LOXONE-DMX-PWM - Flickering of the LED strips after a few minutes of operation

Hello everyone.
Well, I would like to describe a problem.
I have eight led strip circuits connected to a LOXONE DMX-PWM controller (12V-24V 3X3 CHANNELS). The Pwm controller is powered by 12v DC and the strips are connected to the led amplifiers (due to their high power) via transformers with the appropriate power (20% reserve).Transformers with a power of 150,250,320
After switching on whichever circuit and whatever intensity the leds are at, after a few minutes they flash (approx. 0.3s) at full power and continue to flash every few minutes.
Switching on all the circuits, regardless of the intensity, the flashing is on all the circuits separately only in time intervals and sometimes two or three circuits flash at the same time.
Perhaps someone has an idea about this?
Please give me an answer on this matter.
Regards

There can be several reasons for this. Chinese power supplies of poor quality, a faulty LED module, a faulty DMX module. I don't know Loxone personally, but for me the use of DMX protocol in building automation is a misunderstanding. It's an outdated protocol developed for stage lighting, and it still works well there, but I wouldn't implement it at home. Communication is unidirectional, so the controller never knows if the signal has arrived without error. If the cable is unshielded, the controller is in one place, the DMX dimmer module in another, and the cable goes past some device that generates some kind of pulse, this can also be the cause. Good quality shielded cables are used for DMX, usually low capacitance audio cables.

The only thing that could be the cause is the lack of a shielded cable between DMX and PWM
Thank you for your reply

Hello as far as I remember there is only 50W per channel maybe you have exaggerated the watts.

Each channel goes through a 240w amplifier

You were writing about transformers ...- transformers are not used for leds but power supplies....

These are power supplies for led tapes

Basic diagnostics are in order. Unplug the amps and connect a few metres directly. Are they still flashing? If not, you have cables and amplifier to check. If yes, then the DMX module should be replaced. They have recently released new models of controllers with RGBW.
