Multiple diode strips on a transformer/regulator

Hello community,

I have a Besta / Framsta combination that I assembled today. For this, I have a total of 6 colored diodes LED strips. A 2-meter tall salesperson in the Ikea lighting department assured me that I can connect 2x 4 strips per transformer, so two complete strips. After that, the power would simply drop too much (personal test: 3 and 4 also work, but some colors apparently require too much power and then it just blinks).

So now I have 3 transformers with 3 color controllers each behind my Framsta and have to realize: The transformers get extremely hot and after about 30 - 60 minutes, two of the three transformers fail. Probably a safety shutdown. Always the same ones, the third runs like a Duracell bunny.

Does anyone know this? Is that normal? Do I really have to use 5 transformers and 5 color controllers now? You never hit the same color then, and it’s annoying too...

Any ideas?





Thanks in advance,

Philipp

You're a bit reckless, aren't you???

Take a look at the transformer and see how many watts are listed on it, then check the wattage on the light strips.
If that doesn't mean anything to you yet, then please keep your fingers off such things. You're crazy.

Why would IKEA include a transformer for 4 light strips that provides power for more than 4 light strips permanently???

Please have an electrician handle such things.

How much I love such charming answers...

1. I explicitly asked the expert, there was no reason to doubt his statement.
2. The power supply says 0.5 - 5 W, 4 strips alone are supposed to draw 6 W. So basically something doesn’t seem right.

I didn't want to offend you, but...

1. Employees at IKEA are not electricians.
2. It's your apartment and you can't hold the employee responsible for it (not even in court).

The predecessor says: 0.7 watts per white strip and 5 watts on the transformer. That makes 7 strips. I don't know what the rating on the colored ones is now, since they are installed in a way that I can't reach them. But I have approximately the same number in mind. Do the new ones have that much more wattage???

Hello community,

I had the same problem combining colored Dioder LED strips and finding out that the plug-in power supply is designed for a maximum of 4 LED strips. Fortunately, the power supply seems to have a thermal overload protection because mine shut down cleanly due to overheating when overloaded and worked again after cooling down. I had a total of 4 Dioder colored LED strip packages with 4 plug-in power supplies and 4 dimmers for a 4x Framsta panel, which is actually a no-go for operation...

First of all, a reminder that all electrical matters should be handled by a qualified electrician with the appropriate expertise and responsibility...

I connected 4 Dioder color LED strips together and connected them with the cable to the 4-way splitter. Before that, I tapped into the cable connection from the 4-way splitter to the power supply and measured it. The connection is a 2-wire cable with 0.75mm² cross-section, one wire with brown and one with blue insulation. The plug-in power supply supplies 12Vdc, with plus on the brown and minus on the blue wire (caution, reversing plus and minus probably leads to the failure of the entire electronics...). The total 16 color LED strips need a maximum of 1.6A at white light corresponding to about 20W, so 1.25W per strip. By the way, blue light consumes the least power.

Then I said goodbye to the warranty and cut off the plug-in power supply, afterwards I connected a 30W furniture built-in transformer with 12Vdc output (available from electronics mail order dealers). The only component that might be more stressed than intended in this construction is the board in the 4-way splitter, but I couldn't detect any heating in the splitter in my setup. With this, I now have a control unit to operate the entire panel without the power supply being overloaded.

The only element that might be more stressed than intended in this construction is the circuit board in the 4-way distributor, however, I have not noticed any heating in the distributor on my end. With this, I now have a control unit to operate the entire panel without overloading the power supply.

And what about the control unit? I once wrote to IKEA in Sweden about it. Unfortunately, they were also unwilling to research deeper technical data. Unfortunately, you can't get in touch with IKEA of Sweden at all. They probably also fear liability with every statement in case something does happen.
