Maybe the title could be better chosen.

Hello,

I have a 33V 0.8A constant voltage led driver (see picture below, the item no. is GL-1201C-8 if that can help) which no longer works. I searched online but can't find it for an acceptable price.

I understood the difference between a constant current driver and a constant voltage driver but I can't find out if I can use a driver with slightly different specs like this one (summary: output 36 W, 36 V DC, 1 A)

Can you help me on that?

And the second question is can I use a constant current driver instead of a constant voltage driver? I think I can't in this case, is that correct?

The picture is here.

  • \$\begingroup\$ Q2: Depends. Is the operating current of the constant voltage load within the adjustable range of your CC supply? If you are uncertain - don’t. \$\endgroup\$ – winny Jul 24 '20 at 16:24

  • \$\begingroup\$ It depends on how your LEDs are wired. If constant current of 0.8A was used, then you need another CC 0.8A, not a CV. \$\endgroup\$ – Marko Buršič Jul 24 '20 at 17:59
