Concealed Power Supply

[Charlie_]

I need to get a 110v supply from a wall, through a door frame and into the glass rebate of a door..
Has anybody successfully done this?
I want it to be concealed so the little boxes with flexible conduit are no good.
I’m thinking of using power transfer hinges.
It’s to power smart glass in the door..
The windows are easy enough as they are all stationary.

 

[James]

there are so many types of transfer hinge. can you post a link?

 

[Charlie_]

Yes will try to.. The ones I’ve used previously are for elv supplies so struggling to find one avtually rated for 110v

there are loads of spring contacts out there but not suitable for 110v
you could transform 110 down to 30 outside the frame and then step back up inside the door but its a messy solution and the current at 30v might be higher than the contacts are rated at.

smart glass in a door???? beam me up scotty.

buy a mirrored door, sometimes the reflection will be smart?

Not got much room to play with inside the glass rebates..
The glass comes with 2 thin tails which I will twist,solder & heat shrink onto the supply legs..
The load is about 10 watts..
The other option I was thinking of was how to concertina the wires up in the frame rebate when the door closes

is the glass put in yet ?

No not yet..

 

[James]

something like this might sort you out.

No not yet

good ,the best way is to extend the cable through the metal frame to the transfomer .is the frame in yet .

That looks like a good and simple solution.
I shall investigate further

Timber door and frame..
Transformers located elsewhere..
I have wired supplies from transformer to door frame location

some times the smallest ideas are the best ideas ,wood you like me to send details to a beaver .lol.

the spec has no voltage limits listed. I am presuming it is just the conduit with no cable inside. but it also fails to list the internal diameter so its not a guaranteed fix but might be suitable.

Smart glass? Is that a pint one that fills itself

i'm lucky enough to have a wife who sorts the pesky filling operation. I deal with the emptying.
its a 50/50 split of workload (in my mind)

What smart door need 110v supply seems like a odd voltage for Uk application. Need a bit more detail/photos of planned install

 

[telectrix]

or this, maybe only rated @ ELV though.

Its not the door that is smart, the 110v is for the actual glass.. SmartGlass is just one of the brand names given to it. Others go by the name of Intelligent Glass, Switch Glass..
The last one being my favourite name; as that is what it is. Nothing smart or intelligent about it, just a gimmicky name to hook people in.
Basically it’s layers of glass with liquid crystal in between the layers.
Goes from opaque to clear with voltage supplied.

 

[StephenRowley]

Surely they all ready have there own solution to this problem

 

[Charlie_]

This is their ermmm solution
Not really suitable for a high end job unfortunately

Lads have just done one in a top of the range, ongoing job. It's basically a glass outside wall of a bathroom which changes from clear to opaque when in use. Mind blowing spec to the job.

You can also vary the voltage to the glass to alter the opacity..
Which brand did you install?
Was it also 110v?
The job i’m currently involved in has it specced up for an orangery.. I’ve also used it for offices and between gyms and pools.

 

[pirate]

Charlie, you just answered a question i was about to ask...ie can you vary the opacity? I presume this is the case for all such glass?
I have a project for which this application would be perfect, so could you link me to a preferred supplier to save me hours of research?

 

[DPG]

Bit of a bugger if the power fails while you're starkers in the bathroom. Or does it fail safe?

Depends on who is in there

Hahaha..
It fails safe - power on = clear glass
