Information About H3DT521CU110
The H3DT521CU110 belongs to the Hi-Lume 3D series of Lutron electronic dimming ballasts, engineered for superior light quality and efficiency. Featuring proprietary full-range dimming technology, it supports one F21T5 lamp with a programmed rapid start for extended lamp life. The ballast operates at a high frequency of 42 kHz to eliminate flicker and audible noise, maintaining a Class A sound rating and power factor of 0.95. With UL, CSA, and FCC approvals, it is ideal for high-performance indoor lighting requiring precise, smooth dimming control.
Key Features:
- Continuous Dimming: Provides full-range flicker-free dimming from 100% down to 1%.
- Programmed Rapid Start: Ensures optimal lamp life and reliable starting at low temperatures.
- High Efficiency: Operates with a 0.95 power factor and 10% maximum THD for stable performance.
- Wide Input Voltage: Accepts 120, 240, or 277 VAC for universal installation flexibility.
- High-Frequency Operation: Runs at 42 kHz to reduce flicker and noise.
- Thermally Protected: Class P ballast with a maximum case temperature of 75°C for safety.
- Compact Form Factor: 18" length for easy integration in fixture housings.
- Certified Performance: Meets ANSI, UL, CSA, CEC, FCC, and RoHS standards for quality and compliance.
The H3DT521CU110 delivers the reliability and precision required for professional-grade dimming control in architectural and commercial fluorescent lighting applications.
