STARLIGHT-KIT
A.S.D.
2-CHIPS SET FOR FLUORESCENT LAMP STARTER
FEATURES
n VERY WIDE TEMPERATURE RANGE:
tube ignition from - 30 to + 85 °C
n SINGLE SHOT IGNITION FROM -30 to 0°C :
350mA, 1350V striking pulse
n VERY WIDE POWER RANGE:
Fluorescent tube lamp ignition from 18 to 70W
n EFS2B driver compatible with 50/60Hz
operation
n SELECTABLE PREHEAT TIME:
EFS2A driver: 1.5s or 2.56s (50Hz)
EFS2B driver: 0.74s or 1.24s (50Hz)
EFS2B driver: 0.62s or 1.03s (60Hz)
n 8 STRIKING PULSES CAPABILITY:
for very cold environment or ageing lamp
n STARTER SHUTDOWN WITH FAILED LAMP
BENEFITS
n Very low component count: 2 chips + 7 passive
components
n Meet EN55015 standards WITHOUT EMI
capacitor
n Extended life time of the fluorescent lamp due to
smooth and single shot ignition
n High inherent reliability and extended life time
of the starter
