Title: AC Negative Ion Generator Post by: kang2008 on December 24, 2007, 08:15:30 08:15 hello?
i need AC Negative Ion Generator schematic? input ac:100~240v output : -3000~-7000v thank you. Title: Re: AC Negative Ion Generator Post by: mississippi1 on December 24, 2007, 11:41:07 11:41 Here a link to a schema.
Succes with it, but be carrefull because the circuit is directly connected to mains http://www.uploadarchief.net/files/download/ionisator.gif Title: Re: AC Negative Ion Generator Post by: kang2008 on December 24, 2007, 12:59:07 12:59 http://lakewoodconferences.com/catalog/93/509/page2/27279/ac_negative_ion_generator.html

If you want to built one, use the schematic given by mississippi1 and built it according to the photoes shown in the link of kolin. The last photoes indicate some good ideas that avoid PCB and make a small size of ioniser. Some advices: Avoid sharp edges in any areas of the constraction, soldering point must be as round as possible. At high voltages sharp edges emmit ions, thus you have losses. Never try to measure the voltage with a multimeter, it will be destroyed. Do not touch any part of the circuit when is connected to main power. The voltage is so high that you can get a shock even if you use special insulated tools. The insulation of most tools is rated at 1000V, not 6000-10000V that a circuit like this produces. (I got a shock in the past from such a circuit when I was holding the output wire (insulated PVC wire) through a plier with 1000V insulation handle. The spark passes through the wires PVC and then the plier's insulation) If you want to make it small, use the smallest size of capacitors you can find at 630V. Any value from 33nf to 100nf will do the job. The 100nf produces slitly higher output. Title: Re: AC Negative Ion Generator Post by: rinderpest on January 03, 2008, 11:29:50 23:29 Main hint, in my opinion, is to have at least a 2M ohm resistor in series with the output. it wont effect the output but will massivly reduce the current if you happen to touch/short the output.
You can check how much crap you are pulling out of the air by putting a sheet of white paper under the ioniser; after a few days there will be a dusty splodge around it. |
