What is the maximum watts at 120volts it can support for hours. Plan to use to control swamp cooler fan speed.

120 volts * 8 amperes maximum continuous current equals 960 watts. The TRIAC can run at a peak load of 16 amperes , 1,920 watts, but this cannot be sustained for long. If you need higher wattage you’ll either have to run a higher voltage or run the two modules in parallel.
