Very nice demonstration of using an inductor in line with DC current from the diode. Inductor are short-circuit in DC current. In AC, they let much less current pass through. And that high current quickly got your inductor ballast.😂 Great informational video
Happens a lot with halide lamps too. Discharge lamps need to be individually fused - a 16A fuse for a whole lighting circuit isn't adequate. Halide lamps also tend to rectify at startup for a fraction of a second, so you get some nice grunting noises from the ballast, and a big current draw until the arc stabilises.
hii, i don't understand as well. a copper ballast is basically just a transformer inside.. with 2 separate coil.. why when he shorted the output coil wire, but the ampere draw was 0.4amp.. but when he put a half wave diode in the output coil wire, it heated up substantially ? why ? can you explain or any youtube explain that ? thanks andrew
The way a transformer works is via an AC wave form. It expands and contracts by the input AC frequency. With a ballast there's just one coil in an iron core. The amount of turns in the iron core makes a magnetic flux which limits the output current. This is a 240VAC 58W ballast. The lower the voltage the less current you'll get out of it but if you exceed the input voltage the ballast will get extremely hot and possibly burn out. But this all depends on how much you over volt the ballast. In England its 50hz and in America it 60hz, but the frequency doesn't matter when it's around that ball park but the high frequency transformers which are in the khz are a lot small for there size due to the magnetic flux. What I've done here is put a diode in line with the ballast which cansels out the magnetic field. Putting a diode in shorts the ballast out and doesn't create a magnetic field so it can't limit it self. Current is only flowing in one direction so it over heats it self and burns out. What I've done is short a bit of wire out. It's very simple if you know how it works but it's hard to explain 🤔
With AC you have a magnetic field which expands and collapses, with DC you don't have that. Transformers work by using the magnetic field which couple to the other coil and the different ratios depends on what the output voltage will be. Ballast don't have a secondary coil but the magnetic field limits the output current. With DC there's no magnetic field so it doesn't limit the current. It's just a piece of wire and because it's a small piece of wire in the ballast it gets very hot, so hot that the cable melts.
I know I said half wave but it doesn't matter. A full bridge rectifier with a large cap so it's proper full DC with no ripple will do exactly the same. When I used just one diode you can see and hear the magnetic field expanding and contracting. If I did a full wave with a cap there wouldn't be any ripple or noise as it's just a short circuit.
hello! call me an idiot if you wish, but how to you connect/disconnect the wires from that type of ballast? i have a light fitting with the very same ballast and the wires just appear to be pushed in? there does not appear to be a screw driver required etc? i gave the wires a reasonable tug by hand expecting to pull them straight out but no luck... What's the trick, i'm usually pretty good at figuring this stuff out? Cheers!
Probably not anymore with these Eco- friendly low mercury lamps. They are shit and go mercury starved at less than half of their rated lifetime! Seeing a very dim pink tube seems to be very common these days!
now maybe explain the difference between AC impedance and DC resistance, why it works on alternating current (50/60 cycle) and catches fire on direct current.
Well it's rated for 240VAC @ 50 Hz. Keep the same frequency and you can go from 0-240VAC and you won't burn anything out. All a ballast does is limit the output current. It's just one coil and the magnetic field expanding and collapsing is what limits the output current. Obviously the lower the voltage the less current you'll get out. You can over volt theses for short amount of time, but that once again all depends on the input voltage.
@@TheManLab7 Thanks for replying man. So a ballast is basically a large Inductor. It seemed like a transformer, so I thought would it step down the supplied voltage from the grid. Since it only has a single coil, it wont work as a transformer. Let me figure if this can be put to some use for any sort of project of mine. If you come across any idea, do let me know.
Thanks and yes, it's a beaut 😊 They definitely don't make them like that anyone as it's an old school which is built like a brick sh!t house! It's rated at 20A but I've had it WELL over that n it's never complained once.
No, this ballast brand is fine. He is showing what happens when you run it off of a DC current supply, instead of an AC current supply. The ballast (basically an inductor, also called a "choke" sometimes) doesn't limit the current on DC.
He still does love making videos. But he just can't be arsed with the hours of editing and rendering that goes with it. If he got someone else to do it, then he'd be putting videos up just like before.
hii, i don't understand as well. a copper ballast is basically just a transformer inside.. with 2 separate coil.. why when he shorted the output coil wire, but the ampere draw was 0.4amp.. but when he put a half wave diode in the output coil wire, it heated up substantially ? why ? can you explain or any youtube explain that ? thanks andrew
Haha...You popped it. :-D Just wondering: If you put one of these on DC, does it then act like an electromagnet? :-D Also, when doing this poppage, did you have another ballast in-line with your variac to protect it when the half-wave driven one went *POP* ? Interesting vid though. :-) Thanks for showing, -BoomBoxDeluxe.
I can't remember but I don't think there was one protecting it. It was just straight on the output of the Variac as it'd just blow it clear due to the amount of current going through it all. If the ballast didn't burn out then the tiny cables would end up being fuses, lol. This is just on one diode btw. I'm not sure what would happen if it was on a FULL BRIDGE RECTIFIER!!! with a smoothing cap.
I do talk and message him a lot and he's filmed some videos, but he's just CBA with all the editing side of things. It takes hours making even a small vid n he's just had enough of it tbh. I recon if he had someone to do it for him, he'd be putting loads of videos back up no doubt
+TheManLab7 do you not think ull have more fun overloading them crap HF electronic ballasts... they can not be switched more than 8 times a day or they will fry themselves they are basically a circuit board encased in plastic. and Vytautas Poška its only a tridonic ballast it would be a waste if it was thorn emi or something.
+joseph h yeah true, actually I have seen tridonic ballasts burning out quiet often, It would be more of a waste if it would be like vossloh schwabe or philips or GE. . .

nice video, inversely you could connect a cap to a dc source and it would just charge but if you connect it to ac you get "current flow" and heat
Great vid, hope you make a great recovery, and amazing how much money was raised for you too!!

Way to miss the initial flare-up camera man.
+Eric Hondel i was just about to post and insult the camera man too!
@@ChaosHusky it was my ex
Fascinating.
I love these experiments.
what if you put another diode in the other direction, but only use one diode to provide half wave dc for a load?
Always wondered what these things do when overloaded
Safety glasses sitting right there on the bench!
now maybe explain the difference between AC impedance and DC resistance, why it works on alternating current (50/60 cycle) and catches fire on direct current.
+firstname lastname because on AC the impedance limits the current going thru the ballast, on DC you only have the actual coil's resistance
So what can you use old fluorescent ballasts for? I just pulled a load out while replacing with led. Would be nice to use them for something
They can only be used for limiting the current n that's it
I have that same exact ballast at home. Is there any DIY project i can do with this ballast?
Well it's rated for 240VAC @ 50 Hz. Keep the same frequency and you can go from 0-240VAC and you won't burn anything out.

vytautas poška there is a ballast branded maspion from indonesia. it is 100v-125v ac but you find it in indonesia quite hard
Running it through a diode is virtually just shorting it.
I've seen this happen when a fluorescent lamp starts rectifying when it reaches end of life.
nice variac!!
Thanks and yes, it's a beaut 😊
They definitely don't make them like that anyone as it's an old school which is built like a brick sh!t house! It's rated at 20A but I've had it WELL over that n it's never complained once.

Yea sorry about not capturing it when I went up. Went to look at the clamp meter to see what it was pulling and sods law it went up as I did.
hi. does this type of ballast have a specific name or application? cheers!

Not really. It's just a 58W ballast which you can get at any electrical wholesalers.
They are used in Fluorescent lights.
it didn't like that!, try a shaded pole motor!!
