EcoSystem Bus Supply
An EcoSystem lighting network containing more than
one ballast, module, or driver requires an EcoSystem
Bus Supply. This supply powers one or two
independent EcoSystem buses with up to 64 ballasts
or ballast modules per bus.
Features
•ProvidespowerforeitheroneortwoEcoSystem
buses, depending on model.
•Reprogramssettingsofreplacementballasts
automatically.
•Maintainsredundantmemoryofballastandmodule
