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
Feedthrough Filters
Pulse Transformers

E-T-A Power Relays

Image

E-T-A Power relays are reliable problem solvers when it comes to switching high currents. Particularly construction machinery, agricultural vehicles as well as buses and trucks, floor-borne vehicles and other special vehicles (e.g. fire brigades) often have connected large electrical loads. In these applications, power relays disconnect the entire on-board electrical system from the battery.

Depending on the application, E-T-A offers purely electro-mechanical relays, solid state relays and also a hybrid design consisting of an electro-mechanical switching system with an intelligent electronic control unit.

ETA Power Relays

Key Product Lines & Features

  • EPR10 Solid-State Relays: Designed for high continuous currents (up to 200A at 24VDC), requiring 80% less space than traditional alternatives and
    eliminating the need for separate heat sinks
  • HPR10 Hybrid Relays: Combine robust mechanical, bistable switching with intelligent electronic controls, enabling features like on/off delays and voltage
    monitoring
  • MPR10/MPR20 Mechanical Relays: Bistable (MPR10) or monostable (MPR20) relays designed for high current switching with low power consumption

Key Advantages

  • Efficiency: Very low holding current reduces power consumption.
  • Durability: High resistance to environmental factors (IP57 rated for some models).
  • Maintenance: Long service life with reduced maintenance costs due to solid-state technology.
  • Functionality: Options for built-in overcurrent, short-circuit, and thermal load protection.

Applications

  • Battery Management
  • Power Distribution
  • Circuit Protection in Harsh High-Load Environments

Schurter

4770: Dual Block Outlet 16A

  • IEC 60320 type J 16 A, Dual
  • Available in black, white or grey
  • Snap-in version front side

The demand for higher power density in data centers and industrial environments is constantly growing. Schurter is responding to this development with the new 4770 dual block outlet, which is designed for a rated current of 16 A and optimized specifically for use in power distribution units (PDUs). The 4770 combines a robust design with easy installation.

Thanks to its dual block configuration, the outlet can be integrated into power distribution units (PDUs) in a space-saving manner. The proven snap-in mounting system ensures quick and secure installation and reduces installation effort.

The 4770 outlet is available in black, gray, or white, offering flexible design options for different applications (multi-phase systems). Various connection options (standard: QC 6.3 mm; QC 4.8 mm; solder connections, and PCB mounting available on request) allow easy adaptation to different wiring concepts. VDE, UL, and CCC certifications ensure international compliance and a high level of safety and reliability.

The dual outlet is designed for currents of up to 16 A at 250 VAC according to IEC and 20 A at 250 VAC according to UL. It is designed for an operating temperature range of –25 °C to +70 °C. Installation is via snap-in mounting (standard: wall thicknesses 1.2 mm and 1.5 mm, 0.8 mm to 3.0 mm on request).

The 4770 dual outlet is ideal for use in data centers, industrial plants, IoT infrastructures, and IT as well as telecommunication systems. In other words, wherever compact and powerful power distribution is required.
