Apply power to the Buck converter using your power supply/adapter. Make sure the green LED (4) is not lit. If it is lit press the knob (3) to turn the Buck converter off. The wattage (volts x amperage) of your power supply must be higher than the device hooked up to the output.2. Press the U/I button (2) once two adjust the voltage and twice to adjust the amperage/current. Twist the knob (3) to vary the setting in each line to match your devices specifications. To make the adjustments quicker press the knob (3) to switch digits. Press U/I again to end and it save the settings.3. Once all the settings are correct press the knob (3) to turn on the Buck converter. If you need to fine tune the voltage output twist the knob to adjust. No quick adjustment is available.4.

Product Description

Decrease or increase voltage with this Buck-Boost voltage regulator to control the output voltage to your project. This enables you to use a power supply that doesn't match the DC voltage that your DIY project needs. It also displays either the current, power, and capacity output or time of use. The display also has the ability to switch between voltage output, voltage input or board temperature.

Key Features:
  • LCD display switches between voltage output and input, output current, output power, output capacity, time of use and board temperature to keep you informed
  • Increase or decrease voltage from 5 ~ 30 VDC in to 0.5 ~ 30 VDC out to meet project requirements
  • Outputs up to 50W for power hungry small audio projects
  • Make your own 3A 30 VDC portable variable power supply with an optional battery board and 5 to 24 VDC AC power adapter
  • Plastic body frame snaps it in to a 2.92" x 1.55" (74 x 39 mm) hole for secure mounting
  • LEDs for power on and over constant current indicator
  • Over/under voltage and current protection plus temperature, time, and capacity protection
