Schurter Logo1.jpg

* Compact design
* Single-stage filter with high EMI attenuation
* Reduced weight
* Low leakage current versions available

Schurter launches its single-stage filter family FMAC NEO. Especially compact with high performance, the new filter series is ideally suited for use in today’s more portable industrial machines, designed to occupy less floor space in manufacturing plants. A wide temperature range extends its capabilities for use in many critical applications.

Three-phase control cabinets, in particular, can have space constraints. SCHURTER addresses this problem with a completely new filter design, which is much more compact than older generations. The new, almost cubed, design makes optimum use of available space in the cabinet housing. Designed with the highest quality components, the filter attenuation remains very high relative to its more compact dimensions.

The new filter family is also suitable for use in devices subjected to high EMC loads such as energy converters or motor drives. Typical applications include converters for photovoltaics, battery storage or charging stations for electric vehicles. These new high-performance type filters are also the better choice for modern day frequency inverters used for motor control.

The FMAC NEO filter series has screw terminals for safe and reliable wire terminations. A full metal flange guarantees a good earth ground connection upon screw mounting to the chassis. The standard versions can be used over a wide temperature range from -40 °C to 100 °C. The filters are designed for currents from 16 A to 230 A at an ambient temperature of 50 °C. They are ENEC and cURus approved and recommended for applications up to 520 VAC. The standard versions are designed for industrial applications with leakage currents <13 mA. Special versions for leakage-critical applications of <3 mA are also available.

The completely redesigned models of the FMAC NEO family are the ideal replacement for all types of Schurter legacy FMAC filters. The FMAC NEO offers the same high performance with significantly smaller dimensions and weight.

Schaffner 225_31.jpg

Schaffner, the international leader in the field of electromagnetic compatibility and power quality, introduces a new series of RFI filters with IEC Inlet C14 or C20.

The dual-stage high-performance FN 9255 filter series are an addition to the market proven FN 92XX filter families and have been developed for high frequency applications, above 30 MHz. The FN 9255 is the first power inlet designed by Schaffner to operate up to 300 MHz.

The only difference from a standard Schaffner IEC inlet is a slightly increased length, which means the FN 9222, FN 9233, FN 9244 and recently introduced FN 9255 all fit in the same cut out, allowing designers exchange inlet filters if the system requires higher performance than one of the basic models.

The new series offers a high number of variants of approximately 100 different filter types. Included in the range are versions designed for medical applications, one with and one without an earth line choke.

Another new feature of the series is a rear mount version, which includes a press-in nut to allow a reliable assembly without adding complexity to the system chassis.

The very wide variant diversity and comprehensive attenuation properties means the FN 9255 series offers an filtered power inlet solution for a wide range of applications including the latest household appliances, audio, video and also medical devices.

The filters have full international safety approvals (UL 60939-3, IEC 60939-3 and CQC), are CE marked and are compatible with the RoHS II (2015/863) directive.

Schurter Logo1.jpg

* Very compact design
* Various mounting options
* Variants with ground choke
* V-Lock cord retention
* Fuseholder meets latest IEC standard#

Schurter extends its successful power entry module series DD12 with new variants for screw and snap mounting. New versions are also available with additional ground choke for suppressing high-frequency interference on the ground conductor. The DD12 with fuse holder, switch and filter offers remarkable functionality in a very compact housing.

The DD12 filter series combines an IEC C14 appliance plug with a 1- or 2-pole fuse holder, a 1- or 2-pole switch and a high-quality mains filter. The particularly wide metal flange (horizontal or vertical) make contact with the housing surface over a large area and thus enables an optimum filter and shielding effect.

Ground Choke
The DD12 series is now available with a ground choke. In addition to the current-compensated choke on the pole and neutral conductor, the line filters have a second choke on the earth conductor. The ground choke is located between the device plug and the filter output. Placing the filter directly at the mains input ensures that possible high-frequency interference currents on the earth conductor cannot bypass the filter via the housing. The versions with medical filters (no Y capacitors) especially benefit from improved asymmetrical attenuation in the higher frequency range due to the earth line choke.

Applications
The DD12 series is available with standard or medical filter. It is suitable for use in devices that require a particularly high immunity to interference. These include IT or telecom systems according to IEC 90650-1 and medical devices according to IEC 60601-1.

The series meets the new fuseholder requirements outlined in IEC 60127-6 for enhanced fire safety and is also suitable for use in home appliances according to IEC 60335-1. It is compatible with V-Lock retaining cordsets.  The DD12 series is certified for currents up to 10 A/250 VAC according to IEC standard and 8 A according to UL/CSA standard at 125/250 VAC. It is ENEC and cURus approved.

Schurter – Two Are Better Than One

Schurter Logo1.jpg

More and more devices on the power grid must function smoothly without interfering with each other. Not so easy, since switching power supplies and highly clocked integrated circuits are used in almost all electronic devices. EMC filters can help here. Where necessary in multi-stage design.

