> FMBC LL: Low leakage current 3-phase filter
SCHURTER expands its successful range of FMBC NEO 3-phase filters with a low leakage current series for applications where no high leakage currents are allowed. The new FMBC LL series of filters is designed for rated currents between 7 and 180 A. It is ideal for leakage current-critical industrial applications such as drive technology.

Today's electrical industrial installations are increasingly being fitted with residual current devices (RCD) to ensure efficient personal protection. This is also a requirement in certain countries for 3-phase systems, for example plug-in systems up to 32 A. The RCD limits the current to earth to a maximum of 30 mA. This poses a particular problem in drive technology since the frequency inverters that control the engine generate considerable leakage current. Long motor cables further aggravate the problem since they increase the capacity to earth and hence the currents to earth too. The new series of FMBC LL filters helps reduce the leakage currents and permits compliance with common EMC standards as an efficient input filter.

The compact FMBC LL 3-phase filters have been designed for currents from 7 A to 180 A at an ambient temperature of 50 °C. They have UL approvals for ambient temperatures of +50 °C as well as +40 °C at a higher rated current. The FMBC LL is approved for rated voltages of 520 VAC. This means that they can be used in high-power systems, such as machines used in an industrial environment. Despite their high output performance, they are still compact and lightweight in design.

The standard FMBC LL is fitted with a screw connection. Other types of connections including wires or copper bars are possible on request as well as customised modifications to the circuit or housing. SCHURTER also offers its own EMC measuring service for an optimum adjustment to the inverter. Therefore the most efficient filter solution for the system can be developed.

> 5123: Compact filtered inlet boasts maximum attenuation
SCHURTER's latest 5123 series filtered inlet adds filter performance to the already successful standard version 5120 series. The higher attenuation in the same compact dimensions is designed to meet the continually increasing demands for interference suppression of IT, medical, test & measurement and industrial equipment. 

The new 5123 series filter combines an IEC power inlet and a line filter, designed for nominal currents up to 15A. The combination power entry unit integrates the EMC filter directly at the line input, providing an optimal effect on electromagnetic compatibility. The broad metal flange features a large amount of contact area, which further optimizes filtering and shielding effects. The filter’s increased inductance achieves a 6 dB improvement in asymmetric attenuation, compared to 5120 series and other like products on the market, corresponding to a doubling of its attenuation characteristics. Thus, the high filter performance makes the 5123 series well suited for applications such as switched-mode power supplies, where the utmost interference suppression is required.

The 5123 series is available for snap-in, screw-in or studded assembly. Screw-in assembly from the back side is particularly attractive for a plastic chassis with interior metal layers. Wiring is done with quick-connect, solder, stranded-wire or pc-board terminals. The PC version features snap-in feet for secure pc-board mounting. The stranded-wire version enables customer specific fitting for further cost-effective wiring.

The 5120 and enhanced 5123 are designed for operating current levels up to 10A at 250 VAC according to IEC and 15A at 125/250 VAC according to UL. They are ENEC and cURus approved. The two series are offered in standard and medical versions suitable for use in IT applications according to IEC 60950, and medical applications according to IEC 60601-1.

> C22F: Compact filtered inlet for high ambient temperatures
Given the high levels of integration in electronic systems, the demand for electrical components for use in higher temperature environments is continually increasing. This is where the new C22F appliance inlet and filter fills a gap. The first product of its type on the market performs exceptionally well in applications with higher ambient temperatures. 

The new C22F filter series combines an IEC C22 high temperature appliance connector with a high-quality power-line filter. The combined inlet and filter are especially suited for use in applications with nominal currents up to 16A at 75°C ambient and 20A at 65°C ambient. The unique design provides higher temperature ratings over comparable filtered inlets, while maintaining a similar compact size.

The combination power entry module integrates the EMC filter directly at the line input, providing an optimal effect on electromagnetic compatibility. The broad metal flange features a large amount of contact area, which further optimizes filtering and shielding effects. Wiring is done using quick-connect or solder terminals.

The standard C20F and new C22F series are designed for operating currents up to 16A at 250 VAC according to IEC standards and 20A at 125/250 VAC according to UL standards. They are ENEC and cURus approved. The two series are available in standard and medical versions suitable for applications according to IEC 60950, and medical applications according to IEC 60601-1. Such applications include power distribution units, servers, medical heating appliances and imaging systems.

> FMER SOL: High-current DC filters
SCHURTER is expanding its successful FMER series of high-current filters with a model for high power. The entire series is now available without grounding capacitors for safety-related applications. 

