    in reply to: 200150 does not work #19713

    Hello John Tumminaro,
    #200150 is a boost converter. It can be only used to step up voltage.
    Therefore it is impossible to step down 20V to 12V.
    For more details about this item, please kindly refer to the product description.

    Hello Tomt,
    Thanks for your reply.
    We find out this item:
    090483
    Would you please tell us how large the input current is?
    We have asked out technicians to do some similar test according to your description.
    But it is normal even if the output is set as 5V 8A.
    We wonder if the input power is not enough or is there something that we have overlooked. Please kindly tell us the input current and more other details.
    Best regards.

    in reply to: Additional external shunt to allow greater Current testing? #19647

    Hello Bernard,
    Thanks for your business.
    It’s regretted this item is 20A specification. Even if you add a shunt, it is impossible to measure current over 20A. The meter will be damaged due to overcurrent. Hope you can understand.
    Best regards.
