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
