Noise filters and surge protectors are both devices that ensure the stability and performance of electrical devices.
There are differences in their roles and functions.
Noise filter
Purpose : To reduce electrical noise and interference.
function :
-
Improves the quality of power supply by eliminating or reducing electrical interference signals.
-
Prevents electromagnetic interference (EMI).
-
Prevents signal distortion.
-
Protect sensitive electronic devices from electrical noise.
-
Because it has low surge resistance, it is used together with Class I and Class II surge protectors.
Applications : Used in medical devices, communication equipment, factory automation systems, etc.
Surge protector
Purpose : To protect electronic devices from power surges (sudden increases in voltage).
function :
-
Prevent damage to electronic devices caused by power surges.
-
Blocks voltage spikes caused by lightning or power supply fluctuations.
-
Protects electronic devices and circuits to extend their life.
-
Absorbs energy when a surge occurs and releases it safely.
-
The noise filter is a product corresponding to surge protection device T3 Class III.
Applications : Used in electronic devices and electrical systems in homes, commercial buildings, and industrial facilities.
