Output Filters and Reactors

Output filters and reactors for motor protection and the improvement of system reliability, availability and functionality. Deployed at the output side of frequency inverters, these components ensure reliable operation by avoiding expensive downtimes of installations, manufacturing plants, machinery and a vast array of other industrial and domestic motor drive applications due to premature motor damage. An appropriate output solution will even allow the deployment of unshielded motor cables, the use of multiple motors in parallel on the same drive or the retrofit of modern drives in existing installations with old motors and unshielded cabling.

Three-Phase + Neutral Line Filters

Three-phase and neutral line EMC/EMI filters are a compact solution for the interference suppression on the mains input of cabinets and control units of equipment, ranging from industrial applications like machine tools to sensitive medical installations. These typically involve separate and often insufficiently filtered frequency inverters and SMPS, causing current imbalance and significant interference problems. As individual elements they may be interference-suppressed already. The conjunction of several switching components in the same cabinet and a non-EMC conscious cabling will rise the demand for an additional EMC/EMI filter on the mains input of the whole installation. Many times this is the only way to get the CE mark for the cabinet in accordance with the EMC directive.

IEC Inlet Filters / Power Entry Modules


DC Filters

DC filters from Schaffner are specifically optimized for applications with DC supply like e.g. photovoltaic inverters.

Three-Phase Filters

EMC/EMI three-phase filter solutions for industrial applications like motor drives and machine tools. Furthermore, these types of EMC/EMI filters are also suitable for mainframe computer systems, large uninterruptible power supplies, medical equipment, wind turbine power stations and a vast array of other three-phase power electronics.

Feedthrough Components

Feedthrough filters and capacitors offer an EMI suppression up into the GHz range for high-tech applications such as IT, telecom, server and networking equipment.
