Key features
  • System architecture based on transition mode boost PFC, half bridge LCC and synchronous rectification (full bridge)
  • 270-480 VAC input voltage range
  • Output can be configured in constant current (CC) or constant voltage (CV) mode:
    • 300 W maximum O/P power rating
    • CV mode: 48.5 V ± 1%
    • CC mode: 6.25 A ± 2.5% with voltage drop from 36 to 48 V
  • Peak efficiency >93.5%
  • Power Factor > 0.9 for load > 33% of max. load of the input voltage range
  • THD < 20% for load > 25% of max. load of the input voltage range
  • Dimming control in CC mode configuration:
    • 0-10 V control
    • 1% resolution
    • analog dimming
  • Soft start
