Problem with a three-ring LED chandelier
Hello. A few days ago I bought a new chandelier for my living room. The chandelier consists of three rings with LED strips. The length of the large ring is 2.512 meters, the middle ring is 1.884 meters, and the small ring is 1.256 meters. The chandelier works in two positions (2 phases, 1 zero). In the first position, a large ring is lit, and in the second position, the LED strip of the middle and small ring is lit. On the power supply unit of a large ring it is written: Input: AC180-260V 50/60 Hz. Output1: DC125-195V 250 MA + -5%. Tc: 75 ° CTa: 50 ° C 7/11. For the medium and small rings, the power supply is one and it says: Input: AC180-260V 50/60 Hz. Output1: DC158-210V 250 MA + -5%. Tc: 75 ° C Ta: 50 ° C 7/9 The thing is that when I installed the chandelier the middle and the small ring blinked strongly. And the big ring shines steadily. I changed the laces, but the problem remained. That is, again, the large ring shines steadily, and the middle and small rings flash strongly. Moreover, when I check them on a regular outlet, all 3 rings shine normally. I myself am not very good at electronics, and the electrician also does not know the cause of the problem. I beg you to indicate to me the possible causes of this problem. Thank you in advance.

If LED strips are not designed to work directly from the network, then they can not be connected without converters, as they will fail. If you checked on a conventional outlet with the converters and the chandelier is working properly, then the problem is in the area of the wiring that powers this chandelier. In this case, there may be no contact in the junction box or there may be a break in the core somewhere in this wiring section. You also need to check the integrity of the circuits and the reliability of the contact in the chandelier itself. If the wiring is OK, the circuits in the chandelier are integral, then the cause may be a malfunction of the converter, which feeds the middle and small ring of the chandelier.
