LED street lighting is now widely used for its efficiency, its energy cost savings and its life expectancy. Nevertheless this attractive technology has an important weakness: its sensitivity to transient voltages created by lightning or by power switch operations on AC network.
Due to its scattered and over-exposed location, LED lighting system will face induced surges which will create failure of its power supply, damage LED components or loss of the lighting efficiency. For these reasons, the use of relevant surge protectors located upstream the LED lighting systems is highly recommended.
CITEL offers a full range of surge protectors designed to be installed at different points on the lighting network such as streetlights, the base of poles and street cabinets.
CITEL offers solutions adapted to every type of outdoor LED lighting systems : urban, architectural, tunnels etc…
CITEL proposes a complete range of AC surge protectors specifically designed for the protection of LED lighting systems in the lantern or connection boxes.

MLP range is a complete range of AC surge protectors specifically designed by CITEL for the protection of LED lighting systems at the lantern. Many versions have been proposed to meet the various existing configurations : surge protection devices are available in different isolation classes (Class I, Class II) and connection type (wire or screw terminal) and equipped with additional protection for data line (RS485, DALI, 0-10V) to provide a complete solution for LED systems with control lines.
In cases of extreme aggression, the surge protector will be in a state of retirement security: according to the different versions available, an indication of the failure of the surge protector is performed by the extinction of an indicator, a AC power disconnection and / or through a remote signalisation.
