Schurter 5121 Appliance Inlet Filter

March 30, 2023
Schurter Logo1.jpg

IEC C14 Appliance Inlet Filter
• Ultra compact IEC C14 inlet filter
• Optimal high frequency mains input filtering
• Fully closed steel housing
• V-Lock cord retaining

Schurter launches a new very compact filter series with the 5121 appliance inlet filter. An IEC C14 inlet is surrounded by a closed metal housing and thus effectively shields the mains input. The new filter series is available as a standard or medical technology version for a rated current up to 10 A / 15 A with wire connections.

The mains input is often a critical opening in the housing. Interference via the power cables and interference radiated through the opening gets into, or out of the housing. The new 5121 appliance inlet filter series offers a very compact solution to prevent interference.

Applications
The new filter family is especially suitable for applications with very small installation depths that require high-frequency filtering of the mains input at the same time. The 5121 appliance inlet filter reliably shields high-frequency interference conducted through cables or radiated thanks to a completely closed metal shield and capacitors. Interference in the lower frequency range can be reliably attenuated with additional capacitors and chokes on the PCB. Especially the interferences in the low frequency range < 10 MHz are mainly conducted through the cables, which means that the filter components do not necessarily have to be located at the mains input and can simply be placed on the printed circuit board. Schurter offers a wide range of current-compensated and linear chokes for this purpose. Typical applications are medical, laboratory, audio- and video equipment and industrial systems.

Multiple Mounting Versions
The new filter series is available in three mounting versions: Screw mounting from the front side with plastic flange, screw mounting from the front or rear side with metal flange and snap-in mounting from the front side. All variants guarantee optimal electrical contact of the mounting panel thanks to the wide metal flange. The closed filter housing acts as optimal shielding of the mains input.

Approvals
The 5121 series is certified for currents up to 10 A/250 VAC according to IEC and 15 A according to UL/CSA at 125/250 VAC. It has ENEC, CQC and cURus approvals.

Schurter FMAB NEO PE-Choke Filter

March 30, 2023
Schurter Logo1.jpg

Single Phase Block Filter
• Filter with ground choke
• Excellent symmetrical attenuation
• Fully closed steel housing
• Optional wire leads

Schurter is expanding the successful FMAB NEO single-phase filter family with new variants. The filter is now available with an additional ground line choke to suppress high-frequency interference on the earth conductor. The new filter series is available in standard and medical versions for a rated current range of 1 A to 20 A with quick connect terminals.

Standard filters only filter the pole and neutral conductors, the earth line stays untouched. This can be a problem with the occurrence of high-frequency earth conductor currents, because in this case even the best filter can’t do any improvements. The new filter versions with integrated earth conductor chokes
offer a simple solution.

Ground Choke
New variants of the FMAB NEO single-phase filters are equipped with a ground line choke. In addition to the current-compensated choke on the pole and neutral conductor, the mains filters have a second choke on the earth line. The ground line choke is located between the filter input and output. The filters
therefore have two earth connections at the input and output, whereby the earth connection at the mains input is insulated from the housing. This ensures that possible high-frequency interference currents on the earth conductor cannot bypass the filter via the housing. Especially medical filters (without Ycapacitors) benefit from an improved asymmetrical attenuation in the higher frequency range due to the earth conductor choke.

Applications
Filters with earth line chokes are used in most applications with critical high-frequency earth line currents. High-frequency earth conductor currents are generated by any type of fast energy conversion such as switching power supplies, frequency converters or motor drives. Earth loops can occur in devices that are connected to other devices with shielded cables. The high-frequency interference current occurring on this earth loop is effectively attenuated with a ground choke. Typical applications are medical and laboratory equipment, audio and video as well as industrial systems.

Approvals
The single-stage FMAB NEO filter family has a particularly compact design combined with high performance. It is suitable for applications in the temperature range from -40 °C to +100 °C and has ENEC and cURus approvals.

The new filters meet the requirements of machine safety according to IEC 60204-1. They are suitable for 3-phase or 3-phase-with-neutral conductor applications at rated currents from 16 to 230 A.

The FMAC NEO and FMAD NEO single-stage block filters have a particularly compact design with a small footprint and high performance at the same time. They are suitable for industrial or energy applications such as EV fast charging stations or battery storage.

IEC 60204-1: Machine Safety
Any machine or equipment that is to be brought onto the market in the EU and associated countries must bear a CE marking issued by the manufacturer himself. With this marking, the manufacturer guarantees that his product complies to all applicable legal and technical requirements. Minimum standards with regard to safety and occupational health requirements are defined in Europe by the Machinery Directive 2006/42/EC and the Low Voltage Directive 2014/35/EU.

