EB 2,5/4 High Speed
Electronic ballast for use with 2500 W and 4000 W Metal Halide Lamps
  • Available for daylight lamps of all well-known manufacturers.
  • CCL – Compensation of cable losses between ballast and lamphead (in connection with suitable lampheads).
  • Electronic detection of the used lamp types 2500 W and 4000 W
  • Lamp power constant controlled for steady light quality independent of line voltage and of the age of the bulb used.
  • Flicker free operation by use of 75Hz square wave current for use with standard frame rates
  • High speed operation modes with 300 Hz and 1000 Hz square wave current for digital cameras with high frame rates.
  • Autoscan function for the high speed operation modes: The ballast automatically searches the optimal operation frequency for the used lamp to operate with up to 3000 fps.
  • Additional “low-noise” modes (50Hz/60Hz) to reduce the noise that might occur in the lamp head.
  • Typical light ripple max. 3%.
  • "Arc Control" to prevent unintended resonance arising inside bulbs of different designs (75Hz and "low-noise" operation).
  • Dimming in range of 50 - 100% of nominal lamp power.
  • With active line filter (PFC) for minimized apparent power and reduced disturbances of power supply network.
  • Large range for input voltage 190 - 250 V~ (automatic switching).
  • Optionally with additional input voltage range: 100 – 130V (automatic switching).
  • Protection against line overvoltage and overtemperature.
  • Lamp outlet protected against no-load conditions and short circuit.
  • Solid aluminum construction with outside heat sinks.
  • Very silent due to temperature regulated fans.
  • Extended 3 channel DMX remote control (on/off, dimming, operation mode).
