Surge protection devices for network technology and server rooms

Surge protection devices in the electronics industry are specialized components designed to protect devices from sudden voltage surges caused by lightning strikes or transients in the power grid. They usually consist of protective elements such as varistors, gas arresters or transient voltage attenuators, which dissipate the excess voltage and thus prevent it from damaging sensitive electronics. In industrial applications, surge protective devices are often used in machine control systems, data networks and communication systems. They work by reducing the voltage to a safe level in the event of overvoltage, thereby extending the service life of the connected devices and ensuring their operation.

Surge protection devices for electrical control systems

Surge protection devices are used in numerous areas where sensitive electronic devices need to be protected from the dangers of lightning strikes or electrical surges. In industry, these devices are often used to protect production machines and control systems. Surge protection devices are particularly indispensable in automated production processes, as they protect against sudden current peaks that can be caused by lightning strikes or switching operations in the power grid.

Surge protection devices are also essential in the IT and telecommunications industry to protect server rooms and network technologies from damage. Okaya and Bourns devices, which offer reliable protection against transients, are primarily used here. Surge protection devices can also be found in modern households, where they protect sensitive devices such as computers, televisions and household appliances from surges. These solutions not only prevent equipment failure, but also help to extend the life of your electronics.

Further information on surge protection devices

In this section you will find answers to the most frequently asked questions about surge protection devices and their application. Find out how these devices work, why they are essential for your electronics and how to choose the right model for your specific requirements. Our experts have compiled the most important information to help you make the right decision for protecting your devices and systems.

What are surge protection devices and how do they work?

Surge protection devices are specially developed components that protect electronic devices from dangerous overvoltages. These overvoltages are often caused by lightning strikes, switching operations in the power grid or faults in electrical systems. The devices work by dissipating the excess volta...

Why are surge protection devices essential for industry?

Surge protection devices are crucial in industry to protect production machines and control systems from sudden power surges. These devices can be triggered by lightning strikes or by the switching of large machines. Surge protective devices prevent these power surges from damaging machinery or cau...

What are the advantages of surge protection devices for data networks?

Data networks are particularly susceptible to damage from electrical surges caused by lightning strikes or transients. Surge protection devices protect servers, routers and other network devices from these dangers. Without this protection, data loss and system failures can result. Our surge protect...

How do you choose the right surge protection device?

Choosing the right surge protection device depends on various factors, such as the type of electrical systems, the level of protection required and the specific requirements of the applications. It is important to choose a device that takes into account both the voltage and the current of the devic...

How do you install surge protection devices and how often should they be serviced?

Surge protection devices can usually be quickly integrated into existing systems. They can be used either as a module, mounted on the PCB or as an SMD variant. They are often installed directly at the points where the power supply flows into the devices. Once installed, surge protection devices are...
