Schaffner’s new IEC inlet EMC filters offer small
form factor, cost effective performance attenuation.

Schaffner, the international leader in the field of electromagnetic compatibility, has extended its range of filtered IEC inlets in response to a strong demand for a wide mounting flange version coming from the Asian market as well as the need to have backward compatible products for older models nearing their end of life. The new larger mounting flange offers an increased conductive area for safety and optimum filter performance.

This enlargement of the FN9222 IEC Inlet filter series meets growing market demand and completes the FN9222 filter series. At the same time the opportunity has been taken to rationalise the whole of Schaffner’s IEC inlet filter range by integrating the functionality of the existing FN321 filter within the current FN 9233 series. The new FN 9222 and FN 9233 IEC Inlet filter families employ the same standardised housing and materials ensuring cost effective filter solutions for Schaffner’s customers.

The new FN 9222U features the new wide mounting flange, is rated up to 15A and has the usual options available such as an on board bleed resistor and a medical version. The FN 9222UZ filter also has the wide mounting flange version and includes a metal oxide varistor (MOV) for surge pulse protection.

The FN9233UF2 completes the extension to Schaffner’s filtered IEC connector range updates. It also features the wide mounting flange and in addition includes two X capacitors, one at line side and one at load side. The Y-capacitors are increased from 2.2nF to 3.3nF. This gives the FN 9233UF2 better high frequency attenuation performance.

The new high performance, small form-factor FN 9222 and FN 9233 products share many common features such as rated currents up to 15A, excellent attenuation performance, optional earth line choke, optional medical versions (B type), snap-in versions (S and S1 type) and hot inlet versions (HI type).

The FN 9233 and FN 9233E IEC inlet filter modules have been developed for systems or switching power supply units that require a high level of interference suppression. Compared with the standard FN 9222 filter family the new FN 9233 series offers higher symmetrical and asymmetrical attenuation performance. The FN 9222E and FN 9233E IEC inlet filters also include an earth line choke, for applications requiring the reduction of interference signals on the earth line.

Paul Dixon, Managing Director of Schaffner comments. ”Our FN 9222 and FN 9233 IEC filter connectors now offer the widest range and best value ever available from Schaffner. Integrating the IEC connector and EMC filter not only offers our customers a reduced component count, it also reduces cost and assists the system designer to gain EMC approvals. The new FN 9233 offers up to 6dB more attenuation than our existing FN 9222 in the same package size. These new IEC filtered connectors provide a safe, high quality mains connection and filter solution.”

The complete range of new FN 9222 and FN 9233 IEC mains inlet filters are available direct from Schaffner and a number of global distribution sources. Typical applications include electrical and electronic equipment, consumer goods, test and measurement equipment, rack mounted systems, electronic data processing and point of sale systems, office automation and Datacomms equipment.

Class A/B 3-phase+neutral sum, 4-wire filtering
“Safe Touch” Terminal Blocks
Compact Design

Schaffner Ltd, the market leader in EMC components and test systems, announces the introduction of a new filter to its very successful compact industrial FN3280H EMC filter range. Rated at 200A @ 50°C the new model and has been introduced to meet demands for higher power from machinery and power cabinet manufacturers.

The FN3280H filter range now has 9 models rated from 8 to 200A and all offer 3-ph+N sum filtering for potentially noisy machines connected to low-voltage electricity networks, which may also supply domestic or commercial users. In these environments Class A and occasionally even Class B EMC filtering is required. To simplify system design the filter currents of all models have been aligned to commonly available fuse protection values and outstanding low leakage currents of <1mA are attainable in 4-wire connection mode. 

The new FN3280H-200-40 offers outstanding filter performance in a very compact package and does not de-rate under full-load operating conditions. Connection is made via Schaffner’s proprietary “touch safe” terminal blocks that meet EN60204-1 to provide maximum safety for installers, inspectors and operators. 3-phase/4-wire filters are now a standard product and available off the shelf.

The FN3280H range of filters is ideal for machine tools with up to 12 driving axes with 10 to 10m of motor cable each likely to be operated in mixed domestic environments and will allow manufacturers to comply with Class A or even Class B filtering. FN3280H filters also improve the immunity and reliability of the entire system by also protecting the machine against incoming conducted interference from the operating environment. This additional protection ensures maximum productive up-time and lowers maintenance costs.

“We have introduced this new 200 amp filter in direct response to our customers’ needs.” comments Andy Kotas, Marketing Manager of Schaffner Ltd. “Machine tool and power cabinet manufacturers are always under pressure to provide more power, frequently in restricted spaces. Our very compact, safe, easy to use, high performance filters are an ideal solution”

Typical applications include, manufacturers of machinery, machine tools, and process automation equipment, energy conservation devices and regenerative motor drives, power cabinets, premium 3-phase + neutral power supplies and UPS and solar power technologies.

           Single-Phase High Performance EMC Filters
Simplifies Panel Building and Industrial Control Systems

Schaffner Ltd the market leader in EMC components and systems announce the introduction of the FN 2412 series of DIN Rail mounting EMC Filters. This new family of high performance single-phase filters are will fit industry standard TS 35 DIN rails and offer a simple to use, time saving, cost effective solution to conducted EMC suppression for panel builders and control cabinet manufacturers. The extensive range of current and voltage ranges available mean that even special applications can now be protected with an off the shelf solution.

A sophisticated mounting system provides a simple and time saving snap-in mounting of the filters onto TS 35 DIN rails. The innovative shaping of the DIN-rail mounting bracket as well as its material guarantee low-impedance connection to the HF ground ensuring an optimal (asymmetric) filter effect, which has previously only been available by using traditional bolt-down chassis mounting methods. The FN 2412 filters have been designed, electrically and mechanically, to meet the requirements of industrial equipment and control cabinets.

With models available off the shelf for rated currents from 8 to 45 A the correct FN 2412 EMC filter will typically ensure system conformity to Class A limits for Industrial and Residential environments. Owing to the high saturation resistance, this high attenuation performance is available even with very aggressive noise sources and under full load. Schaffner’s specially designed “Touch-Safe” connection terminals make accidental touching of live conductors impossible ensuring maximum safety when in use.
 
These new filters are designed for a maximum continuous operating voltage of 250 VAC and there is also a standard version FN 2412H available for higher operating voltages up to 520 VAC. All models are safety agency approved to UL, CSA and ENEC and are RoHS compliant.

Andrew Kotas, Marketing Manager of Schaffner Ltd. comments “these are our first Din Rail mounted EMC filters which we hope will provide our customers with even more convenience and flexibility when having to provide EMC suppression on their systems. While effective EMC protection is required to meet international noise emission standards it can also improve system reliability and reduce expensive downtime caused by external conducted interference damaging internal components”

The FN 2412 range of EMC filters are also available in chassis mounting form for applications where Din Rail mounting is not possible. Designated FN 2410 these noise suppression components are available for the same voltage ranges (250 VAC and 520 VAC) and for an extended current range up to 100 A.
