5101R vs L5504AMP

Dear all,

in a hotel project, we have to dim a channel of fluorescent lamps (approx. 10 pcs) in every room.

Since every room is a independent network

1. I can't use L5504AMP because I don't have a spare relay channel to turn off the circuit
2. I can't use only 1 pc of 5101R because the 5101R has the ability to drive maximum 2 ballasts...

Any ideas for the most economical way?

 

You don't really have any other option.
You will need to use the L5504AMP with a relay channel from where ever you can find a spare.
Does all ten lights have to turn on together, maybe you could talk them into breaking up the lights into 4 circuits that way you could justify the cost of the units.

You could try using 5 x 5101R to control the ten lights (two lights of one relay), not sure how that will line up with cost instead of using the L5504AMP
