25th May 2023

Surge protectors are crucial devices that protect electrical equipment from sudden voltage spikes or surges. This buying guide provides an overview of surge protectors, including their definitions, types, functions, applications, and a call-to-action to explore the range of surge protectors offered by TOSUNlux, a reputable manufacturer in the industry.

What is a Surge Protector

A surge protector, also called a surge arrester or surge suppressor, is an instrument designed to safeguard electronic devices and appliances from voltage spikes. It works by diverting excess electrical energy to the ground and ensuring that connected equipment receives a steady and safe supply of power.

Types of Surge Protectors

  • Power Strip Surge Protectors

These surge protectors combine multiple electrical outlets with surge protection capabilities. They are typically used in homes and offices to protect an assortment of devices simultaneously.

  • Wall-Mounted Surge Protectors

These surge protectors are designed to be directly mounted on the wall, providing surge protection for specific areas or individual outlets. They are ideal for areas with limited space or where a discreet installation is preferred.

  • Whole-House Surge Protectors

These are lodged at the electrical board or the primary service access to provide protection for the entire electrical system of a facility. They offer comprehensive protection against external surges, such as lightning strikes or power grid disturbances.

Functions of Surge Protectors

  • Voltage Regulation

Surge protectors help regulate the voltage supplied to connected devices, maintaining a stable and safe level of power. They prevent voltage spikes from damaging sensitive electronics.

  • Surge Suppression

The primary function of surge protectors is to suppress or divert excessive voltage spikes away from connected equipment. By redirecting the excess energy to the ground, they prevent damage to devices caused by power surges.

  • Noise Filtering

Some surge protectors include noise filtering capabilities, reducing electromagnetic interference (EMI) and radio frequency interference (RFI). This function ensures a cleaner power supply and improves the performance of connected devices.

  • Cable Line Protection

Some surge protectors come with in-built protection for cable lines, such as coaxial cables used for cable TV, satellite, or internet connections. This additional safeguard ensures that your audiovisual and communication equipment is protected from voltage spikes that can travel through these lines.

  • Fire Protection

Certain surge protectors incorporate fire-resistant materials and safety features to minimize the risk of electrical fires. These surge protectors can help contain any potential fire caused by electrical faults or surges, providing an extra layer of protection for your home or office.

Applications of Surge Protectors

  • Home Electronics

Surge protectors are normally used to protect TVs, computers, gaming consoles, audio systems, and other sensitive electronics in residential settings.

  • Office Equipment

Surge protectors are essential in office environments to safeguard computers, printers, servers, and other office equipment from power surges.

  • Industrial Machinery

Surge protectors are employed in industrial settings to protect critical machinery, control systems, and production equipment from voltage spikes that could cause downtime or damage.
