Why Use an EMC Filter?

Variable speed drives generate electromagnetic emissions that can interfere with nearby control equipment, communication networks and sensitive electronics. The SD1-RFC3-7 reduces conducted emissions from compatible SD1 drives, helping installations comply with EMC requirements and improving system stability.

Designed specifically for the SD1 range, the filter provides a straightforward solution for achieving industrial EMC compliance without complex external filtering arrangements. It is particularly suitable for smaller three-phase SD1 drives where optional external C3 filtering is required.

Typical Applications

• Three-phase SD1 inverter drive installations.
• Industrial automation control panels.
• OEM machinery and equipment.
• Conveyor systems.
• Pump and fan control applications.
• Packaging machinery.
• Manufacturing equipment.
• Industrial systems requiring EMC compliance.
