Electronic Control System for Xenon and Mercury Lamps with onboard Igniter



Electronic Control System for Xenon and Mercury Lamps with onboard Igniter


  • Power supply for metal halide or xenon filled short arc lamps
  • Designed for xenon and mercury short arc lamps rated up to 100 W
  • Output power customer selectable by DIL / 16 step-switch
  • Capable to drive lamp voltages ranging from 8 to 45 V
  • Certified by OSRAM and USHIO
  • Input voltage range from 90 V AC to 264 V AC, power factor corrected line input, built-in EMI-filter: meets CE and FCC part “A”
  • μP controlled, digital power management with high output stability over lamp lifetime
  • Output short circuit protected
  • Galvanic separation of lamp output and line input, thermal shut off at 90°C
  • Indication function for end of lamp life selectable and shut off for lamp fail parameter
  • Customer adjustable to less than 0.3% rms light flicker at all frequencies uninterr.
  • Default light stability with modulation of less than ± 3% during full wave supply interruption
  • Auxiliary regulated 12 V / 0.2 A output for fan drive (available only when lamp lit)
  • Flexible design: new lamps and functions adaptable by software
