    Default Control more than one output from single channel

    Newbie, so bear with me

    As I understand a four channel dimmer allows the control of 4 separate outputs from one or more combination of inputs.

    Say I have two wall lights which I would treat as a pair and would never do something to one without doing to the other one (dimming or on/off), can I use single channel to control both, or, because of voltage/power considerations, I should wire into separate channels and leave at that.

    Reason I ask is that I am trying to get a ballpark cost for all this stuff for new house, and there are a number of similar situations to that above.

    Thanks
    Tony

    Default Re: Control more than one output from single channel

    A single channel may be used to control a group of lights providing their combined current consumption don't exceed the channel maximum at any time, including at start-up. As you have already pointed out, combining the lights would make them behave as one with no individual control.

    The C-Bus L5504D2A 4-channel dimmer can handle a maximum of 2A per channel and the L5508D1A 8-channel dimmer has a maximum of 1A per channel.

    Default

    current = power / voltage
    i.e. 240W is 1 amp 480W is 2 amps etc