In practice, it is quite possible that the attenuation is not yet sufficient despite the use of a filter. In such cases, several filter stages optimized for the specific interference signals are then connected in series. Which in interaction significantly improve attenuation in both differential and common-mode interference. Usually you get very good results with a doublestage filter. However, triple-stage filters are also conceivable, feasible and available.

Schurter – Protection Against Thermal Runaway

Schurter Logo1.jpg

A thermal runaway is an increasing threat to electronic devices where more and more power is packed in ever smaller spaces; it is a threat that is poorly dealt with using traditional means.

The causes of a thermal runaway are varied and often random in nature. However, the ever-higher power density in electronic wiring and the trend towards miniaturization are without a doubt of particular importance.

More and more functions are packed in compact modules, which then also have a correspondingly high power consumption. Even slightly excessive currents in power electronics with only a little power loss lead to elevated temperatures of approximately 200 °C. The possible consequences: damage or disconnection of surrounding components, damage to the printed circuit board structure or, in the worst case, the triggering of a fire.

Schurter Type DD14 Power Entry Module with Double-Stage Filter

Schurter Logo1.jpg

* Ultra-compact design
* Suitable for very high EMI disturbances
* Various mounting options
* V-Lock cord retaining option
* Fuseholder meets latest IEC standard

Today’s electronic equipment is designed to deliver high performance in a compact size. Often this causes problems affecting the equipment itself or other nearby devices due to the inherent electro-magnetic interferences being generated in and between the different systems. To meet these EMC challenges, high performance power entry modules must also keep pace, and such is the case with the new DD14 series from SCHURTER. The DD14 series packs remarkable functionality into a new generation of compact power entry modules.

The new DD14 combines an IEC C14 appliance inlet with 2-pole switch and 2-pole fuseholder. EMC performance is further enhanced with a depth-saving 2-stage filter. Shielding is optimized by screwing the metal casing of the filter to the panel, using its horizontal or vertical flange. A snap-in filter version eliminates the flange, consuming even less panel space.

The DD14 integrates the EMC filter directly in line with the power input. The two-stage filter design suppresses interference voltages more effectively over a much broader frequency spectrum than single-stage filters, thereby having a positive effect on electro-magnetic compatibility. Standard and low-leakage medical filter options are available for use in commercial or facilities ICT equipment according to IEC 60950 and medical equipment according to IEC 60601-1. The series meets the new fuseholder requirements outlined in IEC 60127-6 for enhanced fire safety and is also suitable for use in home appliances according to IEC 60335-1. It is compatible with V-Lock retaining cordsets.

The DD14 is rated for current levels up to 10 A / 250 VAC according to IEC and 8 A 125/250 VAC according to UL / CSA. It is ENEC and cURus approved.

Schurter RTS – Reflowable Thermal Switch

Schurter Logo1.jpg

• Prevents power semiconductors from thermal runaway
• Supports up to 60 VDC applications
• Reflow solderable at 260 °C
• Customer-specific version with shunt or overcurrent fuse
• Smallest dimensions

Schurter introduces its new RTS. The RTS is a particularly compact overtemperature protection device using advanced SMD technology. It is suited for the highest demands of protection in power semiconductors.

RTS stands for “Reflowable Thermal Switch”. It was developed to protect highly integrated power semiconductors like MOSFETs, ICs, IGBTs, Triacs, SCRs, etc. from overheating. Before mechanical activation, the RTS can be mounted using conventional reflow soldering techniques with temperature profiles up to 260 °C.

Mechanical Activation
After having the RTS reflow soldered on a PCB, mechanical activation arms the RTS for tripping at 210 °C. This activation can be done manually or by fully automated means. In contrast to electrical activation, the RTS activation status is clearly and immediately visible to the installer. Furthermore, the third additional contact required for electrical activation is thereby eliminated.

Compact Dimensions, High Load Capacity
The new type of overtemperature protection shines with the smallest dimensions and highest load capacity. Operating currents up to 100 A at rated voltages of up to 60 VDC can be handled by the RTS, which is just 6.6 x 8.8 mm in size. Customer-specific variants are available with an integrated shunt or an additional overcurrent fuse. These further integrated functions are resulting in less space consumed on the printed circuit board. The Reflowable Thermal Switch meets the high reliability requirements of AEC-Q200 and MIL-STD.

Protection Against Thermal Runaway
Thermal runaway refers to the overheating of a power semiconductor due to a self-reinforcing, heat-producing process. The reasons for this are the ever increasing power density and the trend towards miniaturization of electronic circuits.

RTS protects power semiconductors not through a logic circuit but rather through basic laws of physics. In case of a thermal runaway, the RTS reliably interrupts the circuit precisely at the well-defined temperature.

Technical Data
• Rated Voltage 60 VDC
• Tripping temperature 210 °C
• Operating current up to 100 A
