Frequently asked questions
How do I check the barrel jack polarity before connecting?
Check the polarity marking on the adapter label and the input marking on your device before connecting. Reversed polarity can damage the device, so confirm the centre pin is positive or negative as the device requires.
Can I power a device that needs less than 24 V from it?
No, this is a fixed 24 V output. For a lower voltage, use a DC-DC step-down converter between the adapter and your device.
