This intelligent high-frequency electronic dimming ballast utilizes the DALI or Touch and Dim push-button protocol for fluorescent lamps. It meets A1BAT requirements, thereby pre-empting upcoming legislation. With a special command you can retrieve the system’s mains power consumption, and with another you can find out which lamp wattage is connected. Combined with controls, additional energy savings can be achieved.

• · Extremely low stand-by losses, controlled cut-off for dim levels above 80%, hybrid control dimming (current control at 100% and power control at 1%) – combined with MASTER TL5 Eco the most energy-efficient solution
• · HF operation improves light quality and lamp lifetime.
• · Compliant with European and Asian norms and suitable for emergency lighting systems
• · HF-R Intelligent recognises what type of lamp (T5 HE, HO, ECO, TL-D, PL-L) is connected and drives it accordingly
• · Programmed start: flicker-free ignition 1.0 second and striation-free operation, no stroboscopic effects. Preheating the lamp electrodes enables the lamps to be switched on and off without reducing life
• · Smart power ensures constant light, independent of mains fluctuations and dimming from 1 to 100%
• · Stop circuit is activated within 5 seconds in the event of lamp failure (safety stop), and ballast resets automatically after lamp replacement
• · Programmable for intelligent functionalities via Philips MultiOne: Corridor mode, Emergency DC dim level, Burn-in time
