Transnformers buzzing when Channel off

I've got some 50w LV lights in the office (not using Aruba trannies).

When the channel is off, it buzzes ! If I flick the MCB for that channel, no more buzzing.

This would seem to indicate there is some leakage of power even when the channel is off??

 

I presume you are talking about dimmers?

There is voltage at the outputs at all times. Even when the dimmers are at 0%. So there is some very minor leakage.

Why the tranny's are buzzing at that level though? are they leading or trailing edge?

 

LOL - the voltage is not that "minor", as anyone who has accidentally touched the output can tell you. I think it's more like 240V leakage, but only a minimal amount of current available

As Nobes says, in order to solve this we need to know the exact brand and also the quantity of trannies on each channel.

 

come now, it doesn't give you that much of a boot

but yes the voltage is 240v but the current is low.

 

Com'on Nobes, if you accidently touch it with your tongue - man it hurts!

 

How would touching it with your tongue be accidental?

 

What ever floats your boat Josh...

 

Now you are starting to worry me.

Although a good idea for an Apprentice.

 

Using your teeth as wire strippers at a guess.
