The New Benchmark: HVLED101
Building on this heritage of excellence, the new HVLED101 represents the next generation of high power factor (HPF) flyback controllers. Specifically designed for professional and industrial lighting, it introduces:
- Enhanced power quality: High power factor (>0.9) and very low total harmonic distortion (THD) across a wide range of input voltages.
- Exceptional precision regulation: Advanced constant voltage regulation for maximum reliability.
- Smart protection: A comprehensive integrated protection suite (overvoltage, overtemperature, short‑circuit) to ensure long service life for LED lamps.
- Audible noise‑related operation: HVLED101 valley‑locking technology supporting no audible noise at light and medium load.
