Micro 200 Constant Current Regulator

The Micro 200 is ATG Airports' advanced constant current regulator (CCR) for airports transitioning to or operating fully LED airfield ground lighting systems. Unlike conventional thyristor regulators that generate distorted waveforms, the Micro 200 uses pulse-width modulation of an IGBT H-bridge to produce a clean sinusoidal output at near-unity power factor across all eight brilliancy steps, substantially reducing harmonic loading on the airport's electrical supply and improving the longevity of series-circuit isolating transformers.

Available in power ratings from 2.5 kW to 15 kW, the unit fits within the same cubicle footprint as earlier ATG designs, allowing upgrade projects to re-use existing switchroom infrastructure. Its microcontroller-driven display presents engineers with a comprehensive diagnostic dashboard — output current, brilliancy step, maximum output percentage, alarm descriptions, failed lamp counts, operational hours, insulation resistance readings, and power quality metrics — without requiring a connected laptop.

For GCC airports upgrading ageing CCR populations alongside runway or taxiway re-lighting programmes, the Micro 200 represents a single-vendor solution that eliminates the compatibility risk of pairing a third-party regulator with ATG LED fixtures. The unit accepts external brilliancy control via hardwired input or fieldbus protocols, integrating into modern airfield management systems.

Compliance with FAA AC 150/5345-10F, ICAO Manual Part 5, CAA CAP 168, and IEC 61822 means it satisfies the regulatory requirements of the great majority of civil aviation authorities worldwide.
