One other question, the diagrams have fans in them. I was going to add a heat sink, which obviously need a bit of air flow. Has anyone has any luck doing it without fans and just a heat sink? I was looking a power supplys/transformers, and they seem dear for a 5w unit (like $80), when a 100w unit is like $20. I'm looking at an analog voltmeter (to cut down on the fluctuations), so if I can get away without the fans, I'm sure I can save a fair bit on that power supply. Otherwise I'll need to work something out.Maybe an old lead acid backup battery to run the fans.

Cheers again!

Yeah i need to plan this out a bit. I'm thinking box, punchy's design - transformers/digital readouts. Then its just 2 sinple circuits, 1 with the SSR/pot/Voltmeter and another with the fan and a switch. If the IEC plugs have a fuse in them even better, protects the lot. Is the one you have the IEC plug with the switch on it?

Thanks for the feedback, I've spent so much time on the still and washes now I've just got this last element before its getting close to ready.

I'm looking at the data sheets and its got an F175 supply filter in the circuit, for what i assume is protection for the rest of the circuit? Or is that performed by the SCR fuse in this diagram? (I've attached the RS components data sheet)
...

I was wondering a) what it does and b) whether its needed.

Phase-angle power controllers generate Radio Frequency Interference (RFI) during each half-cycle of the mains waveform when the power is switched on. In sensitive applications this interference, or interaction with other equipment, must be suppressed to comply with the Electromagnetic Compatibility Regulations 1992 (SI 1992 No.2372). Appropriate suppression may be achieved by the addition of a series choke and capacitor network incorporated in a filter module. The F-type series filter modules have been manufactured to complement the UAL range of phase angle power controllers.

Only thing i was curious about. These phase angle controllers seem to control the neutral on the way out rather than the positive.... does that seem right? I would have thought its easier to control the positive, meaning the earth and neutral stay basically the same.

Cheers all, I'll start positing in the stillin areas once I've got this baby up and running.

Cheers

The cheap ebay (blue back light?) readout screens come to mind.

Your sparky will understand the diagram, mine did while I couldn't.
Are you going analog or digital display?

As everyone is aware, electricity is not to be taken lightly. You rarely get a second chance when it comes to an electric shock.

If you decide to take this project on, and are not an electrician, then you must get it checked by an electrician.
