Hi all!
I am facing an issue with dimming output, where I require an expert insight.
I have this project where Siemens Universal Dimmer (5WG1 527-1AB31) will be used. The dimmble LED in question is a chinese product. The facility is powered by a gas generator. I have been working with the same dimmer on other projects, but without this problem.
I have tested three different dimmable led samples on the facility (assuming chinese driver incompatibility), where the output of the LEDs were flashing/pulsing (constantly varying brightness between 400 to 500 lux level). The led samples worked fine when connected to grid or other generators (tested on other facilities). We have commissioned the Siemens universal Dimmers separately as Leading Edge and trailing edge to see the effects. The result is the same.
Can someone help me understand what is happening? I assume there must be some problem with the generator output. The issue appears only when dimmed.
Thanks in advance.
