RESISTRON
LF-xx480 GB
Operating
Instructions
To comply with EMC directives – corresponding to EN 50081-1 and EN 50082-2 – RESISTRON and CIRUS control loops must be operated with interference suppression filters.
The use of a suitable line filter is part of the ! standards conformity and a prerequisite of
the CE mark.
These filters damp the reaction of the phase-angle control on the line and protect the controller against system disturbances.
ROPEX line filters are specially optimized for use in RESISTRON and CIRUS control loops. Providing they are installed and wired correctly, they guarantee compliance with the EMC limit values.
Please do not hesitate to contact us if you require design support for applications that are susceptible to extreme loads.
