Three-Phase Line Filters help keep out EMI noise.
Press Release Summary:
Suited for 4-wire WYE applications with balanced and unbalanced 3-phase loads from 20-60 A, Corcom A Series provides common mode and differential mode suppression from 50 kHz to 30 MHz. Corcom ADT Series is available with common or differential mode coils for Delta applications from 63-200 A. For very noisy Delta applications, 6-50 A Series FCD attenuates conducted interference at low and high frequency ranges, protecting components from RF noise on AC power line.

Three Phase Line Filters Help Keep Out Noise
HARRISBURG, Pa. - Dec. 5, 2005 -Tyco Electronics' line of Corcom 3-phase power line filters continues to gain acceptance in the North American electronics market. 3-phase EMI noise suppression is an important part of electrical system design for a number of industrial applications. The heavy switching of inductive and capacitive loads in industrial electronics as well as the high energy often used in these applications is a breeding ground for EMI which can hamper microprocessors and many other sensitive electronic devices and components.
Among the scenarios where 3-phase EMI noise can result include large motors, motor drives and other high-power electronics including transformers and high-power induction circuitry.
Some of the common applications in this area include motor controls and motor control centers, welding equipment, CNC machinery, elevators, frequency converters and industrial ovens and furnaces. Further, high power commercial cooking and restaurant equipment are likely candidates for 3-phase power line filters.
The Corcom A Series 3-phase filter is designed for four wire WYE applications and provides filtering in each of the three lines plus filtering in the neutral and ground lines. They provide common mode and differential mode suppression from 50kHz up to 30MHz. A Series 3-phase filters are suitable for balanced and unbalanced 3-phase loads ranging from 20A up to 60A.
For Delta applications, Tyco Electronics has designed the Corcom ADT series 3-phase filter. The ADT series filter has very high insertion loss and is especially applicable for motor drive installations requiring compliance with European EMC directives. ADT filters are available for applications ranging from 63A up to 200A and are available with common or differential mode coils.
In very noisy Delta applications, the FCD series filter is available. FCD filters attenuate conducted interference at low and high frequency ranges and protect components like PLCs from RF noise on the AC power line. Often, the FCD filter is used in frequency inverter systems and variable speed motor drives. Current ratings for the FCD range from 6A up to 50A.
Tyco Electronics has several other Corcom 3-phase power line filters for other applications.
