Philips electronic dimmable HF-R ballasts for compact fluorescent lamps

High frequency electronic adjustable ballast for compact fluorescent lamps type PL-T/C, PL-L dimming = another step towards energy savings HF-Regulator II for PL-T/C. Compact high frequency electronic ballasts for dimming control using analogue protocol (1-10V) for PL-T, PL-C, PL-R and PL-L fluorescent lamps.

Advantages
- Lamp output can be dimmed from 1 to 100% via
analogue input control (in accordance with industry standard
1-10V)
- In accordance with European and Asian standards, suitable for
emergency lighting systems
- High-frequency operation improves light quality and lamp life

- In combination with drivers, further energy savings can be achieved

Features
- Programmed activation: flicker-free illumination in less than 0.5
seconds, streak-free operation and no strobe effects.
Preheating of the light source electrodes allows switching
light sources on and off without shortening their lifetime
- Smart power supply ensures constant light regardless of fluctuations in
mains voltage
- Up to
60% reduction in energy consumption can be achieved with automatic lighting control systems.
- The switch-off circuit is activated within 5 seconds in the event of a failure of the light
source (safety switch-off); after the light
source has been replaced, the ballast automatically resets
