Good morning, sorry, with a dps 800 gb-2A is there something different than this in the video? Thanks
Where can the larger IGBT (Bricks) be salvaged from? I understand they're generally in large inverters but every time I go to the scrapyard I only find the smaller variants and am looking for 400+A 600+V ones.
That is most likely to be found in very large x-ray HV generators, variable frequency drives or UPS systems. But we are talking in the 70-150 kW ranges. These units are usually in the full size 19" rack enclosures. Newer systems uses many smaller IGBTs and large bricks are getting more rare.
Wait the box said HTi but the device body said kmoon?
Nice spotted! I didn't even notice. I can't even google if kmoon and hti is the same or what is up and down there.
I have same tool, it’s good for diy and i think decent for electronics repair
ive got a bigger one :)
I always see your videos...all videos are very knowledgeable...sir kindly make a video on Fujifilm capsula x power supply failure.
Hi Sir how to generate service key is there any way to download software for GE UPS to generate service key????
Call GE.
@@KaizerPowerElectronicsDk Sir thank you for reply but i need other way to do this without inform GE
Potmeters Philips CRC17 series. They were a modular series. you could stack them in various configurations and make complex combinations including switches.
Awesome coil - I have build the 833A coil design and the arcs are very straight - but punchy on staccato - on C/W they are slightly more branched but not much - I guess - sometimes its a happy medium 👍👌👌👌👌👌🙏
Very straight sparks are normal around 400kHz+ resonant frequency, did you change it to a higher resonator?
@@KaizerPowerElectronicsDk I used slightly thicker wire and different value grid leak resistor - have fixed feedback coupling and maybe slightly wider diameter and longer secondary form- When I was first going for maximum spark length - I did get primary trying to arc to the secondary - so I used mylar insulation and tried moving to primary to secondary coupling hight - It sounds like a whip cracking😂👍
I have always noticed the similarity of whirlpool shadows to black holes
Yet another clue given to us to enable us to think about our world. There's lots of clues, everywhere and they tell us how the world is constructed (beautifully and perfectly).
Looks alike, but it's not. I mean .. what would be the analogy for the sunlight (that's been bent and outwards to a circle by the shape of the water funnel and that's why we see a black spot with a bright outer edge) in space time / black holes?
as the light passes through the curved geometry of the wirlpool funnel the refraction creates a region where no light touches, and all that light gets redirected to the edge of this circular shadow.
Can you use a voltage multiplier with capacitors and diodes to the the cap bank instead of MOT?
to charge the capacitor bank*
yes, you can use a wide variety of power supply methods. The charge current available will however determine the charge time.
Cool clip! The whirlpool looks exactly like how the bending of space/time is represented, for a black hole.
I think it's due to the different refractive index of air and water. As the whirlpool forms and the surface of the water in the center is pulled down the angle between the incoming light and surface of the water within the whirlpool changes. At a critical angle the light will reflect instead of passing through (forming the dark circle). It seems related to a phenomenon called "snell's window". It's also absolutely mesmerizing :) Thanks for sharing!
Snell's window is fascinating, got me further on to total internal reflection and unfortunately all examples of the law and concepts, works out from a flat surface. Anyone got a program to raytrace sun down through a funnel of water?
That's just made my brain itch!!!
😮 looks pretty cool!
The orbital mechanics and your floating debris seem analogous. The space/water surface is bent, and the object floats away from both buoyancy and momentum vector. The surface is also preferentially getting sucked in, giving the "gravity". Thus, you see opposing forces oscillating like an unstable orbit. For the shadow, I think we have multiple air/water interfaces at work. We normally see water on an approximate plane. I'd need to write this out but suspect the three big factors producing the round shadow are: Simple reflection pushing light out of the area (noting the water/light critical angle is constant and the vortex round and its curve continuous); internal reflection (noting the "over-sharpened"/glowing edge of the shadow may come from light passing through two sets of interfaces); and, by extension, a small amount of double refraction (helping enhance the perimeter light). This is an excellent problem for Walter Lewin's channel "
I know the funnel is not black hole'ish, as a black hole should look the same from all directions. Maybe the halo comes from light being reflected upwards from the bottom of the funnel and ends up being reflected by the upper curvature. I also like the extra small bow of light on the perimeter, clearly from the angle of the sun in this setting.
Hi
Aren’t 811A tubes rated at a maximum of about 1500 volts? How much over that are you going? I’m VERY impressed with that output from just two of those tubes!
Hi, I have (10x) 1600A , merlin gerin breakers interested in buying from me?
What is the lug between the ferrite coil and blue thing
On the right side of the blue-ringcore-blue, its the earth connection terminal to chassis. On the left side, which I assume you mean, in the white circle silkscreen. It's a lug used as a bridge, instead of the missing inductor, which is circle silk screen is for.
The SUVT/Galaxy 3500 was engineered in Kolding, Denmark back in 2006 - 2008. That is why the power boards are marked "Engineered in Denmark". The unit is no longer in production, but as always we promise to support with spare parts up to 10 years after official discontinuation. The SUVT/G3500 was replaced by the Galaxy VS which was also engineered in Kolding, Denmark.
Could i have Fujitsu DPS-800AB-1 A pinout diagram please?
It is in the description.
Thank you for this one
You are most welcome, thank you for following :)
This is awesome 😎👍
40 kVA bass audio amplifier :D
@@KaizerPowerElectronicsDk I guess they're using something like this on those hardstyle music festivals xD
My guess is that a scrapper got to the unit before you and removed the easily removable "precious" metals.
with a crane!
