The atg airports Micro 100+ CCR is a cutting-edge solution meticulously crafted for optimal performance for use with airfield ground lighting circuits. This device is equipped with a micro-controller seamlessly integrated with an analogue control and protection loop, overseeing an anti-parallel pair of thyristors for precise phase angle control.

The Micro 100+ (CCR) is a self-contained cabinet and is divided into four main compartments;


  1. Microcontroller and Display:
    • A PCB Sub-assembly utilizes a microcontroller for easy parameterization of CCR characteristics.
    • Monitored and alarm information is displayed, ensuring comprehensive control.
    • All electronic sub-assemblies are conveniently accessible from the front of the CCR cubicle.
  2. Analogue Electronic:
    • This compartment houses the main control PCB, featuring components like the feedback controller, error amplifier, thyristor triggering circuit, and lamp failure detection.
    • Easy accessibility from the front of the CCR cubicle ensures efficient maintenance.
  3. Power:
    • Located at the rear, this compartment hosts crucial power components for the CCR output current loop.
    • Components include the Thyristor Stack, Main Contactor, Main Transformer, Lightning Arrestor, Feedback Transformers, Fuses, Filters, and Cable Terminals.
    • Accessible from the rear, ensuring a streamlined approach to maintenance.
  4. Connection:
    • This compartment facilitates hassle-free connection to input terminals and grants access to fuses.
    • Conveniently located at the rear of the cubicle, eliminating the need to access the power compartment.