Photovoltaic panels with increasing surface areas are being installed, and as a result ever more powerful inverters are required. To address this trend, SCHURTER is expanding the current ratings of its DC filters to 2300 A for higher power. For reasons of safety, filters are sometimes requested without grounding capacitors, which prevents any leakage current to ground. Thus, SCHURTER is also offering this entire series without Y capacitors.

Modern solar inverters with MPP (maximum power point) trackers generate interference in both directions: on the AC grid side and the DC panel side. On the AC side, it is usual to insert an AC filter such as the SCHURTER FMAC or FMBC, but until now few provisions have been made for the DC side. EMC standards EN 61000-6-3 and EN 55014-1, however, also limit the level of interference on non grid-connected conductors such as those going to a solar panel. A remedy can be provided by DC filters installed on the DC side of the solar inverter.

Large solar inverters are generally housed in cabinets that must have active cooling. The SCHURTER FMER series features high temperature resistance, which reduces the necessary cooling energy and makes a significant contribution to higher energy efficiency for the entire system.

FMER family filters have UL approvals for ambient temperatures of +55°C and +75°C as well as for rated voltages of 600 VDC and 1000 VDC. They are exceptionally well suited for rated currents from 25 A to 2300 A at an ambient of 55°C and for voltages up to 1200 VDC.

FMER SOL DC filters come standard with screw terminals up to 150 A, and with copper bars starting at 250 A. Other connection types (stranded wire or copper bar for current levels less than 250 A or bus bar terminals) are available on request. In addition, small modifications to the switching or the housing are also possible on request.

For optimal matching to the inverter, SCURTER offers its own EMC measurement service that makes it possible to find the most cost-effective filter solution.

> FMCC SOL: 3-phase high-current filter
SCHURTER is expanding its successful FMER SOL DC filter with a series for applications using 3-phase AC. The new FMCC SOL high-performance filter series is designed for rated currents from 150 to 2500 A. The devices are ideal for increasingly powerful inverters that require filters on both the AC and DC sides. Large inverters find use in photovoltaics, wind energy systems as well as in industrial applications and quick-charge stations for electric vehicles.

The very high-performance FMCC SOL 3-phase high-current filters are designed to handle currents from 150 to 2500 A at an ambient temperature of 50 °C. With a voltage rating of 520 V or 760 V, they can be used in all high-performance systems such as inverters for photovoltaic and wind power systems. Despite this high performance, they feature a compact, lightweight design.

The amount of renewable energy is constantly growing. As a result, ever more powerful and physically larger systems are being built such as for photovoltaics and harvesting wind energy. All these systems need high-performance inverters that are designed for optimal energy efficiency. Modern inverters with MPP (maximum power point) trackers generate interference in both directions: on the AC grid side and the DC panel side. On the DC side, a filter in the FMER SOL series can be used for currents from 25 to 2300 A. These are enhanced very nicely on the AC side with the new FMCC SOL high-current series for 3-phase AC from 150 to 2500 A. Filtering on both sides of the connection lines helps to meet common EMC standards.

The FMCC SOL filter family has UL approvals for ambient temperatures of +50 °C as well as +40 °C with higher rated current. They are approved for voltage ratings of 520 VAC and 760 VAC. The high voltage rating of 760 VAC allows their use in IT power grids.

The FMC SOL up to 250 A is equipped standard with M10 screw connections and starting at 320 A with copper bars. Other connection types (stranded wire or copper bars for current levels less than 320 A) are available on request. In addition, customer modifications to the switching or the housing are also possible on request.

For optimal matching to the inverter, SCHURTER offers its own EMC measurement service. In this way, the most efficient filter solution for a system can be easily determined.

> Simple circuit simulation: SPICE library for common-mode chokes
To assist in the simulation of circuits, SCHURTER now offers SPICE libraries for common-mode chokes on circuit boards. 

The new SPICE library contains simulation models for all common-mode chokes on circuit boards up to a rated current of 10 A. Also included are example circuits with which it is possible to examine the operational properties of various chokes before they are actually used in the circuit.

The SPICE models help customers find the best product for their application. With the help of simulation, they can evaluate the behavior of the chokes and also carry out calculations. In modern electronic designs, it is very common to simulate circuits before actually building the hardware. This approach eliminates or reduces the effort needed to build prototypes, which saves time and money.

The library is simply copied into the corresponding directory of the SPICE application. In the circuit diagram of the SPICE application you can select and insert the desired choke from SCHURTER's product line. By clicking the mouse on the component, the desired item number is selected and the simulation is started. In addition, the library contains multiple example circuits for common-mode chokes. This makes it extremely easy to compare the operational properties of various chokes. An analysis of the frequency response and saturation is also possible.

The simulation models have been tested with LTspice but can also be used with other compatible SPICE programs. LTspice is a widely used freeware simulation tool from Linear Technology Corp.
