Noise filters and surge protectors play an important role in cleaning and protecting electrical signals.

• Noise Filter : Prevents electromagnetic interference (EMI) or high-frequency noise from penetrating electrical circuits. This helps maintain stable signal quality in audio equipment, computers, medical devices, etc.

• Surge protector : Protects your devices by preventing sudden high voltage (surge) surges. Lightning, power fluctuations, and other reasons can cause high voltages momentarily, and surge protectors block them, preventing damage to electronic devices.

Ultimately, both devices play a vital role in maintaining the stability of electrical signals and extending the life of electronic products.

The technical standards for noise filters and surge protectors vary depending on their respective roles and application methods.

• Noise Filter : It reduces electromagnetic interference (EMI) and high-frequency noise and follows international standards such as IEC 60364-5-53. This provides a basis for selecting and installing appropriate equipment in electrical installations of buildings.

• Surge Protective Device (SPD) : It protects equipment from sudden overvoltage (surge) and follows standards such as IEC 61643-12 and KSC IEC 61643-12. SPD is classified into Type I, II, and III, and each has different test criteria and application methods.

These technical standards play a vital role in increasing the safety of electrical installations and extending the life of equipment.
