    Trailing edge version of QLD (4 channel dimmer) released

    Although it was first in line to be revised it somehow ended up near the end of the list..

    Anyhow just to say that the QLD-003 has now taken the place of the former QLD-001. Although it looks similar it is very different under the hood. This version implements trailing edge dimming so generally speaking better suits dimmable LED lamps. Separate power mapping tables exist for each channel so possible to adjust these to suit different lamp characteristics on a per channel basis. Since the module uses a full mains connection there is no minimum load per channel and also since slew rate is now controlled in a different way the module can also switch non dimmable loads on selected channels - so long as it is set not to ramp these in Cortex. However this is not really a good long term or cost effective way to control non dimmable loads - use a QTI or one of the relay modules instead.

    4 channel trailing edge dimmer, 250W per channel, 8 general purpose digital inputs, 6M DIN Rail enclosure format
