CCR Constant Current Regulator (IWT.570.CCR) 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.
Runway Lighting & Airfield Electrical
CCR Constant Current Regulator (IWT.570.CCR)
by Inewatt
SCR-technology constant current regulator supplying airfield series lighting circuits at rated intensity steps, with LED-circuit compatibility and a 1–25 kVA range.
Runway Lighting & Airfield Electrical
PAPI & Airfield Photometric Calibration System — mobile (Unika / PAC, distributed by Vardhman Airport Solutions)
by Vardhman Airport Solutions
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.
