We carry MTE Corporation — an industry leader in power quality solutions since 1982, with deep expertise in harmonic mitigation, motor protection, and VFD line conditioning.
Power Quality Solutions — Harmonic Filters & Reactors for VFD Applications
When it comes to power quality, AMPS carries MTE Corporation — an industry leader in power quality solutions founded in 1982, with decades of proven expertise in harmonic mitigation, motor protection, and VFD line conditioning. MTE’s product lineup is trusted across oil & gas, water/wastewater, HVAC, food & beverage, and industrial automation applications worldwide.
Poor power quality is one of the most overlooked causes of premature equipment failure, motor damage, and system downtime in industrial facilities. Harmonic distortion, voltage spikes, and switching transients generated by VFDs and power conversion equipment put stress on motors, drives, and electrical systems throughout your plant.
WHAT THEY DO
- Reduce harmonic distortion at the source
- Protect VFDs from power line disturbances
- Protect motors from reflected voltage spikes
- Extend service life of drives and motors
- Improve system efficiency and reduce utility penalties
COMMON APPLICATIONS
- VFD input and output conditioning
- Harmonic mitigation for plant distribution
- Motor protection for long cable runs
- Oil & gas and water/wastewater
- HVAC and building automation
Power Quality Filters
MTE’s passive harmonic filters — including the Matrix® AP, Matrix® E-Series, and Matrix® Air — reduce total harmonic current distortion (THID) at the source, protecting upstream electrical systems and improving overall power quality. The Matrix® AP features MTE’s patented Adaptive Passive Technology, delivering best-in-class harmonic mitigation for VFD applications.
What Power Quality Filters Do
- Reduce harmonic distortion generated by VFDs and power conversion equipment
- Protect upstream transformers, switchgear, and electrical infrastructure
- Improve system efficiency and reduce utility penalties for harmonic content
- Available for single-phase and three-phase applications
- Suitable for new installations and retrofit projects
Line & Load Reactors
MTE’s RL and RLW series line and load reactors provide essential protection on both the input (line side) and output (load side) of variable frequency drives. Line reactors reduce harmonic distortion and protect the drive from power line disturbances; load reactors protect the motor from reflected voltage spikes and dV/dt stress caused by long cable runs.
What Line & Load Reactors Do
- Absorb power line disturbances and reduce input harmonic distortion
- Protect VFDs from voltage spikes, surges, and notching
- Protect motors from reflected wave voltage and insulation stress
- Extend the service life of both drives and motors
- Simple, cost-effective solution for most VFD installations
At AMPS, we work directly with engineers, purchasing teams, and plant managers to make sure you get the right power quality solution for your application — not just whatever ships fastest. With deep inventory and hands-on technical support, we’re built to keep your projects moving.
