Electro Magnetic Interference (EMI) filtering is the process of reducing high levels of varying frequencies (or noise) that enter your devices. This noise affects the normal performance characteristics and the reliability of those electrical devices.
There are two types of filtering methods, Emission filtering and Immunity filtering.
Emission filtering involves connecting the EMI filter directly after a device that produces electrical noise, for example after an inverter motor. This filter will reduce the interference levels on the output side so that other devices down the line won’t be affected. This is also a good way of reducing conduction emission, ensuring additional interference is not put back onto the grid risking higher electricity charges.
Immunity filtering is simply protecting sensitive instruments from being disturbed by interference. In noisy environments where there are high levels of electromagnetic radiation, long power cords can absorb interference from the surroundings and send it straight into your devices. Immunity filtering involves fixing a filter very close to the input side of the device. This will purify the electrical supply so that no harmful high frequencies of EMI can enter the instrument. This protects the device making sure only correct frequency levels pass through. This type of filtering method has been used to protect equipment such as displays, that don’t always have high immunity to noisy environments.
The BL2020 EMI power filter has one of the most compact designs accompanied with multiply fitting options available. These include Faston, Screw, Wire and even Terminal input and output connectors. This means installation is quick and simple and with its compact design will take up minimal space. This interference Power Filter is also suitable for a huge range of applications such as control panels, motor drives, power supplies and medical devices.
The BL2020 is available in many different amp sizes as well as optional types. These optional types include: Type A – for Safety Critical applications (Low capacitance and low leakage current) and Type B – for Medical applications (No Y capacitance and very low leakage current). The Amp sizes go from as little as 1A all the way up to 60A.This allows electromagnetic interference to be reduced in whatever the circumstance.
The benefits to you from filtering out interference are increases in your electrical efficiency, reliability and performance, while at the same time, filtering provides reductions in disturbances, down time and maintenance costs over your whole process.
