This product features a threepart circuit designed to improve power quality and protect DC power rails. Key components and structure Part 1: a singlestage filter circuit Part 2: a common mode filter Part 3: a twostage filter circuit The overall assembly is a passive filter built with inductors and capacitors, a traditional approach for harmonics compensation. What customers gain Harmonics reduction and DC power purification Filters out one or more harmonics in the power supply and helps clean the direct current power rail. Enhanced power integrity The multistage design provides effective attenuation of unwanted frequencies, contributing to steadier voltage and reduced ripple on DC rails. Quiet, reliable operation Passive LCbased filtering has no active components, offering dependable performance with low maintenance. Targeted suppression of fast disturbances Common mode filtering reduces fast interference that can occur at several kilohertz at specific locations, helping protect sensitive electronics. Compatibility and practical use Compatible with standard power supplies and DC rails where harmonics suppression and DC purification are required. Suitable for integration into systems where clean power delivery and EMI/EMC management are important. Use scenarios Industrial equipment power supplies Reduces harmonic content and stabilizes DC rails for better reliability of controllers and drives. Sensitive measurement and control systems Improves signal integrity by minimizing powerrelated noise on DC power lines. Electronics with EMI/EMC sensitivity Suppresses fast transients and common mode disturbances that can affect performance. Notes on attributes Function: harmonic filtering, common mode suppression, DC power purification Compatibility: designed for standard power and DC rails; easy to integrate into existing systems Performance: multistage passive LC filtering provides reliable attenuation of target frequencies without active components
