I'm looking for a current-limiting SSR for switching single-phase AC. Another engineer told me that he used one a couple years back but cannot remember the manufacturer. Apparently the series has parts ranging from 5A to 25A continuous and performs active current-limiting for inrush (and post-inrush). It won't draw more than the rated current and will chop the waveform as needed to perform the active limiting.
Has anyone heard of such a unit?
Thanks,
Dan
Actually, by definition a SSR would not be capable of current limiting since it would just be an On-Off device. However, the type of device you are referring to is called a Phase Angle Power Controller, differing from a SSR in that it can continuously limit the current output by phasing back the SCR firing angle. Try Phasetronics in Florida.
