  • Stable constant current with a dedicated IC and high-precision resistor, minimal temperature drift.
  • High output current, up to 8A max.
  • Four high-frequency capacitors reduce output ripple and enhance stability.
  • Double heat sink for efficient heat dissipation.
  • Improved working efficiency and reduced heat with large Sendust Core and pure copper wiring.
  • 3296 multiturn potentiometer for accurate voltage and current regulation.
  • Dual color lamp for clear working condition indication.
  • Adjustable voltage and current settings with excellent performance.

Applications

  • High-power LED driver
  • Lithium battery or lead accumulator charging
  • Vehicle-mounted power supply
  • Low voltage system power supply
  • Battery charging for 6V, 12V, 14V, 24V
  • On-board laptop power supply
  • Regulated power supply
  • Low voltage power supply system

Battery Charging Instructions

  • Confirm the required battery float voltage, charging current, and module input voltage.
  • Set the output voltage to around 5V using the constant voltage potentiometer.
  • Measure the output short-circuit current using a multimeter in the 10A current scale, adjust to desired charging current.
  • Adjust the constant voltage potentiometer to achieve the float voltage.
  • Connect the battery and begin charging (Steps 1-4 require the power module to be connected, no-load for output).

LED Constant Current Drive Instructions

  • Identify the desired LED operating current and maximum operating voltage.
  • Set the output voltage to around 5V using the constant voltage potentiometer.
  • Measure the output short-circuit current and adjust to the desired LED operating current.
  • Adjust to the maximum LED operating voltage using the constant voltage potentiometer.
  • Connect the LED for testing (Steps 1-4 require power module input connection, no-load for output).
