Voltage Divider

Good evening, folks!
Well I am a flash fan and I always want something special. I need a different Voltage to test my devices and it was always a problem with this. Today I say myself - enough with improvising. I took pencil and made a circuit ... cascade Voltage multiplier...

I assemble this on chipoard and put nearby A4 paper ... to see dimensions...

Data:
Source 220V AC
Cascade circuit double,triple (can on "N" ) Voltage ) ..it is used commonly in Bio-ionizators.
I achieve about 522V DC on both ends with two diodes and 1 capacitor (block).

It is hard to find a 10W potentiometer of 20MOhm so I select  simple 20 pcs resistors 5W 2 MOhm.
Switch, fuse, two 1000V diodes1A, capacitor 600V 2mF...

Test was made on chipboard  --- but I have to made a proper box... of course from 4mm Plexiglas (Lexan). 522 Volts are not a joke... Color is also a matter of taste..

Here you can see a holes for plugs... 10 blacks and 10 red... you can choose a different color.

Ready to switch on... me in background.

For testing my Braun vintage flash I need  510V E497 battery .... not any more.

Well, on the step nr.10...   272V... and so on....on 20 steps.

So, after a several hours, I finished this divider. Now I have what I want ... relatively safe.Thin flat box on table. Everything under eye.

Note:
If you made this - its on your  risk.



Sincerely
Kresimir