The details for implementation are defined in separate specifications, known as harmonizing standards. One of these harmonizing standards is IEC 60204-1, which applies to electrical, electronic and programmable electronic equipment as well as to groups of networked machines, including control cabinet construction.

New Filter Variants
The new filter versions meet the requirements of this standard IEC 60204-1. The filters have a short discharge time of the capacitors, so that they have a touchable residual voltage of <60 V in 1 or max. 2 seconds after disconnecting the voltage. Further, the insulation value between phases and ground is at least 1 MΩ thanks to larger resistors. The filters are designed for currents from 16 to 230 A at an ambient temperature of 50 °C.

All family members have ENEC and cURus approvals and are recommended for applications up to 520 VAC. The standard variants are designed for industrial applications with leakage currents <13 mA. Special variants with leakage currents <3 mA are available for particularly leakage-critical applications.

Schurter RTS Thermal Fuse - Improved Protection of Power Semiconductors

November 12, 2021

Schurter Logo1.jpg

RTS Tripping Temperature > 175°C

Improved Protection of Power Semiconductors
• Protects power semiconductors from thermal runaway
• SMD reflow solderable up to 260 °C
• Tested for usage up to 60 V
• Integrated current measuring sensor (shunt)

Schurter RTS thermal fuse, successfully launched in 2018, gets a new variant with a tripping temperature of >175°C. The RTS is a particularly compact overtemperature protection device for power semiconductors in SMD technology for highest demands.

RTS stands for Reflowable Thermal Switch. It was developed to protect highly integrated power semiconductors from overheating. Prior to mechanical activation, the new thermal fuse can be soldered on conventional reflow soldering machines with profiles up to 260 °C.

Protection Against Thermal Runaway
Thermal runaway refers to the overheating of a power semiconductor due to a self-reinforcing, heat-producing process. One of the reasons is the trend towards increasing power density and miniaturization of electronic circuits. The RTS protects these power semiconductors against thermal runaway. In such an event, the thermal fuse acts as a fail-safe device and reliably interrupts the circuit from as early as 175 °C and thus addresses the operating temperatures of common power semiconductors even better.

Minimal Footprint
The new overtemperature protection device comes in the same minimal dimensions and maximum breaking capacity despite its additional shunt functionality. On its small 6.6 x 8.8 mm footprint the RTS can handle operating currents of up to 130 A and rated voltages of up to 60 VDC.

Integrated Current Measuring Sensor (Shunt)
The shunt version has an integrated resistance with particularly low temperature dependence. This resistance, known as a shunt, enables precise current measurement and enables an additional – non-thermal – circuit protection, e.g. via a controller.

Schurter FMBD EP 3-Phase Mains Filter

August 3, 2021

Schurter Logo1.jpg

FMBD EP 3-Phase Mains Filter
• Compact design with minimal footprint
• Double-stage filter with high attenuation
• Variants for high voltage applications
• Wide temperature range

Schurter introduces the FMBD EP double-stage flagship filter family for 3 phases with neutral line systems. Thanks to its particularly compact dimensions and high performance, the new filter series is ideally suited for the tight space conditions in today's machine and industrial plant construction. Versions with high nominal voltages make a wide field of applications possible.

Space is a scarce commodity in control cabinets for industrial applications in the 3-phase range. Schurter has addressed this problem with another completely new filter design, which is much more compact than previous generations. The new, almost cuboidal design makes optimum use of the space in the housing. Thanks to a double-stage filter and the use of the highest quality components (generously dimensioned film capacitors, chokes with highly permeable cores), the new development shines with exceptional broadband filter attenuation.

Suitable for High EMC Emissions
The double-stage filter family is therefore also appropriate for applications with particularly high EMC emissions, as is frequently encountered in industry. Typical applications include machines and systems for automatic production, motor drives and industrial plant machinery. These powerful filters are also the first choice for modern frequency inverters for motor control.

Mounting
The FMBD EP series features screw terminals for absolutely safe wiring. Thanks to the metal flange, an excellent earth connection is ensured when screwed to the chassis.

Wide Temperature and Voltage Range
The standard types 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 have both ENEC and cURus approval for applications up to 520 VAC and ENEC and UR approval for applications up to 760 VAC.

Leakage Current
The standard versions are designed for industrial applications with leakage currents of <9.4 mA. Special variants with leakage currents of <2.5 mA are available for critical applications.

The completely redesigned FMBD EP models are the ideal replacement for all types of SCHURTER FMBD and FMBD NEO filters. They offer at least identical performance with significantly reduced dimensions and weight.
