3-Phase Passive Harmonic Mitigation Filters for Variable Speed Drives.
Will reduce harmonics to meet IEEE Std 519 limits where VFD’s are used for Water / Waste Water, Oil & Gas, HVAC systems, etc. Exceeds 18-pulse performance in a smaller footprint, at lower cost and without sacrificing energy efficiency.

SOLV™
A powerful harmonics analysis software program.
This complimentary software is a valuable tool for consulting and specifying engineers, utility operators and OEMs who need to evaluate and compare solutions for treating harmonics in VFD applications.


1-phase to Quasi 3-phase harmonic filter for 3-phase VFD’s where only 1-phase power is available. Reduces ITHD to <12% while allowing for less derating of VFD.
Used to lower current distortion and reduce the need for VFD derating in remote or residential locations where only 1-phase power is available and 3-phase motors are required. Applications include irrigation, waste water, Oil and Gas pumps, etc.


Low Voltage AutoTransformer with LINEATOR™ Harmonic Filter.
A low voltage AutoTransformer with built-in Lineator™ harmonic filter that offers multi-pulse performance for 6-pulse Variable Speed Drives on low voltage applications where the VFD voltage rating is different than the service voltage – addressing  the need for either  step-down or step-up line voltage transformation.

GENLINK™
A multiple winding reactor that is installed in the common neutral of paralleled sources. Adds impedance to block the flow of circulating currents, eliminates generator overheating and false protection trips caused by these currents.
For both 3-wire and 4-wire systems. GENLINK DPNL is used when two or more generators of dissimilar pitch are paralleled together or a generator is paralleled with an alternative source, such as the Utility.


High Efficiency Transformers that maximize energy efficiency, exceed NEMA Premium and other industry standards, provide quicker payback and are real-word tested.
Ideal for K-12 and Higher Education, Government, Healthcare, Commercial, Industrial, Data Center, Alternative Energy and LEED applications.
