The 40A 3-phase Controller is currently under construction and not working yet. It is desighned to drive my 3 bigg coils (8", 10" and also the new 12" pipe)with 3 phase-current. It is build to run from 3x16A and 3x32A mains connectors.
	Here you see the Plexiglass-Frontpanel of the controller. This time it is build in a heavy flightcase because of stability and it´s weight (~90kg)
	The power section for the HV-Trafo outputs is done with 3 40A variacs. All cabling is done with 6mm² copperwire
	The variac-axes act together through a drivebelt so that every phase has the same voltage.
	Here you see the 3-phase Schaffner Linefilter that can take at least 37A for 10 minutes (more than enough for teslacoil use) You also see the two input contactors that automatically switch when one of the inputs (16A or 32A) is connected. The first power input that is connected to the controller has priority -> if both contactors are powered only the first one is switched through to the variacs. With the On/Off contactor on the front I can turn this contactors off (Also the Emergency-Off disables both contactors)
	Here you see the controller with closed cover, it´s water and dust proofed, so that I can not damage the panel while moving it. The case has 4 wheels, 2 of the are able to brake.
	Here is the fuse panel on the outside of the case, at the moment I took what I had at hand to close the hole for the coming 3x32A fuses on the left, the 3x16A fuses are still connected.
	Here you see what I´ve done so far in the inside of the caes, The whole case is hold together by very heavy metal-rails. On the front panel you see the small variac for the indirect light that I use for spark-photography. It can handle 1A continuous -> Thats a 250W light-bulb.
	OK, now to the functions of the controller: On the left is the mains power switch that enables 3-phase imput and switches it through contactors to the variacs. Below is the Sparkgap switch where I can choos from "Permanent On" and "Automatic On with the HV-Transformer". Below is the Emergency-Off button (not bought yet). There are 3 A-meters and 3 V-meters for the HV-transformer and 2 V-meters for light and sparkgap. With the 4/8A Sparkgap-Variac I can control voltage for ASRSG as well as Phase for SRSG jest by putting the switch below in the desired position. The Trafo Output is switched on with 2 buttons "On" and "Off" I will also build a remote on/off like the one from the 20A controller
