Hi appologies if this is in the wrong thread. I am building a simple furnace for melting aluminium. I intend to use a 2500w kanthal coil with a PID controller, thermo couple and solid state relay. Ive calculated the coil will pull about 10-11 amps. I want to run it off a 240v 13a supply. As i may need to shorten the coil to get it in my furnace it will probably push over 13amps. So can i fit a voltage regulator between the coil and the relay to drop the voltage if necessary. Will this work?
