LED technology and lighting has taken over the market because of their efficiency, versatility, energy savings and longer life. But why is surge protection needed, particularly in outdoor applications? While they have countless benefits, the technology also has a number of drawbacks, including higher cost of implementation, more complex internal electronics and they are much more sensitive to overvoltages than traditional light sources.
To help extend the life of an outdoor LED luminaire, the use of overvoltage surge protection systems is a cost effective investment to ensure the ROI of LED projects.
Often times people associate SPDs with interior machinery, but with outdoor LED lighting, it’s important to protect your equipment, or your cost savings might go out the window. So what is a surge protection device (SPD)? A SPD connects upstream of the drive, complements the intrinsic immunity of the luminaire, creating a more robust protection against lightning and overvoltages. SPDs protect equipment by discharging the overvoltage to earth, therefore limiting the voltage reaching the equipment.
The three-stage SPD solution from Mersen
- Lighting Panel (SPD+POP series)
- Pole/Fusebox (STM SLIM series)
- Luminaire (STLB series)
Surge Protection in the Lighting Panel
This is the first stage of protection. A two-in-one combined (POP + SPD), it protects against permanent or temporary overvoltages (POP) is the perfect complement to the typical first stage protection, a type 2 SPD in the lighting panel.
Surge Protection in the Pole/Fusebox
Mersen’s STM SLIM is the new range of LED arresters which provides a solution for installation in fuse boxes (located in the mast of the luminaire) with a DIN rail. It’s perfect for retrofitting.
Surge Protection in the LED Luminaires
These feature STLB Surge-Trap, the best in-line surge protection for LED lighting applications. A single device is suitable for single, split or three-phase applications; can be installed in series or parallel with the luminaire; features leakage current free technology and visual end-of-life indication. The fastening flange allows the SPD to be installed upright or flat, depending on the space constraints of the luminaire.
It is certified and suitable for worldwide installations.
Mersen’s Surge-Trap three stage LED solution is ideal in a wide range of outdoor lighting applications, including: street lighting, industrial lighting, public lighting, parking garages/surface lots, stadiums, tunnels and much more.
