NF016-443
NF016-443 is a three-phase EMC line filter produced by SEW-EURODRIVE. It is mounted on the input side of variable frequency drives and servo drive systems. This component suppresses high-frequency conducted interference generated by drive units, and also shields the whole system from electrical noise and voltage fluctuations from the public power grid. It is a standard accessory paired with SEW MOVIAXIS, MDX and other drive series, helping industrial equipment fulfill relevant electromagnetic compatibility requirements.
Description
Model Explanation
NF refers to power line filter. The figure 016 stands for the rated continuous operating current of 16 amperes. The code 443 means this filter is developed for three-phase power supply systems with an operating voltage range from 380 VAC to 440 VAC.
Technical Specifications
The manufacturer of this product is SEW-EURODRIVE, and the official part number is NF016-443. Its rated input voltage covers three-phase alternating current from 380 V to 440 V, with an operating frequency of 50 Hz or 60 Hz. The rated continuous current is 16 A, and it is applicable to drive equipment with a rated power around 7.5 kW. It is designed as a three-stage EMC filter with integrated common-mode and differential-mode noise suppression circuits. The protection class is IP20. The filter adopts standard DIN rail installation inside control cabinets. Its total weight is approximately 1.6 kilograms. This product has obtained CE, UL and RoHS certifications.
Key Features
This filter delivers outstanding noise attenuation performance for high-frequency signals ranging from 150 kHz to 30 MHz, and effectively cuts down the total harmonic distortion of the power circuit. It realizes bidirectional interference isolation. It prevents high-frequency noise produced by inverters and servo drives from flowing back to the power grid, and meanwhile stops grid interference from affecting the stable operation of drive systems. With a compact and durable structure, it fits well in standard control cabinets and maintains stable performance during long-term continuous operation. It enables the complete machine to comply with EMC regulations specified in EN 61800-3, and simplifies the overall EMC design and on-site commissioning work.
Applications
This line filter is widely used for medium-power servo systems and frequency converter systems in industrial automation fields. Typical application equipment includes packaging machines, material handling devices, general machine tools, automated assembly lines and conveyor systems. It is the preferred matching component for SEW medium-power drive products such as MOVIAXIS and MDX series in industrial sites that require strict electromagnetic compatibility.
