Ss Brewtech econtroller wiring?

[handbrewing]

Does anyone have a diagram of how the Brewtech econtrollers are wired and what components are used? Any photos of the inside?

Their website says our eControllers include a fully proportional PID output, which doesn't rely on SSR's or high speed switching to modulate heat.

Which Omron E5CC model do they use that makes it fully proportional?

Can't offer any answers, but I'd like to know what magic they use to modulate heat without any high speed switching. I only know two ways to do this:

1. A linear power supply, which would be a terrible way to go, as to run at less than 100% power, the power that isn't going to the element gets dissipated in the power supply. So, the power supply becomes a ~5000W heater by itself.
2. A variable transformer or autotransformer, which would require a servo motor to actuate.

Anyone know what they actually do?

Edit: A look at their website reveals that they use SSVRs which are solid state switches that use TRIACs for switching, just like SSRs, but typically switch faster than the PWM (pulse width modulated) output of an SSR. They also don't do 0 voltage turn on, so generate more electrical noise than typical SSRs.

Brew on

The E5CC has different models so not sure if the specific one used in the Brewtech has anything to do with it.
