Citel DIN Rail Surge Protectors

LED Lighting Protection

LED street lighting is popular for its efficiency, energy savings, and long life. This enticing technology is sensitive to transient voltages from lightning or AC power switch operations. Due to its distributed and overexposed placement, LED lighting systems encounter generated surges that can damage LED components or reduce lighting effectiveness. Use surge protectors upstream of LED lighting systems for these reasons. CITEL offers surge protectors for luminaires, street lighting pole boxes, and street cabinets and LED lighting solutions for urban, architectural, and tunnel applications.

When considering surge protection for your networked devices, it is crucial to select the appropriate equipment for each task. There is more to surge protection than simply connecting a device; in fact, there are multiple forms of surge protection, each with various core components that perform the "dirty job" of dissipating surges away from your vital equipment. MOVs, SADs, and GDTs are the three most common core components; most surge protectors are constructed around one of these three and are characterized by the characteristics of that component. There are also multi-component, hybrid, and multi-stage variants available for improved coverage.

Metal Oxide Varistors

MOVs, or metal oxide varistors, are the most prevalent surge prevention technology. This is typically seen in the widely available surge protection strips designed to safeguard consumer devices plugged into outlets. MOVs are initially sturdy surge protection components, able to withstand severe surges, but they deteriorate over time. MOV-based products, despite being inexpensive and simple to use, have significant restrictions and are often not the ideal option for vital data and networked devices.

Silicone Avalanche Diodes

Silicone avalanche diodes, or SADs, are the most prevalent form of surge protection for data and networked devices. In contrast to MOVs, they do not raise the capacitance of the circuit, allowing data to flow freely along the network while still providing effective surge protection, which is necessary for any networked device to prevent packet loss and throughput concerns. SADs are highly fast-reacting components that provide quicker surge protection than MOVs, but they are less robust, needing a smaller surge to cause them to self-destruct and require replacement.

Gas Discharge Tubes

GDTs, or gas discharge tubes, are generally the most powerful surge prevention component, making them excellent for safeguarding externally mounted electronics that require lightning surge protection or other installations where significant surges are possible. Additionally, they are often relatively compact, enabling for easier installation on devices with limited space. However, as the slowest reacting surge prevention component, they are not appropriate for rapid, fast-traveling surges.

The most typical design for hybrid surge protectors combines a SAD with a GDT, allowing the faster response time of the SAD to compensate for the slower GDT's ability to absorb a considerably bigger surge and divert it away from the network and its devices. Many of these components are available in both modular and non-modular surge protectors, making it easier to tailor your solution to your system's precise requirements.

Consider the essential components of the surge protection you are installing when selecting surge protection for your essential equipment. Hybrid designs offer the best of all possible worlds but may be more expensive. Despite the fact that all of these components provide surge protection, it is necessary to ensure that they provide the type of protection your devices require to operate and that they are appropriately protected against power incidents.

CITEL has protected vital networks and equipment against overvoltages since 1937. Their surge protection products safeguard sensitive devices from lightning and switching events. They specialize in surge-protection devices for original equipment manufacturers, network operators, and end-users. Other crucial surge protection components they offer include gas discharge tubes, thermally shielded varistors, and high-energy varistor assemblies. All of their products are intended to be integrated into an installation to safeguard all electrical, electronic, and data-processing equipment from transient overvoltages.
