Operating Notes:

As with any DC-DC converter, the input DC power supply powering this converter must be capable of providing the maximum power drawn by your load. If the input supply is not capable of providing the power, the converter will fold back the output voltage as necessary. Example: If your load draws 1A at 9V (9W), and the input supply is only capable of providing 12V at 1/2A (6W), the maximum output voltage the converter will deliver is 6V (6W/1A).

Package includes:
  • 1X 8V to 24V Input to 9V 1.7A Mini DC-DC Step Down Converter
