Product Description:

The 1NF-10 mains electromagnetic interference filter is manufactured by Kollmorgen for the Mains EMI Filters series. Designed for single-phase supply lines, the unit is wired ahead of drives, controllers, or measurement equipment to suppress conducted noise and limit emissions returning to the power grid. Differential-mode and common-mode inductors work with metallized capacitors to help automated systems meet industrial electromagnetic compatibility limits. The filter also prevents disturbances from the incoming supply from reaching sensitive electronic components in motion-control systems.

The filter is rated for a nominal line voltage of 230 VAC at industrial frequencies of 50/60 Hz. At its reference ambient temperature, it carries a continuous load of 10 A at 40 °C with a series DC resistance of 2 × 29.5 mΩ, keeping the voltage drop across the device low. Leakage current to protective earth is limited to 0.48 mA, permitting connection to equipment that uses sensitive ground-fault monitoring. High-potential verification uses a line-to-earth withstand voltage of 2 kV AC for two seconds, while a separate line-to-neutral test applies 1.1 kV DC for the same duration.

Encapsulated polyurethane potting secures the internal elements against vibration and moisture, while the assembly meets climatic test class 25/100/21 for humidity and storage stress. Field wiring is completed through quick-connect tabs measuring 6.3 × 0.8 mm, and the IP20 touch-safe housing helps prevent accidental contact with live parts while allowing convection cooling. The filter operates continuously across an ambient temperature range of -25 to +100 °C, making it suitable for cabinets exposed to cold startups or elevated machine temperatures. Mechanical loading on a DIN rail or panel remains low because the unit weighs 0.285 kg, and its compact single-phase construction conserves installation space.
