EMC Filters

What is are EMC Filters?

An EMC or EMI filter is an electronic device used to reduce electromagnetic interference (EMI) in a power supply. It is typically used in power supplies, such as those found in computers, TVs and other electronic devices. The filter works by blocking the high-frequency noise generated by the power supply, allowing the device to operate more efficiently and with less interference.

What Do We Supply?

We supply an extensive range of EMC filters, including:
DC Filters
Single-Phase Filters
3-Phase Filters
IEC Inlet Filters and Modules
EMC/IEC Chokes
PCB Filters

Schurter 5180 Series Appliance Inlet Filter IP67

Schurter 5180

Appliance inlet filter with high protection against dust and water

  • IP67 towards the housing
  • IP54 for the corded connection
  • Filter version with high attenuation
  • V-Lock cord retention

Protection against dirt particles and moisture is becoming increasingly important. With product type 5180 and the associated V-Lock power cord, Schurter is launching an IP54 device connection that meets even the most demanding requirements.

The newly developed Schurter 5180 is a appliance inlet with filter in accordance with IEC 60320 and IEC 60529. Thanks to several seals, the built-in device plug provides IP67 protection for the housing. In combination with the corresponding V-Lock power cord, a protection rating of IP54 is achieved when plugged in. This rating offers excellent protection against dust particles and is splash-proof.

Special Sealing Gaskets
The blue colour of the V-Lock cable socket alone indicates that something is different here. Both the device plug and the power cord have been equipped with special sealing elements to achieve a high IP protection rating. The new blue V-Lock cable ensures reliable pull-out protection and tightness.

Standard and High-Performance Versions
Standard and high-performance versions are available. The latter are equipped with nanocrystalline cores in the chokes.

Green Line
The new 5180 device connector filter is also available in a version made from plant-based plastic. This significantly reduces the component's CO2 emissions.

Application Areas
Wherever dirt, dust particles, or splashing water may occur, the new Schurter technology is the perfect choice. This can be the case in harsh working environments in industry. In the medical field, a higher IP protection class is required. This is because medical devices must be cleaned, disinfected, and even sterilized regularly if necessary. Similar requirements apply in the food industry. Medicine 2 MOPP for applications with direct patient contact and, for example, ambulance vehicles or in the home care sector.

Schurter alo series

ALO – High Performance Fuse for EV Applications

  • Rated voltage up to 1000 VDC
  • Breaking capacity up to 50 kA
  • Three different mounting options
  • Highest security thanks to proprietary housing technology

The new Schurter ALO series has been specially developed for high-voltage electric vehicle applications and covers voltages up to 1000 VDC and currents up to 900 amps. With a high breaking capacity of up to 50 kA and the option of axial or bottom bolt-on mounting – available in either ceramic or resin housings – it offers maximum design flexibility.

The product line is available in a variety of voltage ratings from 250 to 1000 VDC and covers current ranges from 100 to 900 A. It is designed for an operating temperature range of -40 to +125 °C. The housing materials are ceramic or resin, and the end caps are made of a tin-coated copper alloy.

Wide Range
A key advantage of the series is its wide range of products, which covers different designs, voltages, currents, and mounting methods, significantly reducing design effort for customers. Its robust construction ensures reliability in harsh environments and minimizes the risk of housing cracks, terminal detachment, or resistance fluctuations. Safety is enhanced by proprietary filling and curing technology that prevents explosions, reduces fire hazards, and protects adjacent components from splinters.

Application Areas
Typical applications for the ALO series include PDUs, battery disconnect units, manual service disconnectors, all-in-one controllers, 2-in-1 electric drives, and battery management systems. The ALO series complies with the JASO D622, ISO 8820-8, GB/T 31465.6, and UL 248-20 standards, with the ALO11, ALO12, and ALO14 models already UL-certified.

This makes it a reliable choice for high-voltage protection in modern electric vehicle systems:
powerful, safe, and customizable.
