Benefits of Three-Phase EMI Filters

Different types of electrical networks have various power demands. Smaller items — such as consumer electronics and home appliances like microwaves — have little power demands and only need Single Phase power. But High Power applications — like industrial machinery and test equipment — require more power to function. Three-Phase power is often used to distribute power in these large-scale applications.

Three-Phase EMI Filters offer more effective noise suppression in high-power applications than their Single-Phase counterparts. Because electrical noise can impede the functionality of many electronic and electrical devices, Three-Phase Filters can keep your high power products running smoothly and help you maintain compliance with federal EMI regulations.

Applications of Three-Phase Filters

A wide array of industries use Three-Phase EMI filters in their daily operations. Equipment manufacturers specifically benefit from using three-phase filters in a variety of industrial machinery. Some of the many uses of these filters include:

  • Three-Phase inverters and frequency converters
  • Industrial machine tools
  • Industrial Power Supplies
  • Fixed Computer Systems
  • MRIs and X-Ray Equipment
  • Foodservice Equipment
  • Elevators and Escalators
  • Commercial Vending
  • Gaming Machines
  • Frequency Converters
  • Test Equipment
