An ECG for use outside in professional lighting installations with high intensity discharge lamps. With 3DIM functionality (StepDIM/AstroDIM/DALI), lightning protection up to 10 kV, an energy efficiency index of A2 and luminous flux factor 1 compared with CCG operation. You can use it outside in luminaires with protection of IP54 or greater, and in luminaires of protection classes I and II.With excellent thermal behavior at very high limit temperatures tc and ta; high surge protection (up to 3 kV (L-N) / 4 kV (L/N-PE); energy savings of up to 30 % compared to CCG operation due to 3DIM functionality (except PTo 35) and the assurance of automatic lamp shutdown in the event of defect.
