EMC filters for a reliable power supply
EMC filters limit high-frequency interference voltages and currents generated by equipment during normal operation and occurring under fault conditions. Using our EMC filters, you ensure smooth operation in environments subject to interference.More information
- Nominal load current
- Nominal voltage
- SFP2: Effective protection against high-frequency interferences and transient overvoltages, ensured by surge protection circuits acting on the input and output side of the filter
- User-friendly handling with easy assembly and installation, either with Push-in or screw connection technology
- FIL: Improved filter effect and EMC-optimized installation with additional PE terminals for separate connection to the local equipotential bonding system
- Space-saving and cost-effective thanks to DIN rail mounting
- Reliable and safe system operation with a reduction of conducted, high-frequency interferences
EMC filter fields of application
Frequency converters, switching power supplies, and lighting system drivers are often sources of interference in power grids. Some of the EMC interference is mitigated directly at the sources of interference by special filter circuits. However, the remaining interference can propagate and amplify via the supply and control lines. This can have unpredictable effects on controllers, power supplies, sensors, and actuators. Our filters limit the interference directly in front of the potentially susceptible equipment or the sensitive end devices.
EMC filters for universal use
Conventional filters only protect against high-frequency interferences, but not against overvoltage pulses. For effective protection, additional surge protection components are needed. SFP2 filters provide effective protection against surges and high-frequency interference as they feature a surge protection circuit that protects both the input and output side of the filter.
Simple and flexible installation
Thanks to the simple DIN rail mounting and the variable connection technology, using the filters in the control cabinet is child's play. Choose between the fast Push-in connection technology or proven screw connections for connecting the interference suppression filters.
The connection of the interference suppression filters to the local protective bonding is realized by additional PE terminal points. This improves the filter effect for high-frequency interferences between the active conductors and the ground potential. This way, an EMC-optimized installation and an improved protective effect is also achieved for EMC filters in plastic housings.
