Re: WA6-30N High Voltage Enable

Are you you enabling (shorting) the safety interlock before plugging in the AC power?

Section 3-1 in the manual shows the steps you need to follow.
Section 4-4 states that if the interlock is opened the output is cut off until the AC power is removed and turned on again.

Re: Couple of questions

Educating people on safety is always a good idea since it helps people develop lifelong respect for such dangers - as all would agree, an ounce of prevention is worth a pound of cure. I certainly have seen many an educated scientist ...

... between patient and detector. https://radiopaedia.org/articles/grids Dennis, please keep raising flags when someone appears to be cavalier about safety. Never my intent, but writers might not recognize a possible misinterpretation. When I once showed wire-balling arcs and a xenon short-arc lamp ...

Re: Couple of questions

... over 20 kV.) One must calculate the thickness using the max voltage your system will have. Agree with Ian that good ground system is critical for safety as well as using proper high voltage cable (i.e. correct voltage rating)! Valid grounding is absolutely necessary so one does not 'float' their ...

Couple of questions

Hi I got my vacuum chamber that going to use and pump Parents wanting plenty of safety features So wondering where could source some lead sheeting from to make a box for chamber to go in for neutron absorption And what would a faraday cage be good to make out of ...

Re: Ballast resistor construction

... a brute force x-ray transformer supply, but without rapid fine tuning, it’s hard to keep it stable. I’m keeping the resistors inside the tube for safety and hoping convection will keep the ozone cleared, but I may need to add a blower at the bottom. Thanks for the feedback on this.

Re: Ballast resistor construction

... configured things so the HV was passing through the .9 M resistor to the arcing point so it happened to have some limiting too. Just a note on safety, my load resistor and a HV divider for measuring voltage were well away from my operating point of the supply and were on a ceramic tile floor. ...

Re: Does this look sufficient for a proof of concept fusor?

... you will need some type of gasket to form a 'soft' seal to the edge of your bell jar. That is critical for both a proper seal for vacuum and for safety. Cutting a ring of rubber like material to match the edge of your bell jar is rather easy. A simple base would be a large enough piece of any ...

... electronics in that tank either. Just 220 ac in and a gang o' volts coming out. Just a transformer and a bridge rectumfire along with a bunch of safety nerd stuff to multi-interlock the system in the off mode until the cows come home. This schematic is typical and much like my own XRF system ...
