Description

4V - 35V DC Input voltage regulator step down converter module which has an LED display and adjustable output voltage range between 1.25 - 33V DC.

Buttons to switch measurement between the input and output voltage and to switch off the display. LED display will indicate either input or output voltage dependant on switch setting.

Input voltage must be higher than the required output voltage.

Maximum output current is 2A.

Thermal shutdown and current limit protection built in.

Ensure that you do not connect the IN+ and IN- to your power supply the wrong way round or you will burn out the module invalidating the warranty.

This small unit can be used to power any of our LED range without the need for a resistor in the circuit. Use the inbuilt voltage display to adjust the brightness of the LEDs.

You can switch between input and output voltages on the display. Press the right key to let the display show the input or output voltage. when the right "OUT" led light, it shows output, the left "IN" led show input.

Some customers report that the module cannot be adjusted, the output voltage is always equal to the input voltage. If you encounter this problem, please turn the potentiometer counter clockwise 10 turns or more, then you can adjust the output voltage because the factory default output voltage is 20V.
