Engineered Power Magnetics Scope
AMP Magnetics is an independent manufacturer’s representative connecting OEM electrical builders, panel fabricators, and facility engineers with specialized domestic magnetics manufacturers.
Specialized Magnetic Components for Industrial Power
Power magnetics cannot be treated as off-the-shelf commodities. Extreme duty cycles, high-frequency harmonic distortion from solid-state drives, tight dimensional footprints, and harsh ambient environments require engineered solutions. Explore our represented product categories below:

Dry-Type Transformers
Standard and custom dry-type isolation, drive isolation, distribution, and specialty application transformers. Designed for non-linear loads with custom K-factor ratings, electrostatic shielding, and harsh-duty enclosure options.
| Typical Ratings | 15 kVA to 5,000+ kVA |
| Voltage Classes | Low Voltage (600V class) & Medium Voltage (up to 34.5 kV) |
| Applications | Drive Isolation, Substations, Automation Panels, Grounding |

Reactors & Inductors
3-phase AC line reactors, load reactors, DC link chokes, and high-frequency output inductors. Protect sensitive VFD electronics from utility transients while mitigating motor insulation breakdown caused by dv/dt reflected waves.
| Impedance Classes | 3% and 5% standard (custom impedances available) |
| Current Ratings | 2 Amps to 1,500+ Amps |
| Applications | Line side surge buffering, VFD input mitigation, long motor leads |

Harmonic Filters
Tuned passive harmonic filters, trap filters, and power quality magnetics engineered to meet IEEE 519-2022 standards. Prevent utility harmonic penalties, avoid transformer overheating, and eliminate drive tripping.
| Performance Target | < 5% THD-i at rated load |
| System Voltages | 208V, 240V, 380V, 480V, 600V, 60 Hz / 50 Hz |
| Applications | Water/wastewater pumps, oil & gas compressors, HVAC chillers |

Power Quality & Assemblies
Complementary OEM magnetics, power factor correction detuned reactors, transient voltage surge suppression magnetics, and engineered electrical sub-assemblies built to specification.
| Focus | Resonance suppression, power factor improvement, transient dampening |
| Integration | Open-core/coil for panel builders or integrated NEMA enclosures |
| Customization | Specific lead wire terminations, thermal sensor integration (PTC/RTD) |
18-Pulse Autotransformers
Phase-shifting autotransformers that feed multi-pulse drive rectifiers and cancel low-order harmonics at the source.
