Hi Roli!
>you cant compare general power supply with an ECT device........
I know. I was just thinking that 450 Volts sounded high.
>And also you don't get a constant current with ECT. they use pulses......
That's true.
Apparantly, the old machines used a 'sine wave'. I'm not sure what it involved.
>me too :-/ wasn't very pleasant. strangely the fuse didn't work. It was me, who was falling from a chair and thereby forced disconnection ... ouch!
When I was little, I accidently stuck my fingers in a light socket........and there wasn't a bulb in.
The Thymatron ECT machine.........
STIMULUS OUTPUT
Current: 0.9 amp constant, limited to 450 volts, isolated from line current.
Frequency: 10 to 70 Hz in 10 Hz increments (to 140 Hz with “LOW 0.25” program)
Pulsewidth: 0.25 to 1.5 ms in 0.25 ms increments
Duration: 0.14 to 7.99 sec in increments of equal charge.
Maximum output: Standard maximum output across 220 ohms impedance, 504 mC, 99.4 joules. Output with double-dose option (where available) across 220 ohms impedance: 1008 mC, 198.8 joules.
Since you're an expert in electronics, can you explain this????
Thanks Roli :-)
