PAD – Serial Passive Harmonic Filter
Ensuring stable power quality by filtering harmonics using robust serial passive filters, designed for industrial environments and nonlinear loads.

What is PAD?
PAD is a serial passive harmonic filter that effectively reduces harmonic distortion (THDI ≤ ۵%) by filtering the 5th and higher-order harmonics. Suitable for a wide range of power systems from 18kW to 1000kW.
Core Benefits
- Eliminates 5th, 7th, 9th, 11th, 13th and higher harmonics
- Reduces THDI to ≤۵%
- Robust capacitor and reactor design
- IP00 to IP54 enclosure options
- Natural or forced cooling
