PRELIMINAR Y DATASHEET
Application Specific Discretes 2 -CHIPS SET FOR FLUORESCENT LAMP STARTER A.S.D.TM
DESCRIPTION The EFS Kit is a 2 chips set used with 4 additional passive components as direct replacement of the Glow switch Starter. The ASDTM (Application Specific Discretes) includes a bi-directional Power Switch and a Power Supply for the driver. The driver provides a program to ensure a fully optimised fluorescent lamp ignition. FEATURES VERY WIDE POWER RANGE: linear lamp ignition from 18 to 125W VERY WIDE TEMPERATURE RANGE: tube ignition from - 40 to 85 °C 8 STRIKING PULSE CAPABILITY: for very cold environment or aging lamp SELECTABLE PRE-HEAT TIME: 1.5 s or 2.5 s IGNITION at 350mA, 1350V STARTER SHUTDOWN WITH FAILED LAMP BENEFITS Very low component count: 2 chips + 4 passive components Universal Core for any multi power multi temperature range starter application Serial tube lamp connection capability (note 1) Compatible with EMI Capacitor to meet EMI standards Extended life time of the fluorescent lamp due to smooth and single shot ignition Very Cold and Lower power application coverage with selectable and accurate pre heat time Unaffected by Mains Power micro-interruptions Reduced maintenance thanks to failed lamp automatic safety shut down Extended life time of the starter t hat survives to the tube lamp failure Inherent high reliability of the electronic power elements
