ᐅ Multiple diode strips connected to a transformer/controller

Hello everyone,

I recently assembled a Besta / Framsta combination. I have a total of 6 colored Diode LED strips for it. A 2-meter (6.5 feet) tall salesperson in the IKEA lighting department assured me that I can connect 2 sets of 4 strips per transformer, so two complete strips. Beyond that, the power would just drop too much (my own test: 3 or 4 strips also work, but some colors seem to draw too much current and then they just start blinking).

So now I have 3 transformers with 3 color controllers each behind my Framsta, and I have to report: The transformers get incredibly hot and after about 30 to 60 minutes, two of the three transformers shut down. Probably a thermal cutoff. It’s always the same two; the third one runs like a Duracell bunny.

Does anyone know this? Is this normal? Do I really have to use 5 transformers and 5 color controllers? You’d never pick the same color exactly each time, plus it’s quite annoying...

Any ideas?





Thanks in advance,

Philipp
