A few days ago my milling machine Optimum BF20 Vario started making a pulsing noise similar to interrupt for a moment normal noise after pulsing, then normal, and so on ... At the same time the built-in lamp that receives power from the same source shimmered.
Thinking the cause was the speed driver board I bought a new one and today I installed it.
When I start the milling machine, being very close to the electronic boards, I hear a very low noise that reminds me eggs to be fried and, moreover, the pulsing behavior remains.
Apparently the electronic board speed control is not to blame.
In the documentation of the milling machine, Optimum (the distributor) calls the power board "relay board".
I identify in it a transformer but I am not able to identify any other components.
In the board I can read can read the following: 608BD / 230V 0710300050 P / b ROHS 05/25/2007
Searching the web I didn't found any reference to a plate with those sayings.
I did further research with other criteria but was not successful.
Will someone, among the distinguished participants in the forum, can give me some clue or guide?
I didn't find the right solution from the Internet.
