Active Power Factor Correction

With the internal active harmonic filter, power factor of Hoye electronic ballasts is higher than 98% and total harmonic distortion is reduced to less than 10%, which is far beyond the limits of IEC 61000-3-2.

Electromagnetic Interference

The electromagnetic interference of Hoye electronic ballasts is further suppressed with the improved circuit design technologies. EMC performance is superior to most other products in the market.

Input Regulation

With the internal voltage regulation circuit, the luminous flux is unaffected by mains voltage. It provides a comfortable and stable light source for the environment.
