New DIN Rail Mounted EMI Filter Series from API Eases Installation and Enhances EMI Protection for Improved EMC Compliance

26 June 2018

API Technologies Corp. (API), a provider of high-performance RF and microwave signal conditioning and electromagnetic spectrum management solutions, announced its new series of DIN rail mounted EMI filters for medical to metrology grade applications, featuring reduced installation complexity. API’s 62-STB series of DIN rail mounted, single phase power EMI filters eliminate both differential mode and common mode electromagnetic interference (EMI) and meet stringent electromagnetic compatibility (EMC) compliance specifications.

They are ideal for reducing unwanted interference for industrial applications and high-power office/medical equipment and instruments, such as:

* Test and measurement instruments

* Medical X-ray machines

* Medical bone mineral densitometry devices

* Electrical installation control panels

* Textile machinery

* Powered exercise equipment (treadmills and etc.)

* Electrical boilers and HVAC equipment

* Refrigeration units

* Printers

* Low and high voltage power supplies

The enhanced intelligence and performance requirements of new electronics bring greater susceptibility to outside EMI. In fact, the demand for EMC compliance in industrial, office and medical environments is Source: API Technologies Corp. Source: API Technologies Corp. intensifying as highly EMI-sensitive digital, analog and RF/microwave electronics are increasingly employed to enhance efficiency, reduce costs and enable innovative solutions. EMI power filters are a low-cost solution for designing in better EMC compliance or retrofitting existing equipment negatively impacted by EMI.

API’s DIN rail mounted EMI filters are easily integrated, installed and connected externally or internally to existing equipment, control panels and the power line. They also can be easily replaced, retrofit or serviced and mount to any DIN rail system. Several models include chassis mounting features for greater customization and utility.

API’s DIN rail mounted power filters feature 50/60 Hz rated voltage operation to 250 VAC; models in the series range from 6 A to 30 A maximum rated current. Though capable of substantial power handling, these EMI filters exhibit very low maximum leakage current, typically 0.5 mA at 250 VAC, with models available that reach a maximum of 0.1 mA. The EMI filters’ low maximum voltage drop is less than 1.0 V.

API’s DIN rail mounted noise filters demonstrate high insulated resistance of 300 MΩ at 500 VDC between the power line and ground. Moreover, these EMI filters are built to survive industrial temperatures, with an operating temperature range from -25° C to +85° C, including a maximum temperature rise of 45° C. They can be made with enhanced high-pulse and high-noise attenuation features to meet a wider range of operational requirements.

Key Performance Features:

* Easy connection and installation (Chassis or DIN rail mount)

* High reliability (high strength epoxy molded)

* High insulation resistance (300 MΩ between line and ground)

* Low leakage current versions (<0.1 mA at 250 VAC 60 Hz)

* 6 A to 30 A 250 VAC Models

* High pulse attenuation versions

* High noise attenuation versions

API’s DIN rail mounted EMI filters are safety agency approved, ruggedly manufactured with epoxy-molded housing. They are RoHS-compliant and designed to meet all applicable industrial standards.
