EcoSystem Digital Ballasts
EcoSystem compact ballasts provide high-performance
dimming for any compact fluorescent application,
including within an EcoSystem Lighting Control System.
EcoSystem compact ballasts offer 100%
to 5% dimming, providing both energy savings and
lighting flexibility.
Features
•Continuous,icker-freedimmingfrom100%to5%
•CompatiblewithEnergi Savr Node with EcoSystem
devices, GRAFIK Eye QS with EcoSystem connection,
PowPakdimmingmodulewithEcoSystem connection,
and Quantum systems, allowing for integration into an
existing/planned EcoSystem lighting control system
•Supportsstandard3-wireline-voltagephasecontrol
technology.
•Programmedrapidstartdesignensuresfull-ratedlamp
