New EMI filters from Schaffner with low leakage current

EMC filters for 3-phase applications are key elements that contribute significantly to compliance with the EMC directive and improve the customer's system reliability and stability. The offering of the new FN 3287 and FN 3288 series has been extended with low leakage current versions. System designers now have the choice of an EMI filter with leakage currents from 12 to 0.1mA. This next generation product has optimised packaging which is based on the latest component and design technology.

By specifying appropriately sized EMC filters during the start of the design-in phase, the design of machines and installations can be optimised to meet the required EMC from the outset. In addition, considering EMI requirements at an early stage of system design saves resources, time and costs. These Schaffner EMI filters are based on a new design architecture resulting in a significant footprint reduction and allowing the inclusion of the connection terminals within the filter cubical.

With the new FN 3287 and FN 3288 product series, Schaffner can now provide very compact and very flexible options from 10 to 160A to accomplish standard- or high-demanding attenuation performance requirements as well as low-leakage current fulfilment.

The FN 3287 (480V AC) and FN 3288 (480V AC or 690V AC) series are available with 11 current ratings from 10 to 160A and special versions of low-leakage currents can enable dedicated systems with RCDs. The FN 3288 series includes also a suitable version for 480 VAC or 690V AC IT network applications.

All models are CE, UL and ENEC approved and RoHS compliant. For further information about the FN 3287 and FN 3288 series EMI filters, please visit www.schaffner.com.
