If you’re experiencing interference with your telephones, flickering computer monitors, reliability issues with data networks, instrumentation errors, or misbehaving electronics you are most likely experiencing EMI or RFI in your electrical environment.
Electromagnetic interference (EMI) and radio frequency interference (RFI) are unwanted electrical noise that can interfere with digital, analogue and communication equipment and processes. The disturbance may interrupt, obstruct, degrade, or limit the effective performance of the circuit. In the case of a data path, these effects can range from an increase in error rate to a total loss of the data. Both man-made and natural sources can generate changing electrical currents and voltages that cause EMI.
There are common mode and differential mode components to EMI noise. Common mode EMI noise is transmitted on multiple conductors at the same time and in the same direction on all conductors from source to receiver. Differential mode noise is induced on a conductor and travels in the opposite direction as it does on the ground conductor. This is like a complete circuit with a separate and return path for the EMI.
The most common solution to remove unwanted electrical noise from your process is to use EMI powerline filters. These are passive electronic devices used to suppress conducted interference present on power or signal lines. They can be used to suppress the interference generated by the device itself, as well as to suppress the interference generated by other equipment.
CD Automation have a comprehensive range of single and three phase EMI power filters that suits a wide range of domestic, commercial and industrial applications, many available in stock for next day UK delivery.
Our single phase, bulk mount filters start at currents as low as 1A, maximum voltage supply of 250Vac and available in multiple sizes including 3A, 6A, 10A, 12A, 16A, 20A & 30A from UK stock holdings. Seven different filter designs including single, dual and multiple stages provide excellent noise suppression across a wide range of applications including:
- building & process automation
- consumer goods
- datacom & office equipment
- drives & controls
- elevators & cranes
- general machinery
- power & energy applications
Many other current, voltage sizes and connection types available depending on your application needs. All units are CE / UL / CSA / NEMKO / ROHS and ENEC approved and come with 5-year warranty.
Our extended range also includes IEC inlet filters, Harmonic filters and cable exit filters.
