.: Technical Information

Physical Data:
  • Firm metal case IP20 up to IP65; light weight design; base plate with    slots for M4 bolts
  • Push-in terminals with lever-button accepts up to 2.5mm2    solid/stranded wire
    • Electrical Data::

     Input:

  • Wide range of supply voltages - AC 198V-264V / 50-60Hz
       DC 198V-254V
  • No inrush current
  • Constant power consumptio
  • Power factor > 0.98 (no need for correction)
  • THD-A < 10% (clean power consumption)

    • Output:

  • Ignition: 4kV pulses (max. line load capacitance 250pF)
  • Stable lamp power output independent of supply voltage or lamp voltage
  • Lamp operates at low frequency square wave (83Hz)
  • Low SPR
    		•

    Technical Features:
  • Smart ignition regime - computed ignition attempts and shutdown are implemented according to    actual conditions
  • Innovative design allows for exceptionally lowballast losses
  • Same ballast can operate all types of HIDlamps: MH (quartz &ceramic), HPS and Mercury lamps
  • Lamp operates at low frequency square wave(83Hz):
       - Prevents acoustic resonance
       - Flicker free
       -Improved lamp longevity and lumen maintenance
       -Prevents partial glow discharge in the lamp and high leading voltage peaks
  • Broad operating temperature range: -20ºC< Ta < +50ºC
  • Power Factor > 0.98, registered patents for active power factor correction
  • Negligible inrush current on activation (prevents fuse/CB tripping)
  • Complete digital control achieved by a single state-of-the-art microprocessor allowing for:
       - Fewer control components
       - Greater flexibilityinqualitycontrolformulas
       - Greater control over data and program variables
       - Easily upgradable programs
       - Lower power losses in comparison with other brands of ballasts with square wave lamp current    operation.

    • Safety Features:
  • Internal temperature control protects the ballast
       - Output power reduction when internal temperature rises above85°C
       - Shutdown when internal temperature rises above 90°C (4restarts after cooling)
  • Protection against lamp faults (EOL): DC condition,(rectification),cycling,ignitionfailure,NoLoad    protection,short-circuit at lamp terminals, external arc, high/low lamp voltage. (Shutdown can be    reset)
  • Protection at abnormal mains conditions:
       over-voltage, under-voltage and network interference(EN61547)

    • Controlling and Monitoring:
  • Internal data accumulation and external communication facilitate real-time monitoring and/or    periodical analysis and diagnosis
  • Lamp monitoring: end of life, defective lamp, etc.
  • Various communication protocols (input from control device) DALI & PWM
  • Automatic dimming can be set to respond to a programmable schedule (multiplex scenes) or    variable conditions, such as occupancy and daylight harvesting
