Over Supply of power ?

hi

i am doing maintenance work on a c-bus 1 and c-bus 2 combined installation which is spread out and located that there were way too many power supplys

there were 6 connected to one network and also toolkit database shows that there is 1028mA being used but only 1000mA being supplied
only 3PS are connected now as there is 600mA being supplied from 3 c-bus2 12 channel relays , the thing i want to know is why i cannot see on toolkit which relay is producing the supply because i cannot find a hidden 3 relays and wish to know if they are producing the additional 400mA to make the 1000mA of supply that toolkit tells me that overall is being supplied without power supplys

would like to know to log down and why i cannot find why there isnt a automatic calculation of total current supplied to circuit ?

could it realy be that hard to count power supplies in the software toolkit ?
im sure it would help a few people out when fault finding

 

When scanning a C-Bus network, Toolkit cannot determine which units do and don't have C-Bus network power supplies built in.

When Toolkit scans a network, it does a "best guess" as to the catalogue number. For the calculator to work accurately, you need to manually enter the exact catalogue numbers of each unit. It will then accurately calculate the network parameters.

Also remember that a stand-alone power supply does not show up in a network scan at all.

 

Quick question on this note: would it be possible to disable the built in power supply in a relay or dimmer without voiding the warranty?

 

No.

Disabling the power supply would require a good knowledge of the circuit and using pliers or a soldering iron

It doesn't really matter if there is a bit more power capacity than you actually need. The power supplies only generate as much power as is required - none is wasted. The important thing is to have enough power but to stay under 2000mA limit.

 

Ah, good to know that my system is not putting out it's full capacity when it only needs 1/3 of it. I really over-budgeted on my power and did not want to see it being wasted (very important for this particular project).

If you happen to know, could you tell me how much power a dimmer unit or relay with a built in power supply should be using when all its loads are off?

 

It depends on how much power it is supplying to C-Bus.
