Our custom Class 2 control transformers and high-reliability inductors maintain system stability across programmable logic controllers (PLCs), smart energy metering, commercial window control actuators, and lighting ballasts. In-house computer-aided modeling ensures optimal thermal management and ultra-low noise footprint.
Renewable Energy & Smart Grid Systems
Solar inverters, wind turbines, biomass energy plants, and battery energy storage systems (BESS) require magnetics capable of high frequency operation, low core loss, and high power density. Triad designs advanced magnetic solutions supporting the global transition toward decarbonized power infrastructure.
Engineering Solar & Wind Energy Reliability
Our custom boost inductors, toroidal power transformers, and EMI filtering chokes operate at elevated switching frequencies with high efficiency, reducing heat dissipation and maximizing system ROI. We engineer magnetic components for grid-tied inverters, energy converters, and intelligent power monitoring panels.
Medical Equipment & Healthcare Devices
Medical electronics demand absolute safety, strict regulatory compliance, and near-zero failure tolerance. Triad Magnetics manufactures medical-grade transformers and power supplies specifically engineered to satisfy stringent IEC 60601-1 isolation and minimal leakage current benchmarks.
Ultra-Low Leakage & High Isolation Standards
From patient monitoring consoles and diagnostic imaging devices to surgical equipment and laboratory analyzers, our custom medical isolation transformers integrate advanced dielectric shielding and reinforced insulation systems to protect patients and clinical operators worldwide.
Power Conversion & Measurement
Modern power distribution networks demand precise current monitoring and energy-efficient DC-DC and AC-DC power conversion. Triad engineers high-precision current sense transformers, planar magnetics, and switch-mode transformers built for optimal power factor performance.
High-Precision Electromagnetic Sensing
Our current sensing transformers provide reliable signal measurement across power management systems, sub-metering grids, and overload protection circuits. Designed for high accuracy across wide frequency spectrums, Triad power components enable peak operational performance.
Professional Audio & Sound Processing
Triad Magnetics holds legendary status in sound amplification and audio broadcast history. Having pioneered high-wattage output audio transformers in the 1950s for sound icon Dick Dale and early Fender amplifiers, Triad remains the premier choice for premium audio engineers.
Ultra-Low Distortion Signal Isolation
We manufacture custom PCB-mount and chassis-mount audio transformers engineered for minimal total harmonic distortion (THD), flat frequency response, and maximum common-mode rejection (CMRR). Applications include studio recording consoles, broadcast equipment, and high-end valve amplification.
Food & Beverage Commercial Equipment
Industrial food preparation and beverage dispensation equipment rely on consistent power quality to maintain precise temperature parameters and prevent costly downtime. Electrical component failure risks ingredient spoilage and violation of health safety standards.
UL Class 2 Certified Thermal Durability
Triad produces rugged UL-recognized Class 2 and Class 3 power transformers, wall plug-in power supplies, and sealed inductors resistant to high humidity, grease vapor, and ambient washdown exposure common in commercial kitchens and processing plants.
Transportation & EV Infrastructure
The global acceleration of vehicle electrification requires innovative magnetics engineered for high power transfer efficiency, reduced electromagnetic interference (EMI), and compact footprint within EV charging stations, battery management systems (BMS), and onboard electronics.
Magnetics for the Electric Mobility Era
Triad designs custom high-frequency inductors, common-mode chokes, and power isolation transformers utilized in commercial e-mobility networks, EV Level 2 / Level 3 fast-charging infrastructure, rail transportation systems, and marine electronic controls.
