what transformer to use?

[chrisz]

i've got some LED lights that are supposed to be plugged into the mains, but I want to remove the pictured transformer and wire it into the main wiring circuit so it can run of a switch.

Where can I get a transformer for this, or what specification?

thanks

 

[breezer]

spec is on the transformer.

why not get differnt leights?

picture opf the lights? (postin pictures info, is in forum information)

put a plug on the lighting circuit. and no, im not joking. write on it, "max 5A"

would a socket not be better?

I could swear i wrote socket.

I could swear i wrote socket.

you did type socket, but you spelt it with the wrong letters, p-l-u-g

i know what it is, you have my keyboard, it makes spellin wromg

 

[chrisz]

I'd prefer to have it concealed and just use a switch, is this not an option? can I not get a transformer to replace this one?

 

[chrisz]

would this be ok?

yeah, why not.

Well this doesn't seem to work. Can anyone shed any light on this?

The first picture shows the controller that all the LEDs plug into, this has two wires which run to the transformer (second picture) this then in turns goes to the lighting circuit (or mains). When it didn't work on the lighting circuit I tried plugging it into the mains with a plug and the new transformer to see if it would work this way. It didn't, this would suggest that the transformer is not correct, can anyone confirm this, or am I doing something else wrong.

Thanks

The distribution board in MicroMark.

The new transformer is Hololite and is not a true transformer as it is providing a 12 volt DC supply

The correct Micromark transformer supplied with the kit may be providing 12 volts AC and the distribution board may require AC voltage to work.

If the Micromark transformer was supplying DC then the connector would be polarised and the instructions do not refer to it being necessary to observe polarity on that lead. They do on the LED leads.

hi, thanks for your reply. Can I get a transformer that will convert to AC instead of DC?

 

[bernardgreen]

Why not use the one that came with the kit. It is designed to work with the kit, it may have a safety device built into the transformer to protect the rest of the kit.

transformers do convert ac voltage to ac voltage. what you have is an electronic transformer, its pnly called a transfomer becuse it is transfomring the voltage down, but it also is rectifying it (changing it to dc)

as was suggested in the first place, why not use the one that came with it, yes i have read what you have said, but if you go and buy another transformer you will have spent a bunch of money needlesly. still, its not my money.

if its of any use, leds should not work properly on ac, they were designed for dc, bearing this in mind, i got some colour changing led lamps, and guess what, they wont colour change on dc, like you would expect they would, they will only colour change on ac.

my point is if you have the correct kit (as you have already) then stuff will work as it was desiged to work

I wanted them to work on a switch, located on a wall, not a socket with a plug.
