Exlux 6000 tried & proven technology has just been made better # Integration of a newly developed generation of electronic ballast with two "End of Life" (EoL) protection circuits according to DIN EN 61347-2-3 and IEC 60079-7 Ed.4 (draft) EoL test 1: Asymmetric pulse test EoL test 2: Asymmetric power test # Enhanced plant safety due to 2-channel electronic ballast, only the defective lamp is switched off # An integrated DC switching relay makes it easy to incorporate in the emergency lighting system (automatic switch over to DC power) # Increased service life is the result of improved UV stability of the light fitting's housing # Simple and versatile installation and maintenance of the light fitting # Selecting the right lighting element is the key to reducing maintenance and operating costs - That's why the electronic ballast is specially designed for use with fluorescent lamps which have a longer service life # Significant savings are achieved through the usage of ballasts with energy classification EEI=A2 Operation-proven technology guarantees a very high degree of plant safety An investment with a future – made possible by continual technological development End of Life EoL phenomenon During the operation of fluorescent light fixtures, the electron-emitting material on the electrodes is consumed. This has the consequence that the energy to release the electrons is increased, and this, in turn, can lead to a higher voltage drop at the electrodes of the fluorescent lamps. Since the electronic ballast functions as a constant current source, a higher voltage drop results in a power consumption increase. This produces a rise in the surface temperature at the lamp tube ends. The temperatures may exceed the limit values specified for explosion proof apparatus and thereby effect the overall explosion protection. EoL switch-off test 1 + 2 # EoL 1 – Asymmetric pulse test If an increased voltage drop is detected (as in the case of an old fluorescent lamp), the effected lamp power circuit is switched off. # EoL 2 – Asymmetric power test In this testing circuit, the increased power consumption loss of the used fluorescent lighting element is measured. The lamp power circuit is switched off before the limit value for power loss (< 10 W) is reached. The following applies to both of the test methods: If the old lamp is replaced with a new one after electronic ballast switch-off, then the ballast functions properly once again. All safety circuits function selectively: only the power circuit for the defective lighting element is deactivated. Electronic ballast 6042/9 Typ 2 x 18 W, 2 x 36 W oder 2 x 58 W Electronic ballasts are used for single-lamp or two-lamp applications Explosion protection EII 2G EEx de II C Certificates PTB 03 ATEX 2140 U Lamp start-up Cold start within 300ms Mains voltage AC: 220 V -10% … 240 V +10% 50/60 Hz DC: 198 V … 254 V Temperature range -20°C … +50°C Energy classification EEI = A2 Lamp wattage Rated voltage 2 x 18 W 2 x 36 W 2 x 58 W Rated current at 220 V/240 V 0,17 A/0,15 A 0,32 A/0,30 A 0,50 A/0,46 A Lamp power consumption 32 W 64 W 100 W System power rating 36 W 69 W 109 W Power factor cos ϕ 0,96 0,97 0,98 Service life Note: 55.000 hours at 50°C ambient temperature a) Switch-off of circuit 1 and 2 at the end of the service life (EoL) according to IEC 61347-2-3 b) With integrated DC switching relay, which means 1-lamp DC emergency lighting operation
