AGL technology has been evolving a lot in the past 15 years. LED light fixtures are now common products found on taxiways and runway, regulation has extended the use of signs, loads are more and more non-linear, green airport is now a reality thus power consumption is an issue, and further evolution is on its way. In order to match that challenge and provide a solution to its airport customers that will allow compatibility with existing installation and prepare the next generation of AGL series circuits, GRP has a developed a new range of state of the art sinewave CCRs. Based on IGBT technology to achieve current control, an efficient algorithm supported by the latest ARM Cortex-M CPU generation is providing an almost perfect sinewave whatever the load conditions as well as a fast response time to provide perfect operation as per ICAO and EASA requirements. An efficient design and easy access to internal parts will keep maintenance operation smooth and friendly.
