Overvoltage protection

Q: What is the purpose of surge protection and how does it work?

Overvoltage protection is used to protect electronic devices from voltage peaks caused by external influences such as lightning strikes or sudden fluctuations in the power grid. These peaks can damage sensitive components or significantly shorten the service life of devices. Surge protection devices, such as TVS-Diodes or MOVs (Metal Oxide Varistors), dissipate excess energy and thus protect against damage. They are installed in a wide range of electronic devices, from household appliances to industrial machinery, preventing breakdowns and costly repairs. As a distributor of high-quality surge protection solutions, ROTIMA offers customized products for every application to ensure maximum safety.

Q: What types of surge protection devices are there?

There are different types of surge protection solutions, including TVS diodes, MOVs (Metal Oxide Varistors), Gas Discharge Tubes (GDT) and TISP® thyristor protection devices. Each of these technologies has specific applications and characteristics. TVS-Diodes are particularly fast to respond to voltage spikes and are often used in sensitive electronic components. MOVs are cost-effective and are well suited for household appliances. GDTs and TISP® protection devices offer a more robust solution for industrial applications where higher voltage peaks may occur. ROTIMA offers a wide range of these devices to optimize Overvoltage protection in different areas.

Q: Why is surge protection particularly important in industry?

In industry, surges are often a threat to expensive machines and production systems. A surge protection protects against the effects of sudden voltage peaks caused by lightning strikes or switching operations in the power grid. Without this protection, machines can fail, leading to expensive repairs and production downtime. Surge protection solutions such as MOVs, TISP® protection devices and GDTs are specifically designed for industrial applications to minimize such risks and maximize uptime. ROTIMA provides powerful and reliable protection solutions tailored to the requirements of industrial applications.

Q: How do you choose the right surge protection for electronic devices?

Choosing the right surge protection depends on various factors, including the type of device, its sensitivity and the potential overvoltages it is exposed to. For sensitive electronic devices such as computers or telecommunications equipment, TVS diodes are ideal as they respond immediately to voltage spikes. For robust applications in household appliances or networks, MOVs are a cost-effective solution. In industry, TISP® protection devices or GDTs are often used, as they provide reliable protection even in the event of extremely high overvoltages. ROTIMA can help you find the optimum surge protection for your specific requirements.

Q: How can surge protection be integrated into the installation of electrical systems?

When installing electrical systems, surge protection should ideally be taken into account as early as the planning phase. Surge protection devices such as TVS diodes, MOVs or GDTs are either integrated directly into the circuit or built into the power supply as separate modules. They can be installed on circuit boards as well as in socket strips or mains connection systems to protect all connected devices. Centralized protection systems are often installed in critical areas such as industry or large office facilities. ROTIMA offers customized solutions for the integration of surge protection devices that ensure long-term safety for your electronic systems.

Surge protection for network technology and server rooms

Surge protection devices in the electronics industry use various technologies to protect sensitive components from sudden voltage spikes. One common solution is TVS (Transient Voltage Suppression) diodes, which react immediately to overvoltages and dissipate the excess energy. These diodes can quickly reduce the voltage to a safe level, protecting the electronics from damage.

Another technology is Metal Oxide Varistors (MOVs), which also serve to absorb voltage peaks and relieve the protective components. In addition, TISP® thyristor protection devices and gas discharge tubes (GDT) offer an effective way of absorbing high overvoltages. These solutions are used in particular in industrial applications and in network technologies where high reliability is required.

Surge protection for the telecommunications infrastructure

Surge protection solutions are used in many areas of electronics and electrical engineering. In household appliances such as washing machines and refrigerators, TVS diodes protect against the potential damage caused by sudden voltage peaks, which can be caused by lightning strikes or faults in the power grid, for example. In industry, surge protection devices such as MOVs and TISP® thyristor protection devices are used to protect machines and production facilities from the effects of surges and maximize their uptime.

In the field of IT infrastructure, particularly servers and networks, surge protection solutions are used to protect sensitive data and equipment. Gas discharge tubes (GDT) and ChipGuard® ESD suppressors are used in telecommunication systems to protect expensive and complex equipment from damage and minimize downtime. These protection technologies ensure the reliable operation and long life of electronics in a wide range of applications.

What is the purpose of surge protection and how does it work?

Overvoltage protection is used to protect electronic devices from voltage peaks caused by external influences such as lightning strikes or sudden fluctuations in the power grid. These peaks can damage sensitive components or significantly shorten the service life of devices. Surge protection device...

What types of surge protection devices are there?

There are different types of surge protection solutions, including TVS diodes, MOVs (Metal Oxide Varistors), Gas Discharge Tubes (GDT) and TISP® thyristor protection devices. Each of these technologies has specific applications and characteristics. TVS-Diodes are particularly fast to respond to vol...

Why is surge protection particularly important in industry?

In industry, surges are often a threat to expensive machines and production systems. A surge protection protects against the effects of sudden voltage peaks caused by lightning strikes or switching operations in the power grid. Without this protection, machines can fail, leading to expensive repair...

How do you choose the right surge protection for electronic devices?

Choosing the right surge protection depends on various factors, including the type of device, its sensitivity and the potential overvoltages it is exposed to. For sensitive electronic devices such as computers or telecommunications equipment, TVS diodes are ideal as they respond immediately to volt...

How can surge protection be integrated into the installation of electrical systems?

When installing electrical systems, surge protection should ideally be taken into account as early as the planning phase. Surge protection devices such as TVS diodes, MOVs or GDTs are either integrated directly into the circuit or built into the power supply as separate modules. They can be install...