Some nice bits on there mate, definitely worth getting imo.i knew the big UPS are better but id still take these for sure 😎👍👍
I need to find something for the 47N MOSFETs, 60 just out of these boards!
@@KaizerPowerElectronicsDk its nice to have 60 of the same FET, I'm sure they will come in handy at some point 😃👍
Anything on gate drivers
The small individual boards I pointed out in the video is a gate drive transformer and passives. The main driver output stage, under the silver color heat sinks, is 20N60C3 MOSFETs, so quite a stiff driver for all those IGBTs/MOSFETs in parallel.
@KaizerPowerElectronicsDk thank you sir.
sexy looking boards!
It was a good choice with large yellow caps, does something for the view :)
Mosfets and OGBY devices are perfect though to repair your regular SMPS units, as they will work in most smaller units well, provided your drive circuit can drive the input capacitance. The rectifiers as well will be useful there.
All is saved! Don't worry, the boxes of IGBTs and MOSFETs is bulging :)
The juicy electronics 🤤
Would you write 6.66 kVA or 6.67 kVA?
Nice inductors for a reactive load for amplifier's if they're approximately 20 - 50 mH
Very hard to get off the boards in one piece, epoxy, heavy copper wire and soldered in with 4 or 6 points.
@@KaizerPowerElectronicsDk Yeah pitti , coating is the worth but I had success with super paint stripper still a not so nice job to say the least
At the junkyards near me, the employees don't let you take anything away 😭 I once tried to grab something in the electronics section and someone immediately shouted at me
here something like a junkyard dosen't exist😭
You have to buy this stuff from the scrapyards, it's not free, you need to speak with the guys and boss etc and come to an agreement
Public recycling stations are like this, all over Europe, due to environmental laws. The manufacturer actually owns the discarded electronics, once its delivered to a station. I get my stuff from privately owned metal recyclers and scrap yards, here you can buy stuff at their sale prices and if you are lucky, they consider all electronics as waste that cost them money to get rid of.
@@KaizerPowerElectronicsDk yes the government owned recycling centre is like that here too but the guys that work there take stuff home 🤣,
@@xntumrfo9ivrnwf oh you mean you tried to take stuff from government owned recycling centre? Yeah those places don't let you take stuff in general although there are some that will, my friend in Germany gets a steady supply of bits from the one near him, the rule in my local is you can ask other people for stuff as they are unloading but you can't take from the skips
Im interested in the MOSfets, IGBT's and large inductors! Any chance you want to part with them?
Same
Hit me with a message :) here kaizerpowerelectronics.dk/about/contact/
Please help me- I've byilt a dozen different sstcs featured in youtube videos (several iterations of each one) wirhout ever getting even one spark one time. I dont know what im doing wrong. This is so important to me and i have nowhere to turn for even advice.
Hi James, check out www.highvoltageforum.net
Would just removing the ground pin (without isolating the chassis) on the AC input work? THANKS MUCH!!!
This might trip RCD/GFCI from leakage current, when putting more in series.
Ima big fan of these big fans!
I got many fans and need more fans. More fans videos to come!
Be sure to check out the server fan video I made!
i got one of those sort of its a a12b men from a german manufacture uses a MPC8245 and uses Vxworks 5.4
Have a nice day You made an interesting video The same unit was given to me for repair, the capacitance of the capacitors was greatly reduced, but on the board, which is standing vertically, the diode failed, the marking on the board “D2” case type TO-252/DPAK, the name was lost. There is no way to take another block Do you have the same block or information about what kind of diode it is?
How to break KZread's compression algo in one short!
Oh wow that is bad! ❤ Full video is better quality :)
You can watch the entire teardown video here: kzread.info/dash/bejne/ZIiKu7iOZN3RY5c.html
How do you made it ionizing in the air without the direct sparks? is there a setting?
Noic! This is possibly the galvanically isolated version.
How you do this??? what was the frequency you use to made it float like that?
You need a dark room, a circular sharp edged object on one terminal and point on the other. I am unsure about driving frequency as this driver is feedback driven from the core itself, so it relies on the L + parasitic capacitance resonance in the flyback transformer itself.
@@KaizerPowerElectronicsDk hey brother do you have a email or fbook i want to see if you can see this picture and tell me what you think this guy is doing...
@@KaizerPowerElectronicsDk i got the flyback but seem like your not telling me the other part that i need?
Beautiful construction and PCB layout
Сколько преобразователю лет? Что это за старинный дизайн такой?
I doubted the 230/400V but is actually is. So what the hell runs on 400V single phase there or an odd combination of 230/400 like that? Since from neutral to each phase is a 120 phase shift, if it was 180 it would be 230/460V. Or do some house get fed like that to split the loads across two phases and save on wiring in a third and the loads are all 230V?
It just uses 2 out of our 3 phases. So there is still 120 degrees between them. All Danish houses are fed with 3x400VAC.
@@KaizerPowerElectronicsDk OK so what is the purpose of missing one phase if the houses are fed three phase? Are there any 400V devices or is this just to save on costs and run two 230V L-N phases instead of three.
@@inothome Good question. I think it is an adoption from standard products to Danish markets where subsidies from government to solar panel owners was limited to 6 kW installations. Balancing the entire distribution system was properly not considered to be an issue, unless installers get directions from power plants on which phases to install it to.
@@KaizerPowerElectronicsDk Ahh, ok. That can make some sense of it. Thanks!
Very cool, thanks for sharing!
The sharing. I like to do it.
Wow, beautiful looking inverter ❤️👍👍👍👍
