Electronic control gear
QUICKTRONIC for OSRAM DULUX L and OSRAM DULUX F, two-lamp version, long
QT 2x55,70/230-240
Page 2
- Pleasant, flicker-free light with no stroboscopic effect thanks to high-frequency operation
- Comfortable lighting with no distracting hum thanks to fully electronic operation
- No flashing or flickering; the electronic fault monitoring circuit disconnects defective lamps.
Economy:
- Depending on lamp type, 12%-52% increase in system luminous efficacy
- 50% longer life because the lamp is not exposed to such high stresses; longer relamping intervals
- Lower maintenance costs since there are fewer lamps and no starters to replace
- Longer life and reduced load on air conditioning systems because the lamps generate less heat.
Safety:
- Safety shutdown of the power supply to defective lamps
- Compliance with European standards for safety, operation and EMC
- Overvoltage protective cutout for short-duration voltage surges (DIN VDE 160) and for temporary overvoltages
- Greater fire protection because lamps operate at lower temperatures and luminaires can be constructed to meet EN
60598/DIN 60598/DIN VDE 0710 and DIN VDE 0711 standards
- Can be used in emergency lighting systems to DIN VDE 0108.
General:
- Supply voltage: 230V/240V
- Mains frequency: 0/50 to 60 Hz
- Lamp start: warm start within 2 s
- Radio interference suppression: to DIN VDE 0875/CISPR 15/EN 55015
- Mains harmonics: to DIN VDE 0712 Part 23/EN 61000-3-2/EN 60929
- Immunity to EN 61547
-Battery voltage may drop to 176 V. Lamps must be ignited at over 198 V however.
-Same luminous flux in ac and dc operation for QT 18W, 24W, 36W.
-80% of the luminous flux in dc operation for QT 40W, 55W.
-The luminous flux value is that for OSRAM DULUX L, the value for OSRAMDULUX F is 100 lm lower
-Approx. 0.1 s restart time after a changeover interruption lasting < 0.2 s.
