FN3287/FN3288 Series Book-Style EMC Filters

Schaffner's FN3287 and FN3288 series are designed for motor drives, power drive systems, and many other power converter applications. These innovative filters are optimized to best serve the requirements of machine tools and machinery equipment. Small is not just beautiful, but also very powerful.

Along with appropriately sized EMC filters the design of machines and installations can be optimized to meet the EMC standards in case the EMC filters are being considered already during the start of the design-in phase.

The filters are based on an updated design structure resulting in a significant footprint reduction and allowing integration of the connection terminals within the filter cubical.

With the FN3287 and FN3288 product series, Schaffner can provide very compact and widely usable solutions from 10 A to 160 A to accomplish standard or high-attenuation performance requirements as well as low-leakage current fulfillment.

The FN3287 and FN3288 series are available with 11 current ratings from 10 A to 160 A. Both series are available for 480 V_AC and the FN3288 series is also for 690 V_AC and IT network applications.

All models are CE, UL, and ENEC approved and RoHS compliant.

Features

• State-of-the-art EMI attenuation based on an innovative filter topology, helping to ensure compliance with Class C2 or C1 limits
• The slim book-style shape allows a convenient and space-saving installation next to inverters, converters, or motor drives
• Designed for the most diverse applications worldwide, including machinery and machine tools
• FN3288 HV filters up to 160 A are applicable for 690 V_AC distribution networks
• FN3288 IT and FN3288 HVIT filters up to 160 A meet the special requirements for IT distribution networks
• Low-leakage current filter versions help to fulfill tough requirements (i.e. 0.1 mA) in respect of leakage current limitation
