Power Regulator For Electric Element

[Yorg]

do a search on AHB for a sutronics burst fire controller.

It was I and many others use;

At the bottom, the Variable Voltage Output SSR (TCSSRR2540 0hms 70 - 240VAC $62.00) works for me, although for a slightly different purpose. This unit mounted on an appropriate heatsink, will handle up to 40amp currents. For those in melbourne, their store is two doors down from grain and grape, and they were very helpful when i was sussing it out.

Both of these look promising. Help me out here though - am I right:
The sutronics burst fire controller does not generate significant rf noise.
The SSR does.
The sutronics is more efficient when not operating flat chat.

??

Also, I think I might want to control 3600W, so 2 things:
What about this - http://www.sutronics.com/acatalog/detail_bfm240_25hs.html
And what do you think that 100K Ohm pot spec is supposed to be?

Just a bog standard linear pot, eg http://jaycar.com.au/productView.asp?ID=RP3518

Well, seeing you asked, there is a reason people go the RIMS/HERMS route. I would try a test run with the immersible element in a sugar solution of gravity approx 90. Scorch potential could depend whether we are talking intermittent high power or constant low power. Secondly, any thermostatically controlled, automated system probably needs a stirrer or some sort of recirculation.

Thanks for the suggestion, I haven't looked into the HERMS option and after reading about its operation, it does seem to eliminate scorch potential. Curious to know about peoples experience with it.
