Lenze 13125078 FS21002-11-07 EMC Mains Filter
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 13125078, identified by model code FS21002-11-07, is a single-phase industrial EMC mains filter within the Lenze Mains Accessories product family. Engineered to suppress high-frequency electrical disturbances caused by power electronics, this unit attenuates conducted noise generated during frequency inverter operation before it can feed back into the plant power network. Operating across a nominal supply voltage of 230 V AC within an effective range of 100 V AC to 250 V AC at 50/60 Hz, the filter is rated for a continuous operating current of 2.0 A, providing crucial electromagnetic protection for sensitive electronic hardware in industrial panels.
Connecting the unit into a machine control cabinet is performed inline directly between the single-phase AC mains supply and the input terminals of the frequency inverter. Because the filter is a passive component, putting a replacement spare into service does not require software configuration, parameter adjustments, firmware updates, or programming tools. Commissioning a replacement unit simply involves confirming correct physical wiring and verifying that the attached drive's input current does not exceed the filter's 2.0 A maximum rating. ABC Industrial Parts provides expert support and spare part availability to help technicians select and integrate the correct mains accessories into existing drive setups.
As a passive noise suppression filter, the unit functions without internal electronic status indicators or display modules. Routine field troubleshooting involves confirming that line voltage remains within the supported 100 V AC to 250 V AC window, checking terminal connection integrity, and ensuring total continuous load current remains below 2.0 A. If electrical breakdown or thermal overload causes internal failure, the filter cannot be repaired in the field. Swapping out a failed filter with a fully tested replacement from ABC Industrial Parts is the standard process to quickly restore full EMC directive compliance and protect surrounding equipment.

Replacement and Spare Part Considerations
When replacing a Lenze 13125078 EMC filter, exact electrical matching is critical to maintain network compliance and safeguard upstream power quality. System integrators must confirm that the replacement filter carries the FS21002-11-07 model designation and is deployed on single-phase 100 V AC to 250 V AC power lines operating at 50 Hz or 60 Hz.
Because this mains filter is a passive hardware accessory, replacing an existing unit requires no parameter transfers, memory card migrations, or software synchronization. Technicians should verify that the continuous input current of the connected single-phase frequency inverter does not exceed the filter's 2.0 A limit, preventing premature thermal degradation and maintaining effective high-frequency noise attenuation.
