Subject: EU Council EMC Directive and the Products of Amerace

Conclusion
For the reasons given in the following, the airfield lighting products of Amerace are exempt from the requirements of the EMC Directive.

EMC Directive
EU “Council Directive of 3 May 1989 on the approximation of the laws of the Member States relating to electromagnetic compatibility” regulates the electromagnetic compatibility of some kinds of electrical equipment.

Scope of EMC
Article 2, Section 1 states:
“This directive applies to apparatus liable to cause electromagnetic disturbance or the performance of which is liable to be affected by such disturbance”.

Products
Listed in detail in the Amerace product catalog or on our web site, and generally consisting of Isolating transformers encapsulated in thermoplastic rubber, or various kinds of specialized connectors, either molded on cables, or in kit form for field assembly.

Application
All products are used in airfield lighting for runway, taxiway or approach lighting. Most airfield lighting circuits are series, fed by a constant current regulator (CCR). Click for a typical electrical layout. The transformers are needed to ensure that the circuit continues to operate when a bulb burns out, and to keep the high voltages underground for safety considerations.

Discussion
All of these devices are inherently immune to electromagnetic disturbance.

All of these devices are passive , and do not cause electromagnetic disturbance.

Disposition
Since these devices are immune and passive, there is no requirement for an EC mark under the EMC Directive.
