Product Details

Description:

  • 1piece of DC-DC adjustable step-down power supply module
  • Input Voltage: 5-35V
  • Output Voltage: Continuously adjustable from 1.25 V to 30V
  • Rated Output Current: 3A
  • Max. Output Current: 4A (more than 15W, preferably with a heat sink)
  • Size (L x W x H): Approx. 1.9 x 0.95 x 0.5 inch / 4.8 x 2.4 x 1.3cm
  • Adjustment: Apply to 5-35V power source, use multimeter to test the oputput voltage and then adjust the potentiometer, turn clockwise to step up and counterclockwise to step down
  • Indicator Light
    • Constant current indicator(red)
    • Charging indicator(red)
    • Charged full (green)

Applications:

  • High-power LED constant current drive
  • Lithium battery charger (including ferroelectric)
  • 4V, 6V, 12V, 14V, 24V battery charger
  • Nickel cadmium, nickel metal hydride battery pack charger
  • Solar panels and wind turbines

Battery Use:

  • Make sure of the voltage and current of the battery you need to charge
  • Adjust the constant voltage potentiometer to make the output voltage same to the charge voltage
  • Potentiometer Adjustment Direction: Clockwise (increase), counterclockwise (decrease)
  • 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
  • The charge current of transfer lamp is default 0.1 times of the charging current (constant current value)
  • Connected to the battery and try to charging (for previous 5 steps, module input terminal is connected to power source, output load is NOT connected to batteries)

LED Constant Current Driver Use:

  • Make sure operating current and Max operating Voltage of the LED you need to drive
  • Adjust the constant voltage potentiometer to make sure the output Voltage is up to LED Max operating Voltage
  • 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
  • Join LED, test (For the above 3 steps, module input terminal is connected to power source, output load is NOT connected to LED)

Package Includes:

  • 1 x Adjustable Power Supply Module
