EMI Filters for Construction & Infrastructure Industries | Custom EMI Solutions Available


In the construction of large commercial and office complexes, setting up the electrical infrastructure is a critical consideration. Office buildings, railway stations, hospitals, airports, hotels, etc require careful planning and deployment of electrical equipment with special focus on EMI/EMC.


Issues of power supply, power quality as well as lighting and air conditioning are the main areas of focus. Minimising power consumption and ensuring 24X7 operations with zero breakdown are important for these sites. There is a high density of electrical equipment in these campuses and therefore largely susceptible to EMI.

EMI filters can be a valuable add-on to these systems for lowering the EMI levels of the equipment without significantly impacting the cost, size, or function. EMI filters are designed and manufactured specifically for these applications to limit the noise generated to an acceptable safe level.

Many countries in the world have their own safety standards for EMI filters. So they should be selected based on what is approved by the safety standards of the countries to which the device will be exported.
