Lenze ESMD5524TMF SMD Series 3-Phase Mains Filter
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze ESMD5524TMF is a 3-phase EMI/RFI mains filter belonging to the Lenze SMD Series. Designed to suppress high-frequency electromagnetic interference generated on the main power line, this noise filter operates with a continuous rated current of 14.2 A across a nominal supply voltage of 400 V AC to 480 V AC, with an allowable operating voltage range of 320 V AC to 528 V AC. Engineered specifically for use with 5.5 kW Lenze SMD series frequency inverters, the unit attenuates harmonic noise and backfed interference before it can disrupt surrounding electronic components, digital controllers, and sensors sharing the same power distribution system. Built with an IP20 ingress protection rating, it is designed for safe installation inside standard industrial control enclosures.
Connecting directly to the incoming 3-phase line supply ahead of the inverter, the ESMD5524TMF provides physical power line filtration without requiring software tools, firmware alignment, or parameter adjustments. Because the filter is a hardware-based passive component, commissioning a replacement unit involves ensuring proper mechanical installation within the control cabinet and correct wiring of the 3-phase input and output power terminals. The layout allows integration beside or beneath matching Lenze SMD drive frame sizes to optimize cabinet footprint and streamline panel wiring. When replacing an existing unit in established machinery, ABC Industrial Parts can assist in sourcing verified replacement components to keep legacy systems fully operational.
Because the ESMD5524TMF is a passive filtering component, it does not feature onboard status LEDs, digital diagnostics, or internal software fault codes. Operational checks focus on verifying 3-phase line voltages within the allowable 320 V AC to 528 V AC operating window, confirming secure terminal torque on power connections, and ensuring adequate physical clearance inside the IP20 cabinet enclosure. Severe line surges, phase anomalies, or internal hardware breakdown require complete unit replacement, as internal filter subassemblies are not field-serviceable. In such cases, securing a tested exchange or spare filter from ABC Industrial Parts offers a direct path to restoring proper EMC protection and returning equipment to production.

Replacement and Spare Part Considerations
Replacing a Lenze ESMD5524TMF mains filter requires verifying that the replacement unit shares identical electrical ratings to ensure continuous electromagnetic compatibility. Key specifications to match include the 14.2 A continuous rated current, the 3-phase 400/480 V AC nominal supply voltage (320 V AC to 528 V AC operating range), and compatibility with 5.5 kW Lenze SMD series variable frequency drives. Sourcing an exact matched spare is essential for maintaining noise suppression standards in existing control panels.
Since the ESMD5524TMF contains no microprocessors, parameter memory, or fieldbus firmware, swapping a unit requires no configuration transfers, backup restorations, or software setup. Maintenance personnel must ensure power is fully isolated before installation and reconnect input and output 3-phase power wiring according to panel schematics. Checking line-side connections and protective grounding continuity during installation ensures reliable attenuation of high-frequency interference across the automated system.
Frequently Asked Questions
Which drive models are compatible with the Lenze ESMD5524TMF mains filter?
The ESMD5524TMF mains filter is designed specifically for 5.5 kW Lenze SMD series frequency inverters operating on 3-phase 400/480 V AC power supplies.
What are the key electrical specifications of the ESMD5524TMF?
The filter features a continuous rated current of 14.2 A, a nominal voltage rating of 400 V AC to 480 V AC across 3 phases, and an operating voltage range of 320 V AC to 528 V AC.
Is software programming or parameter transfer needed when installing a replacement filter?
No. The ESMD5524TMF is a passive hardware filtering component, so replacement requires no software programming, parameter transfers, or firmware configuration.
