HFR149TL5II is an Electronic Regulating Ballast with flat lightweight high-frequency using 1 to 10V protocol for TL5 fluorescent lamps. The lamp power can be dimmed from 1 to 100% via the analogue control input, compliant with European and Asian norms and suitable for emergency lighting systems, HF operation improves light quality, lamp lifetime and combined with controls, additional energy savings can be achieved. It offers programmed start flicker-free ignition <0.5 seconds and striation-free operation, no stroboscopic effects. It features preheating the lamp electrodes enables the lamps to be switched ON and OFF without reducing life. it also features smart power ensures constant light, independent of mains fluctuations, up to 60% reduction in energy consumption by using automatic lighting control systems and stop circuit is activated within 5 seconds in the event of lamp failure and ballast resets automatically after lamp replacement.
