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.

Among its range of constant current regulators, GRP has designed a compact version of its sinewave CCR.

This efficient design will allow to spare room in crowded substations, by pilling up 2 or 3 CCRs in one column and still benefit the high performances of state of the art IGBT based CCRs.

The CCRs are also maintenance friendly, thanks to removable side panels providing easy access to internal parts.

The stackable CCR design allows installation on shelves as well.

On the field, technicians hold a rugged tablet so that they can access the system at any given time and share information as soon as they can, using on the spot intervention input.

The system integrated tools are also communicating, in order to limit hand writing and related errors.

Automatic Cut-Out

The SCSA system is designed to allow airport maintenance technicians to work safely on AGL power circuits.

The system will cut-out the load from the CCR, short circuit and ground the airfield lighting circuit in order to decommission the AGL installation and guarantee safe maintenance operation, it will also avoid any unexpected re-commissioning that could lead to incident.
