All Surge Protection & Filters
Industrial surge protection and filters are protective devices used to safeguard industrial electrical and electronic equipment from transient voltage surges, electrical noise, and power disturbances. Industrial surge protectors are typically used in automation, manufacturing, utilities, process control and other industries to protect sensitive electrical equipment from damage or disruption caused by lightning, switching surges and electrical disturbances. Proper application of industrial surge protection and filtering are required to minimize equipment downtime, increase life expectancy, and ensure continuous operation of industrial equipment.
Industrial surge protectors work by diverting or clamping surge voltages to a safe level before the transient energy is allowed to pass into the circuitry of the equipment to be protected. Typically applied at the control panel, distribution board, I/O communication lines and automation panel, they protect the likes of Programmable Logic Control (PLC), Human Machine Interface (HMI), power supplies, sensors and communication networks from overvoltage.
Power line filters, or line filters, are used to filter out electromagnetic interference (EMI) and radio frequency interference (RFI) signals on power lines and signal lines. They "clean up" the incoming electrical and signal noise and act to suppress conducted interference so as to ensure signal integrity for proper operation of automation and control equipment.
FAQs
What is surge protection used for in industrial systems?
Surge protection is used to protect industrial electrical and electronic equipment from transient voltage spikes caused by lightning, switching events, or power disturbances that can damage components or cause system failure.
What do industrial power filters do?
Industrial power filters reduce electrical noise such as EMI and RFI on power and signal lines, helping improve signal integrity and prevent interference-related faults in control and automation systems.
Where should surge protection devices be installed?
Surge protection devices are commonly installed at service entrances, power distribution panels, control panels, and near sensitive equipment such as PLCs, HMIs, power supplies, and communication devices.
Why are surge protection and filters important in automation systems?
They are important because automation systems rely on sensitive electronics that can be damaged or disrupted by voltage spikes and electrical noise. Surge protection and filters help ensure reliable operation and reduce unplanned downtime.
How do surge protection and filters improve system reliability?
By limiting overvoltage events and suppressing electrical noise, surge protection and filters prevent equipment damage, reduce errors, and support long-term stable operation of industrial electrical systems.
