Group: Tinkerer Hero Member Posts: 3948 tExB=qr	This thread is for discussion of power supplies for the AVEC Device... On page 20 of The Aether Vortex Energy Converter: AVEC, Revision 1.0, it is stated: Quote If you use a 1200V/1300V or 1400V cap there are a handful of mosfets that could do the switching rated at 1500V. The current max should be well below 50ma. Protection diodes should be used. The snubber is a must; check out the tech sheet pdf on snubber calcs sent previously. This small current requirement is easily met with small flyback converters and neon power supplies.

Group: Elite Hero Member Posts: 3537 It's turtles all the way down	This is what I use for most of my testing, constant voltage, constant current or constant power. One can be had on ebay for $100 (typically $400 surplus but original cost $$$$). They were made for electrophoresis work and are lab grade. Be careful...up to 2500 volts. Edit: Some of these electrophoresis units put out pulsating DC and may not have internal filter caps. Easily modified though. ------------------------ Power Supplies Hoeffer.jpg (308.89 kB, 1223x705 - viewed 1437 times.) « Last Edit: 2010-09-27, 12:15:38 by ION » --------------------------- "Secrecy, secret societies and secret groups have always been repugnant to a free and open society"......John F Kennedy

Group: Administrator Hero Member Posts: 3217 It's not as complicated as it may seem...	There are a couple of these PS2500's on ebay. Cheapest is $200. Other about $250. Add at least $50 for shipping in the US. Probably $150 to Canada. Are these not PWM units? Would be nice to have a home-brew design all could easily build. I'll add it to my to-do list of test equipment designs $:-\$ .99 --------------------------- "Some scientists claim that hydrogen, because it is so plentiful, is the basic building block of the universe.

Group: Elite Hero Member Posts: 3537 It's turtles all the way down	AS GK and Grumpy will soon see, these electrophoresis supplies are not toys, they are very robust and heavy units capable of delivering their max power rating continuously. They take a little getting used to. The Hoefer units remember their last power setting and continue from that setting in the event of a brownout. The EC600 will not start if it senses an EMF present at it's output so I use an isolating diode if my DUT has a battery ot capacitor which can backfeed. The Hoefer unit goes to 2500 V, EC600 goes to 4000 V. Nice to be able to limit voltage, current or power. The wattmeter is also a very nice feature to have. You simply cannot beat the bang for the buck these surplus units deliver. I am grateful to have these devices on my bench. --------------------------- "Secrecy, secret societies and secret groups have always been repugnant to a free and open society"......John F Kennedy

Group: Elite Experimentalist Hero Member Posts: 1593 Frequency equals matter...	I felt an upgrade from the hand cranked supplies I built would be better. Looks like I one-up-ed G on the V! LOL. And we shall see. Stated in the AVEC thread: for now I only want a better HV control. --------------------------- http://purco.qc.ca/ftp/

Hero Member Posts: 520	And I'm still rubbing sticks together. Wow that 4000v range looks very interesting. I can only imagine pulsing that high voltage at high frequency, what the effects would be. Its also a good tool for testing step down techniques. Hmmmmm. --------------------------- http://etherimpress.com

Group: Elite Hero Member Posts: 3537 It's turtles all the way down	Hi Poynt Quote Perhaps a toned-down variation of this might be an option. Another page with some ideas. .99 That first link looks like a good one for brute force work. Can be built from scavenged parts. Regulation might be a problem with the voltage multiplier, but for Hi-Z constant loads probably ok. The second link are flea power output good for light electrostatic work. I use corona wire supplies from old laser printers and copy machines......but for those who like to roll their own..... --------------------------- "Secrecy, secret societies and secret groups have always been repugnant to a free and open society"......John F Kennedy

Group: Administrator Hero Member Posts: 3217 It's not as complicated as it may seem...	Hi ION, thanks. I found those links in a 2 minute search. Not sure if they were of any use or not. Perhaps it's best to just spend the $400 or so on an EC600. We'll see. .99 --------------------------- "Some scientists claim that hydrogen, because it is so plentiful, is the basic building block of the universe. I dispute that.

Group: Tinkerer Hero Member Posts: 3948 tExB=qr	I went for the Hoefer because I wanted more current and the ability to easily adjust everything. I was getting good results with a 4000v converter at about 20ma. Turn the current down and use the constant voltage setting and should do fine.

Group: Administrator Hero Member Posts: 3960	What a bargain for such a power supply, these i bet will go up in value as more OU people catch on. Wish i could grab one myself, but the shipping and import tax to the UK puts it outside my current pocket money level

Group: Elite Experimentalist Hero Member Posts: 1593 Frequency equals matter...	I got mine yesterday also! 160USD. It is cleaned and setup on the bench. I turned it on and no smoke. Have to get HV wire for leads today. What a find! I like the adjustments and meters. --------------------------- http://purco.qc.ca/ftp/

Group: Elite Experimentalist Hero Member Posts: 1593 Frequency equals matter...	Very valuable. I also saw a self oscillating flyback to Villard bank powered off a 12v battery. Very cheap way to get HVDC. With that said this would be a good introspect into the small component count in the TPU to produce an HV bias. Starting to more and more like a stungun.

