CBus power requirements

In our country power standard is 220V +- 10%

From years of experience we see now, that with 207V mains voltage and lower system stops working correctly. Is it a subject to work on for Clipsal or should we continue using additional stabilizers?

 

Does it stop working because C-bus stops giving network power or does it fail to provide functions in the output channels ?

 

From mine expirience switches usually stop working. Some other times although the led gone on-off nothing happened. Also lights turned off (not all).
In one particular project I had, one phase (the one that fed C-Bus) often reached 198V. When I changed the feeding phase everything returned to normal.

 

C-Bus side starts working unpredictable. Stops working in fact.

Mains side control is ok

 

So I would suspect that the power supply for the data network is the part of the system which needs to be regulated or modified. I know nothing about this voltage problem but if the data network fails then everything is unable to operate.

Naturally I would be irresponsible if I suggested a supplementary power supply (just for voltage regulation) not from Clipsal.

 

No, other power supplies do not work with C-Bus. What we do is additionaly stabilize voltage, which is quite not good.

Have you tried calculating the overal C-Bus "bus power supply" for your whole C-Bus network? If I am not wrong the whole C-Bus network should not exceed more than 2A for all devices? If ok, maybe just test out with 1 x more C-Bus Bus PSU to nearing 2A?

Maybe you may have just enough C-Bus Bus power for your overall network; probably not a good idea if the supplied AC drops and so does your corresponding Bus power? So maybe adding additional Bus Power might be a good idea but not exceeding 2A overall.

It's good that you have provided additional AC provisions for power stabilization. Just make sure you are getting constant voltage by this method.

We also faced this problems in other countries whereby getting stable AC is a luxury.
