DCR Constant Current Regulator for Pearl LED Airfield Lighting

DCR Constant Current Regulator for Pearl LED Airfield Lighting

This DCR constant current regulator is the power and control unit for Pearl LED airfield lighting circuits. It serves operators of regional airports and remote strips who need a stable series circuit with intensity control. The unit guards the installation against open circuit and overcurrent, and holds 1.4 A whatever the number of lights connected.

Benefits

• Controlled intensity: three steps, so the lighting follows the visibility on the day.
• Protected installation: built-in protection against open circuit and overcurrent.
• Four configurations: one or two independent 450 W outputs, with or without ARCAL radio control.
• Fast cabling: lights connect in series with pre-made FAA L-823 cables and quick connectors.
• Wide climate window: a rated range from -40 degrees C to +50 degrees C.

Applications and installation

The DCR regulator is built for airport lighting and works with Pearl lights fed at a constant 1.4 A. Install it in a protected technical space, since the enclosure is rated at minimum IP40 and must stay dry. The ARCAL version adds radio control, which helps on strips with no permanent ground staff. Each 450 W output feeds a separate series circuit, so you can command two runway segments independently. Designed and manufactured in Europe.

Frequently asked questions

How many circuits can one DCR constant current regulator feed? The single version has one 450 W output; the dual version has two independent 450 W outputs.

What does ARCAL mean? It is the radio control version: the lighting intensity is commanded remotely, without ground assistance.

Can I mount it outdoors? The rating is minimum IP40, so install it inside a cabinet or a technical room protected from water.
