Comfort Cabinets

[idheath]

What are the options PSU wise when powering a 2nd cabinet (either an EN01 or EN03) when this cabinet only has UCMs in it.

I can see in the UK that the EN03 is available with a transformer but I assume that\'s intended to be connected to the mainboard for rectification/regulation etc.

You do not need the transformer for UCMs
I dont know if the EN03 is already with the transformer bit it does not cost  very much,  so you can leave it connected or remove it

EN01 is smaller 350 x 310 x 95 mm but it may not be stocked in the UK, but not sure about that

Both have some mounting locations for UCMs

What I mean is I need a 2nd cabinet to cater for my extra UCMs etc because there\'s no room in the original cabinet.  I also assume that the existing PSU (in the original cab) won\'t be able to power everything.
So I assume I need a 2nd cabinet and that this cabinet needs its own PSU (ideally along with battery backup).
My query is what\'s recommended in this instance.
Thanks.

I went through a similar exercise recenty and purchased an en03 and mounted it.  I also thought that whilst I was at it I might as well buy a slave as well to cater for future expansion as they are pretty cost effective.   I then purchased a power supply from cytech and a backup battery from maplins.
One thing to watch out for that hopefully cytech have fixed since was that the power supply didnt come with a fused connection block which they sent me shortly after.
I have my en03 populated with 3 extra ucms and doesn\'t seem to matter if I power from the slave power supply or directly from the rs485 bus powered from the main unit via ka/kb.
Hope this helps.

If your 2nd enclosure just holds UCMs, these can be supplied only from Comfort or the Slave. Only Comfort and Slave have built-in battery chargers to charge a battery

There is no separate PSU in Comfort

But if you just add a few UCMs these should not need an additional PSU as they do not require much current

Ah thanks, I see.  
Is it correct that I should avoid drawing more than 850mA (12V DC) from the PSU and the best way to check is to place an ammeter in-line with the battery and fail the mains supply.

Thanks, I current have a non-standard \"Comfort Home Controls\" case containing just the LEM03 and an ADM01.  My existing UCMs (x2) are external and I\'d like to get everything into one enclosure if possible.  I plan to have the following in addition to the mainboard.

• ADM01
• LEM03
• UCM/Serial
• UCM/Eth
• UCM/Z-Wave
• UCM/GSM

So I\'m thinking of getting a EN01 or EN03 to replace my existing enclosure, I\'m just not sure whether all of that will fit in either enclosure.  Also do you think I will be able to transfer the transformer from the old to new case?

Thanks again

The ucms and lems are all the same size 108 x 88 mm
6 of these +Comfort will not fit into one enclosure

It is better to get another EN03 to fit the extra modules and have extra room to play around

You should not need an extra power supply
