hi technogeek,
Sorry to keep chewing on your leg bone
BUT the following quote is not technically accurate.
technogeek said:
An isolation transformer would limit the current through said unlucky person, but considering 100ma(?) can kill a person, and this circuit will use about 60ma to create 6w out (probably more due to low power factor), the circuit would be deadly even with it.
With an isolation transfomer the unlucky 'victim' would have to get across BOTH the secondary wires of the transformer,
the isolation transformer would NOT limit the current in that case.
It would however prevent a electrical shock from one transformer secondary wire to Earth.
That is, the isolation transformer is primarily for Line/Phase to Earth protection.
I did ask in an earlier post 'what are you going to reference the PWM pulses from the PIC to?'
Unless you used a opto isolator, the PIC 0V line would be connected to mains Neutral,
or in the event of an incorrectly wired power outlet Line/Phase.
I realise that the project would be totally enclosed, but you didnt say that earlier on.
You can appreciate that we do not know your level of expertise, so we have to err on the side of safety first and not to dumb it down.
Regards
Eric
