Expanded range of EMC filters for
Comp-AC drives
ABB Automation has expanded its range of EMC filters to give users of its Comp-AC low power AC drives increased flexibility in the way they address EMC issues of applications between 0.12kW and 37kW
ABB Automation has expanded its range of EMC filters to give users of its Comp-AC range of low power AC drives increased flexibility in the way they address the EMC issues of applications between 0.12kW and 37kW There are two types of Comp-AC EMC filter: regular (mounted on the top or bottom of the drive), and footprint (installed between the drive and the mounting surface)

Electrical equipment from ABB Automation is being installed as part of a £20m programme by East of Scotland Water (ESW) to upgrade water supplies to central Scotland.
ABB drive saves two days of set up time
A 37 kW variable speed drive with Direct Torque Control (DTC) from ABB Automation is being used to control the speed of a motor in a friction-welding machine that manufactures valves for car engines.
As the filters are add-ons the extra cost of built in filters is avoided in applications where the filters are not required.
The range of regular filters has been extended down to cover 400V applications between 2.2kW and 11kW.
The range conforms to IP 21 protection and no additional holes have to be drilled to fit the units.
The range of footprint filters has been extended to cover the entire Comp-AC power range from 0.12kW to 37kW and provide a suitable solution to applications where limited wall space is available.
Increasingly strict legislation means that EMC (Electromagnetic Compatibility) is becoming an increasingly important issue for machine builders, system integrators and OEMs.
ABB has opted to follow the requirements of the EU's EN61800-3 EMC Product Standard for power drive systems rather than the generic standards followed by some manufacturers.
The regulations define two types of installation environment.
For applications in the 'second environment' (premises not directly connected to a low-voltage supply network which supplies buildings used for domestic purposes) Comp-AC drives meet EMC requirements in their standard form and no additional filters are necessary.
For applications in the 'first environment' (domestic premises and premises directly connected to a low-voltage supply network which supplies buildings used for domestic purposes) the appropriate EMC filter has to be used.
ABB can also provide expert guidance and information about EMC issues.
For example they have produced a series of tables that calculate the maximum drive to motor cable lengths permitted and can provide help to OEMs looking to get their products CE marked.
