Information About EC3DT4MWKU1S
The EC3DT4MWKU1S is part of Lutron’s EcoSystem® Type K digital dimming ballast series, built for high-performance CFL lighting control. It operates on universal voltage (120/220/240/277 VAC) and supports a single 4-pin compact fluorescent lamp. Designed for bottom exit stud mounting, the unit features programmed/rapid start technology and is compatible with EcoSystem Digital Bus, GRAFIK Eye QS, and Quantum systems. Its 0.95 ballast factor ensures consistent light output with reduced harmonic distortion.
Key Features:
- Universal Voltage Compatibility: Operates with 120, 220, 240, or 277 VAC at 50/60 Hz.
- Dimming Range: Provides continuous flicker-free dimming from 100% to 5%.
- Control System Integration: Fully compatible with EcoSystem Digital Bus, GRAFIK Eye QS, and Quantum.
- Start Type: Programmed rapid start preserves lamp life and enables instant-on to any dimmed level.
- Low Harmonics: Maintains total harmonic distortion below 20% for cleaner power usage.
- Quiet Operation: Inaudible in 27 dBA ambient, suitable for noise-sensitive environments.
- Thermal Protection: Class P rated with max case temperature of 167°F (75°C).
- Compliance & Safety: UL Listed, CSA certified, FCC compliant, and meets ANSI/ESD standards.
The EC3DT4MWKU1S delivers the reliability and precision required for efficient and flexible fluorescent dimming applications.
