240 to 60v LED driver

[gotoPzero]

Anyone know where I can find either this exact driver or one thats the same / similar spec?

I have checked JCC and its not listed. Used my best googlefu and still no joy. Thanks!

Meanwell might have something.

Lowest current is 300mA. I need 110mA CC .... I think. But thanks for the idea.

You want a constant current LED driver, but they seem to be 350 or 700mA rather than yours @ 110mA
Adjustable one here claims to do 90 to 180

That looks pretty good, set at 120mA the lamp might be slightly brighter than others if you have similar ones.

Cheers that looks like it might do it - is it an issue to be at the bottom end of the voltage range?

Yes as you point out I have others in the same room (8 total) so it needs to be similar.

Hopefully not an issue as the original should be well within spec? You could always swap in one of the others and measure the voltage across the output? It should just try to maintain 110mA and the voltage range is just a function of safety (not allowed too high) and efficiency/ design limitations at the lower end.

My thoughts too, the open cct voltage is 60v max but the original driver does seem a bit of an odd one though. It might the led lamp needs a higher voltage to drive the set current.

I think the OP needs to try the various settings, I would start at the lowest current and see how it performs.

I would suggest a phone call to technical support at JCC, explain what happened and see if they can suggest anything. You might find they use a similar spec driver with a later design of lamp, you might need to buy the whole lamp just to get the driver unit.
