Modern Tridonic Issues

[Kev]

The difference with those combo ballasts is that they have a lot more circuitry in but were all U.K. made and yeh that’s the cheap piece of shit tridonic basic

It’s a shame they lowered to making those, even the pcb material looks cheap, and thorn went and used them in the PP’s!
Interestingly though the fixing centres on the 1x36W one are the same as a 36W choke so you know what will happen when it fails

Yeah I like that the PC combos are UK made, the construction also looks decent too.
The PC DD Pro 2D ballasts are also UK made (guessing the same factory as the combos), don’t know if those are any good too?

Yes they are all made in the former atlas factory!

Good to know, it's also nice to use British made ones too!
I suppose they have stopped making them all now though, all the data I could find for them has "phased out" written across the sheets.

I had some modern tridonic issues yesterday, two brand-new 1X 49W weather packs fitted them, both came on fine then one went out then the other. China ballasts fucking crap

Indeed absolute junk, what did you replace it with? They are not even worth installing if they are going to do that tbh.
I've found the older version with the open ended cases to be better, a least they actually get to the end of the first tubes life in my experience.

The Thorn 58W 2 tube fixture that I rescued from the village hall in Caversham, Reading, has a failed Tridonic ballast of which I am going to replace with a non Tridonic electronic ballast that has pre programmed start (instant start electronic ballasts are )

And also had a magnetic ballast from the same make short itself out that was in a Fitzy 40W fitting

A Philips HF-Performer would probably be the best bet, if not then an older Osram quicktronic. Have you got a photo of the failed Tridonic? In what way did it EOL?

Uploaded the pic of the failed Tridonic magnetic ballast in my Fluorescent gallery section
