Parameters Parameter Specification Product Family AccuSine / SineWave / Passive Harmonic Filters Component Type 3-Phase De-Tuned Harmonic Filter Bank Commercial Reference METSEDM2365N Primary Function 1. Protect PFC Capacitors from harmonic currents and resonance. 2. Reduce Voltage Distortion (THDv) by providing a low-impedance path for specific harmonic currents. Rated Power / Current The numeric code "2365" likely encodes the reactive power rating (kvar) and/or the system current. It may indicate a unit rated for 65 kvar at a specific voltage (e.g., 400V) or a related current capacity. This must be confirmed from official data. System Voltage Typically for 400V AC, 50Hz or 480V AC, 60Hz three-phase systems. Tuning Frequency Commonly tuned to 4.2 (for dominant 5th harmonic mitigation) or 6.7 (for 7th harmonic). Filter Configuration Single-stage, de-tuned (series reactor + capacitor per phase). Total Harmonic Distortion of Voltage (THDv) Reduction Can typically reduce system voltage THD to < 5% under appropriate load conditions. Connection Three-phase, typically in Delta configuration for capacitors. Protection May include internal fuses, discharge resistors, and thermal protection. Enclosure IP20 or IP31 cabinet for indoor installation. Cooling Natural convection. Operating Temperature -5°C to +45°C (typical for capacitor-based equipment). Standards & Certifications CE, UL, cUL, IEC 60831, RoHS.
