The family of Smart Force DC-AC EL inverters from Endicott Research Group (ERG) Inc. provides a wide range of standard and custom solutions for display and device designers who need to power electroluminescent (EL) backlit LCDs. Vacuum encapsulated for maximum reliability, ERG’s Smart Force inverters actually prolong the useful life of the EL lamps they power because they automatically adjust operating voltage and frequency as the lamp ages and changes.
