Neptune’s Powernac Series Passive Harmonic Filters offer a cost-effective, all-passive solution for mitigating current harmonics in VFDs and 6-pulse diode rectifier loads. Guarantees THDi of 8% max at 50% load and 5% max at full load, meeting IEEE-519 voltage/current distortion limits. Rugged, maintenance-free, and reliable, it improves power factor, absorbs transients and surges, reduces harmonic-related heating, and lowers energy costs — outperforming 12-pulse/18-pulse reduction techniques.
