    in reply to: Maximum power rating for Digital Thermometer? #29710

    Hello Ryan，
    It doesn’t have maximum current rating. Just make sure the power supply can offer more than 50mA current and 4-28V voltage.
    Best regards.

    in reply to: YB4835VA 50A DC volt/amp meter panel – shunt required? #29709

    Hello Kris,
    We wonder if you mistake the item. YB4835VA is AC meter. It has a current transformer instead of shunt.
    Would you please send a product link for confirmation?
    Best regards.

    in reply to: 5.25" 6 ohm dual magnet woofer 40W #29695

    Hello john,
    The larger the ohm is, the smaller the output power is..
    We are not sure if your amp can work with 4ohm speaker. It may work with 8 ohm, but the output power is small.
    Best regards.

    in reply to: DC Three phase Hall Brushless motor drive board #29687

    Hello Dave,
    Thanks for your wiring in.
    The speed of forward or backward is the same in theory. But the actual speed will be affected by other things, for example, the resistance of backward and forward is different.
    Best regards.
