Constant Current Regulator (CCR) & Airfield Lighting Control & Monitoring System / ALCMS (distributed/integrated by Vardhman Airport Solutions) vs PAPI & Airfield Photometric Calibration System — mobile (Unika / PAC, distributed by Vardhman Airport Solutions)
Spec comparison for two products on Aviation Souk. Both compete in Runway Lighting & Airfield Electrical.
An integrated microprocessor-controlled series-circuit power supply and airport-wide lighting supervisory system — the CCR and ALCMS working together to maintain constant lamp current across all five brightness steps while giving ATC complete monitoring and switching authority over every airfield lighting circuit.
A paired photometric calibration solution — vehicle-mounted mobile runway/taxiway light measurement and tripod-based PAPI angle calibration — enabling airfield maintenance teams to verify ICAO and FAA photometric compliance on the airfield without the airport closing.
