LED Lights SPDs
Surge Protectors for LED lighting system
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.
LSP offers a surge protectors designed to be installed at different points on the lighting network such as streetlights, the base of poles and street cabinets.
The MLPC is a compact solution surge protectors to be installed in small spaces. The device is available in spring terminal connection and wiring (input / output opposite).
In cases of extreme aggression, MLPC will be in a state of safe end of life: the indication of failure (disconnection) of the surge protector is performed by the extinction of an indicator and switching off the AC (extinction street luminaire) inform the user of the need for maintenance.
Surge protector for use in single-phase TT and TN systems
- Plate mounting, very compact
- Spring terminal connection
- Status indicator
- End of life AC Disconnection
