Hello all,
I have a big problem with the dimmer.
The lamps that connect to the dimmer flash irregularly, even in the absence of the signal (DMX Set all outputs off (--------)).
All outputs are equipped with inductors [see P.S.].
The lamps are all 60W and dimmable.
If I connect 4 on one channel and the other 4 on another channel (two channels so you have loaded each of 240W) does not change anything, so it should not be a problem too low load per channel.
If you unplug the "load-board" of a channel from the "control-board", the channel stops blinking, so it's not a problem of automatically triggering the triac.
At first I thought about a noise problem in the power line, so I put a line filter at the dimmer.
Then I thought about a problem in the "synk-board". I rebuilt it with all new parts but nothing has changed.
If at home LVH imposed a 2% the effect disappears, however trying it in another place the effect does not disappear even with a LVH of 10%.
Do you have any idea?
P.S.
1. I used the TRIAC BTA25-600B.
2. I used these inductors:
Toroidal chokes Inductivity 1 mH 250 V/AC 16 A
