, 12V output) Load Regulation: ±1% (steady state) Voltage Regulation: ±1% Dynamic Response: 5% within 200µs Potentiometer Adjustment: Clockwise to increase, counterclockwise to decrease Operating Temperature: Industrial grade (-40°C to +85°C) Indicators: Dual-color (red during charging, green when fully charged; green with no load) Dimensions: Approximately 65 x 47 x 22mm (length x width x height) Package Contents: 1 x DC-DC Buck Converter Module Shipping Our shipping cost includes the cost of the packaging box, the materials used to protect the product and/or all other materials used during the processing of the product, residential shipping fee, and handling fee.
