Philips fluorescent voltage converter

Found and buy it at a second hands store. I think this is made for fluorescent lights in train, tram and/or busses. There are 3 Ballasts on this unit (one on the other side).
If somebody know more about this please let me know..

Jup, I think so and it’s running on DC voltage. Must try to find my 24Vdc supply so I can test this thing..

I wish I could find something like this but only for input voltage area of 44-58v dc. I could use it in my dc-system.

Why not hook up a pair of 12 Volts of Lead-acid batteries in series to see what happens

Pretty, please no more Chinese failure.

It seems to be a late model with technology already perfected. First transistor DC to AC converters were already in 1958:
