Very low component count: 2 chips + 7 passive components Meet EN55015 standards WITHOUT EMI capacitor Extended life time of the fluorescent lamp due to smooth and single shot ignition High inherent reliability and extended life time of the starter
PENTAWATT HV EFS21-TL5
DESCRIPTION The EFS Kit is a 2 chips set used with 7 additional passive components, for Glow switch Starter. The ASD™ (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 linear fluorescent lamp ignition.
