    Hello
    Thank your for your reply.
    It doesn’t need specific input supply.
    The input voltage for this item is DC 6-55V.
    Just make sure the input must be DC-DC, unable to use AC 220V to directly supply electricity.
    For more questions, please feel free to contact us.
    Best regards.
