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.

Wait the box said HTi but the device body said kmoon?

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????

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 👍👌👌👌👌👌🙏

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?

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!

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 "

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

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?

Thank you for this one

This is awesome 😎👍

My guess is that a scrapper got to the unit before you and removed the easily removable "precious" metals.

Some nice bits on there mate, definitely worth getting imo.i knew the big UPS are better but id still take these for sure 😎👍👍

Anything on gate drivers

sexy looking boards!

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.

The juicy electronics 🤤

Nice inductors for a reactive load for amplifier's if they're approximately 20 - 50 mH

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

Im interested in the MOSfets, IGBT's and large inductors! Any chance you want to part with them?

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.

Would just removing the ground pin (without isolating the chassis) on the AC input work? THANKS MUCH!!!

Ima big fan of these big fans!

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 CZcams's compression algo in one short!

You can watch the entire teardown video here: czcams.com/video/2TVYVU4zk34/video.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?

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?

Very cool, thanks for sharing!

Wow, beautiful looking inverter ❤️👍👍👍👍

Hi, to be honest, i was pleasantly surprised when i saw that familar shape on the thumbnail ^^ I've been with Fronius for almost 10 years now, so the IG Plus line of inverters was already cancelled and replaced by the SnapINverter series when i joined, but i had my fair share of work with the components in the electronic manufacturing department, as it was sold with up to 20 years of warranty. The lower section of the inverter, that is missing with yours containes the AC and DC connection area and the system control board, as well as the display. 60Vdc are way to low, i would need to look at the datasheet again, but start up voltage should be around 250Vdc. Each power class uses the same board + inductor combination, it's numbers are varying, depending on the phase number and AC output power. There was a revision of the power board, you either have the older PINCI 1, or the more recent, backward compatible PINCI 2 board. The newer one can vary the power factor, as some DNO require a Q/(U) or Q/(P) control. If you want to make the INV operational again, i can send you the article number of the bottom section, you need a specific control board, called the IG brain (yeah, the pcb designers had the TV show (Pinci and the Brain) in mind 😅, when naming the boards), that has been programmed for a 2 power stage / 6kw output power inverter and the specific region. Ps: the conformal coating was dropped with the succeeding generation of inverters, as by then the housing was IP66 protected, so nothing stopping you there from salvaging some components!
