What is the default dimming mode for a Foundry Phase Adaptive Dimmer?
The Foundry Phase Adaptive Dimmer (UFD or UFD-277) defaults to Auto mode, which is reverse phase but switches to forward phase if the load is detected to be forward phase. This means in essence the default is reverse phase. The unit can be set to Forward or Auto modes.
