A friend of mine works for Teatronics, Inc. Teatronics makes multi-channel analog and digitally controlled dimmer "packs", from 4 to 24 channels. In the models that carry a 2.4 kW load they have LARGE inductors on the outputs of the TRIACS. These inductances are not measured in Henries but in Seconds (of rise time). For a typical 2.4kW (20A) channel, the inductor is spec'd to not be less than 500 uSeconds (micro). I hope you can figure out what inductance this translates to for your system. ****************************************************************** * John "Microwaves are for cooking" Flowers /_/ \/\/ * * johnf@scd.scd.com, hplabs!hpscdc!johnf / * * HP Santa Clara Division, Microwave Counters Manufacturing * ******************************************************************
