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,flicker-freedimmingfrom100%to5%•CompatiblewithEnergi
Savr Node with EcoSystem
devices, GRAFIK Eye QS with EcoSystem connection,
PowPakdimmingmodulewithEcoSystem connection, and Quantum systems,
allowing for integration into an existing/planned EcoSystem
lighting control system
•Supportsstandard3-wireline-voltagephasecontroltechnology.
•Programmedrapidstartdesignensuresfull-ratedlamplife while
dimming and cycling.
•Lampsturnontoanydimmedlevelwithoutflashingtofull
brightness.
•Lowharmonicdistortionthroughouttheentire dimming range.
•Frequencyofoperationensuresthatballastdoesnotinterfere with
infrared devices.
•Inrushcurrentlimitingcircuitryeliminatescircuitbreakertripping,
switch arcing, and relay failure.
•Ultra-quietoperation.•Protectedfrommiswiresofanyinputpowertocontrol
