Build a Variable High Voltage Power Supply
I need to obtain High Voltage Power Supplier. I need Output voltage: 0 to 30 kV. Current: 0.5 mA to 1.5 mA. Below you had some properties that I need.Could you help me to develop this home made?TKBest regardsDaniel
Sorry, I thought I'd answered you. Since flux basically turns to acid when heated, and the acid is what de-oxidizes the metal, I figured I'd just go with a cheap, weak acid that was readily available. There may be a lot of these around, but I chose the one acid that is safe, readily available and found in a lot of foods, probably one or two that you've had this week -- phosphoric acid. It is found in many foods because it slows the growth of molds and bacteria, so not only does it add the zing to soda pop (not citric acid, as you might have thought), but it keeps the sugary treat from becoming a bacterial soup. Got to maintain those profits!You can get it online, but it is only $15 per gal at Home Depot under the label, KleanStrip Prep & Etch, for cleaning and etching cement floors, etc. It needs to be diluted with alcohol, of course, which means it is even cheaper than $15 per gallon. Try it on a circuit board to see if it is diluted enough. If it doesn't eat away at the coating on most circuit boards, it should be fine, but you can always clean away the acid after you're done soldering, just as some like to do with flux.I've mixed my own flux with pine resin, and that stuff is super sticky and not fun to use. It really has to be diluted. But why bother if phosphoric acid does the job without the complications? I've also filled cheap markers to use as flux pens. Dip your wick in it and it becomes super wick! It's wick'ed stuff.
Dear Sir,I require such a power supply for my research work. Can you sell me such power supply of very low current?Purnenu Laskar
thanks a lot for your information
do you ever made voltage multiplier, do you have id line? my id : hikmatsbor my email email@example.com please answer
if i want to make voltage multiplier 20kv with input 220V 50hz, what the best components to mak it?
Very nice article.
