This week I nearly learned a hard lesson re this!! (using a Lutron RA2 inline dimmer to control 6x 700ma 13w LED fittings)
So I thought 6x 13w=78w- thats fine its well within Lutrons stated 150w of LED load.
But after having issues with the dimmer- Lutron told me it has a 1amp load max. (6x 700ma= 4.2a so its too load)
But I put my clamp meter on the line cable coming out the dimmer when the 6no lights were on and it was only pulling 0.3a AC (78w/230v=0.3a)
What is the correct way of working out current when in comes to DC lighting?
So I managed to split the circuit into 2x 3 fittings and the driver had dip-switches to change the ma output- so I ran them all at 250ma (so both Lutron dimmers with 0.75a load and so far so good)
I am seeing more and more 350ma/700ma/1050ma LED fittings on the market- but how are they being controlled with dimmers?
For example:
say if they was 10x of the above on one circuit (14w, 1050ma)- how can it be controlled as one circuit?
This can handle the wattage but can it handle the current? (rated at max 2.2a)
Cheers