Group: Elite Experimentalist Hero Member Posts: 1593 Frequency equals matter...	Here is the current shout progress about my ec600" (18:20:11) tao: (19:42:47) poynt99: news:O How about I spent a couple hundred bucks on yet another boat anchor (19:43:49) poynt99: Love that old HQ test equipment (19:44:42) poynt99: I hope this one works out of the box....they seldom do in my experience anyway (19:45:24) poynt99: usually f@#$%ked up by some jackass that tried to repair the thing.... (19:46:23) poynt99: never done right, and they always seem abused. Well I guess that's how lab test gear goes most of the time (20:46:31) giantkiller: your ec600 is trash? (20:57:57) poynt99: Not sure GK. Ihaven't received it yet I just referring to my previous experience buying all the HP etc. equipment I have (20:59:59) poynt99: even the scope which I paid $2k for apparently has a fault in it. I'm hoping I can repair it (21:00:42) giantkiller: I put a meter on mine in the 50v range . volts adsjust did nothing. (21:00:50) poynt99: there is often a reason equipment ends up on ebay...it's a risk, but as long as you are handy and can get schematics, you might be ok (21:01:54) poynt99: hang one sec while I pull up a picture of one (21:03:51) poynt99: are you sure? I think the min voltage range is 500V (21:06:19) poynt99: (21:07:19) poynt99: (21:08:17) poynt99: and pressing the "start" button doesn't give results? (21:11:45) poynt99: hmm, seems E-C Apparatus is out of business (21:11:50) poynt99: (21:21:04) poynt99: I think Thermo Scientific bought the rights to E-C Apparatus (21:21:27) poynt99: I have contacted them via email asking if a manual might be available for purchase. (21:21:45) wattsup: ebay is the lake and we're all fishin. (21:22:00) poynt99: you may contact them also: 1-800-874-3723 (21:22:12) poynt99: yep (21:22:31) giantkiller: i am hooking up the 2meg res and a uwave diode to see if the external meter will register (21:23:13) poynt99: good luck, hope it works (21:23:32) poynt99: Do you get any output at all? (21:23:44) poynt99: on any range or any setting? (21:24:05) poynt99: I would not be surprised if the output is fused (21:24:12) poynt99: have you opened the unit up? (21:24:39) giantkiller: i am at 100vdc! looks like I have a unit so far. I need to make the resistor div to the meter for hv (21:24:50) giantkiller: yes I have opened it up. (21:25:08) wattsup: drum roll please....... (21:25:32) giantkiller: I still have to test for the other switch settings. (21:25:50) poynt99: ION mentioned that it wants to see a min load I think? (21:25:51) giantkiller: there relays in it. And when they click you jump! (21:26:30) giantkiller: you turn it on. (21:26:40) giantkiller: then press the set button. (21:26:59) giantkiller: press the norm button (21:27:11) giantkiller: then press the dc on button and your good to go. (21:27:31) giantkiller: after the set button you adjust (21:27:43) giantkiller: then the norm button (21:30:09) poynt99: kinda makes sense (21:30:31) giantkiller: some shout arent getting thru (21:30:47) giantkiller: up 400vdc at the 1k button (21:31:12) wattsup: and it is supposed to go up to 4000v? (21:31:12) poynt99: yeah, it's a known problem, sorry :? (21:31:39) giantkiller: i need bigger resistor for the divider up to that. (21:32:18) poynt99: what makes sense to me is to use "Normalize meters" to zero them, first. Then use "set reading" to adjust the voltage, then press the "start" button (21:32:31) giantkiller: so all 3 knob are needed to set an output. (21:32:40) giantkiller: .99 yeah but other way (21:33:00) giantkiller: no you right (21:33:47) giantkiller: so far this just shweet! (21:34:09) poynt99: great! (21:35:52) giantkiller: just took it upto 1kvdc! the unit holds it settings! the ext meter flipped out. max 1kv (21:37:13) poynt99: (21:37:41) giantkiller: the 1kv test was on the 2kv, 20 watts, 5ma buttons (21:38:04) giantkiller: so I go to fistells tomorrow for the big divider (21:38:28) giantkiller: suhweet! (21:39:04) giantkiller: the unit does take a moment to normalize and a bit to bleed down when off. (21:40:01) giantkiller: i want to use the pots off a flyback to divid. any comments? (21:40:48) giantkiller: i also have the huge diode from my exploding tv replica (21:41:56) giantkiller: also the ec600 'at setting' light come on at the correct time. (21:42:05) giantkiller: liths (21:42:12) giantkiller: lights, finally (22:03:47) giantkiller: i will call 1-800-874-3723 (22:05:41) giantkiller: oh yeah. I been upto 1k@5ma --------------------------- http://purco.qc.ca/ftp/

Group: Administrator Hero Member Posts: 3217 It's not as complicated as it may seem...	Received my EC600 today. Unfortunately, the seller did a very poor job of packing the unit and it has suffered significant chassis damage from a drop or two. I have not powered the unit up, and I'm not really inspired to now. I have emailed the ebay seller to see what they want to do about this. We all make mistakes from time to time, but this thing weighs quite a bit, and how to pack it properly should have been a no-brainer. $:-\$ I hate when this happens! .99 --------------------------- "Some scientists claim that hydrogen, because it is so plentiful, is the basic building block of the universe.
