Power Line Filters
A power line filter is a type of passive component that creates an electronic filter to deliver appropriate frequency characteristics to electrical circuits. Power line filters connect the electronic device with an external line to reduce conducted frequencies like radio frequencies (RFI) or electromagnetic interference (EMI) between the equipment and the connecting power line. This prevents any degradation in the circuit's performance.
RS offers an extensive range of high-quality power line filters from leading brands including Schaffner, Roxburgh EMC, Murata, Schurter and of course RS PRO. These power line filters come with various specifications to suit different needs, such as maximum current voltage, maximum voltage rating, mounting type, phase, and operating frequency, that are critical when sourcing for the right power line filters for your requirements.
What Are Power Line Filters Used For?
Power line filters are useful in emission reduction in switched-mode power supplies or machinery producing steam, smoke or carbon dioxide. These filters are also necessary to decrease levels of electromagnetic interference (EMI) which may cause undesired behaviour in radio transmission equipment and nuclear operations.
Types of Power Line Filters
Power line filters can be used in single-phase, three-phase or DC (direct current) power applications, depending on the equipment in question. Electric and electronic devices like switched-mode power supplies, motor controllers, induction cooking and food service equipment make use of single-phase filters. Three-phase filters are common in frequency converters, motor drives, and machine tools. DC filters are typically found in cell phones, flat-screen TVs and electric or hybrid vehicles.
What is The Difference Between EMI and RFI?
Electromagnetic Interference (EMI) filters refers to unwanted electromagnetic emissions that disrupt electronic devices or systems, often caused by sources like motors or power lines. Radio Frequency Interference (RFI) filters are a subset of EMI, specifically referring to interference within the radio frequency spectrum, commonly caused by wireless communication devices like radios or Wi-Fi routers.
Do You Need a Power Filter?
If your electronic devices are experiencing interference or erratic behaviour, it might be worth exploring the potential benefits of an EMI or RFI power filter. These filters can effectively mitigate issues stemming from electromagnetic or radio frequency interference from the power line, ensuring consistent performance and reliability for your devices.
How Long Do Power Filters Last?
The lifespan of EMI and RFI power line filters varies depending on factors such as usage, environmental conditions, and quality of the filter. Generally, they can last anywhere from 5 to 10 years or more with proper maintenance and care.
Industrial Applications of Power Line Filters
Power line filters are indispensable in various industrial applications where stable power supply is critical. They are essential power line filters in minimising electromagnetic interference (EMI) and power line filters for radio frequency interference (RFI), ensuring the smooth operation of machinery and sensitive equipment. Industries such as manufacturing, automotive, telecommunications, medical, data centres, and oil and gas rely on power line filters to maintain uninterrupted operations and protect equipment from electrical disturbances. For example, they are used in manufacturing plants to safeguard CNC machines from electrical noise and in telecommunications infrastructure to ensure clear communication signals.
