What is a smart CCR?
A constant current regulator that still regulates and protects the circuit — but also measures itself and reports, so engineers see problems early.
A smart CCR is a constant current regulator with added measurement and communication. It still holds the series circuit at the set current for each intensity step, with its own protection, but it also measures output current, voltage, load and temperature and reports them, with alarms and logs, to the ALCMS.
The data gives early warning, trends and remote diagnostics, so visits can be planned instead of reactive. But the CCR’s regulation and protection are not changed and must not depend on the network. An engineer confirms an alert and decides what to do, and the link needs cyber-security like any connected equipment. It supports the maintenance programme and does not replace it.
- Regulate. Hold constant current at the selected step, as any CCR does.
- Protect. Keep its own protection against open circuit, overcurrent and faults.
- Measure. Read output current, voltage, load, temperature and insulation where fitted.
- Report. Send status, alarms and logs to the ALCMS over a protected link.
- Advise. Show trends and early warnings, and allow remote diagnostics.
- Act. An engineer confirms and fixes; later readings show whether it worked.
Regulates and protects like any CCR, and also measures its output and condition and reports them to the ALCMS.
Regulates and protects the circuit with local indication and basic status signals, but little measurement or data logging.
Frequently Asked Questions
Q1What is a smart CCR in airfield ground lighting?
A constant current regulator with added measurement and communication. It still holds the series circuit at the set current for each brightness step, but it also records data such as output current, voltage, load and temperature and reports them to the control system.
Q2Does a smart CCR regulate differently from a conventional one?
No. Its core job is the same: keep the circuit current constant at the selected step, with its own protection against faults such as an open circuit or overcurrent. The smart part is the data and communication added around that job, not a change in how it regulates.
Q3What does a smart CCR report?
Typically the selected step, output current and voltage, load, alarms and faults, run time and temperature, and insulation or earth-leakage readings where the equipment includes them. The exact list depends on the model and its options.
Q4How does a smart CCR connect to the ALCMS?
Through a communication link such as serial, Ethernet or fibre, using the protocol the supplier and the control system support. The ALCMS can then show status and alarms, log the data and, where permitted, send commands such as intensity step changes.
Q5What are the risks and limits of a smart CCR?
Data is only as good as the sensors and their calibration, a network fault can hide the picture, and a connected device needs cyber-security such as access control and a protected network. Protection must not depend on the network, and site checks are still needed.
Q6Does a smart CCR replace maintenance?
No. It helps focus maintenance by giving early warning and remote diagnostics, but inspection, testing and maintenance still follow ICAO Annex 14, the national regulator and the aerodrome’s approved procedures. An engineer confirms an alert before acting on it.

Recognising an AGL system visually is the first step. The next step is knowing how to design, install, test, commission and maintain them correctly.
