Schurter expands its wide range of current compensated chokes with high current types for PCB mounting. The new DKIH series are available for single and three phase applications with rated currents from 10 to 50 amperes. Due to its open design, the chokes are light weight and compact, ideally designed to suppress EMI noise caused by power applications on the PCB.

Like all other aspects of electronic design, the power portion is oftentimes built today using discrete components on printed circuit boards. With the trending integration of components, to achieve smaller and smaller form factors, thermal problems and high currents on the PCB can arise. It also becomes increasingly challenging to meet EMC requirements with a filter package due to the resulting space constraints; therefore a filter on PCB with discrete components is a good solution. Next, the capacitors and a common mode choke, with asymmetrical effective inductance, are very effective to dampen EMI noise.

The new DKIH-1 series is suitable for single phase AC or DC applications from 10 up to 50 amperes. Light weight and compact, the common mode chokes are easily placed on the PCB with through hole technology (THT). They are designed and approved according IEC 60938, UL 1283 and CSA 22.2 no. 8. The voltage rating is 300 VAC (IEC, UL) and 250 VAC (CSA).

The new DKIH-3 series is suitable for three phase AC applications from 10 up to 50 amperes. The common mode chokes are also designed according IEC 60938 and are rated 600 VAC, making them suitable for many applications.

The DKIH-1 and -3 have a wide temperature range of -40 to +100°C. They are available with a standard pin out or customer specific pin out. Variations in the winding are also available on request.

Compact, High Performance Fuse is Optimal for Intrinsically Safe Applications

Schurter's Universal Modular fuse, UMT-H, offers a 1500 A breaking capacity at rated voltages of 277 VAC / 250 VDC. The compact, high performance fuse now has VDE approval in addition to UL approval. This time-lag fuse provides overcurrent and short circuit protection in various industrial control applications, including intrinsically safe applications.

The "intrinsic safety" method is one of the most common techniques used for achieving safety protection with lower voltage or power equipment. This method restricts the available electrical and thermal energy in a system so that ignition of a hazardous atmosphere (such as explosive gas, dust, or electrical arcing) cannot occur. The UMT-H's high breaking capacity of 1500 A, plus the >10 mm spacing between end caps, combined with the ability to be impermeable to conformal coating makes the fuse suitable for use in such intrinsically safe applications.

The UMT-H fuse is available in a total of 19 rated currents between 160 mA and 10 A at voltages up to 277 VAC and 250 VDC. The UMT-H measures at 5.3 x 16 mm, which is a smaller alternative to the classic cylindrically-shaped cartridge fuses (e.g. 5 x 20 mm). The smaller footprint saves valuable board space, allowing for further downsizing of equipment. With its square design, the UMT-H is also suited for more cost-effective, automated assembly. The high breaking capacity fuse meets the IEC 60127-7/1, UL 248-14 and CSA C22.2 standards along with its VDE and UL approvals. Additional applications include power supplies, electromobility, medical and telecommunication applications as well as 277 VAC utility-connected equipment.

Schurter is expanding its range of block filters for single-phase systems with its new FMAB NEO series. This range of single-phase filters combines a compact design with a high level of performance. The use of large X capacitors permits high symmetrical attenuation.

The new FMAB NEO filter series boasts a compact design combined with high performance. All versions come with large X capacitors, which ensure high symmetrical attenuation in the lower frequency range. Symmetrical interferences can occur because of phase-angle controllers or semi-conductor relays, for example. When the power semiconductors switch, they generate interference currents between the phase conductor and the neutral conductor. These are known as symmetrical interferences, which the X capacitors positioned between these conductors can help reduce effectively.

The filters in the new series have a shiny steel housing with a closed filter base. The filter is thus effectively and completely shielded, no matter how it is mounted. The filter series is particularly suitable for equipment with high symmetrical interferences, such as devices with semiconductors that control high-power equipment such as professional coffee machines, devices with water heaters, and all types of industry electronics. The compact filters are also suitable for medical equipment and household appliances.

The filter series is available with plug-in connections or thread bolts (30 A version). A version with wire connection is also available. They have a metal flange for easy screw-on mounting on the housing.

The series of devices is designed for current levels from 1 A to 30 A at 250 VAC according to IEC and UL standards. It has ENEC and cURus approvals and is suited for applications according to IEC 60950. Versions are available with small leakage currents <80 μA (M80) or without leakage current <5 μA (M5) for medical equipment according to IEC/UL 60601-1.

Technical Data:
- 250 VAC single-phase block filter
- Single-stage filter with large X-capacitors
- Excellent symmetrical attenuation
- Filter available ins standard or medical M5 / M80 version
- Rated currents: 1, 3, 4, 6, 8, 10, 12, 16, 20, 30A (ENEC / UL / CSA) at 40°C

Schurter's popular power entry module, KFA series, is now equipped with an additional ground line choke to suppress high frequency interference arising from ground loops on the ground line. In addition, the newly added ground line choke improves asymmetric attenuation in higher frequencies in medical filter versions. The KFA series with existing common-mode choke on the phase and neutral conductors, together with an additional ground line choke, is well enhanced to address the growing EMC challenges facing compliance engineers today.

Ground loops arise through different impedances of different ground line connections in one or multiple pieces of equipment. While all ground connections have the same potential level for the 50 Hz load current, these can have different potential levels for high-frequency interference. The ground line choke,  which is wired between the power-inlet connector and the filter output, smartly addresses this phenomenon. Because of its placement directly at the power line input, high-frequency interference currents on the ground line are prevented from bypassing the filter through the equipment housing. The ground line choke isolates the equipment chassis against high frequencies and the equipment ground from the ground on the line power connection. This approach effectively breaks any possible ground loops.

Audio equipment for instance is known for being prone to ground loop problems. Often referred to as hum or buzz, the KFA, with ground line choke, is well suited for suppressing interferences that lead to diminished sound quality. The KFA is also well suited for medical equipment required to use low leakage
filters for increased patient safety. The reduced Y capacitance to ground, or absence thereof, leads to reduced asymmetric attenuation in higher frequencies. The KFA with ground line choke helps to compensate for this reduced performance.

The KFA power entry module includes an IEC C14 power inlet connector with a 1- or 2-pole fuseholder and EMC filter and is available in a wide range of models and designs. The series offers current levels from 1A to 10A at 250 VAC according to IEC and UL standards. The series has ENEC and cURus approvals and is suited for applications according to IEC 60950. Special filter versions, M5 and M80, are available for medical devices according to IEC 60601-1. Wiring is done using quick-connect terminals or wire leads. The KFA is compatible with V-Lock cord sets, designed to safeguard against unintentional disconnection of the power.
