Driving Transportation Forward with Reliable Transformer Solutions

At Astrodyne TDI, we design and manufacture single-phase and three-phase transformers and inductors, available in both toroidal and EI laminated constructions, engineered for the transportation industry. 

Our products combine compliance, performance, and durability to keep critical systems operating safely and efficiently — even in the toughest environments.

Powering Critical Transportation Systems 

Transportation systems demand dependable power. From freight movement to urban transit, equipment must perform flawlessly under constant stress. 

Power interruptions can mean spoiled cargo, operational downtime, passenger discomfort, or even safety risks. That’s why our transformers and inductors are designed for reliability in a wide range of transportation applications, including: 

• Truck Refrigeration Systems – Step-down voltage designs deliver efficient, around-the-clock operation to protect perishable cargo. 

• Locomotive Cooling & Heating – High efficiency ensures reliable performance in heavy-duty rail cooling and heating systems. 

• Traffic Control & Signaling – Compact, low-profile transformers save cabinet space while delivering dependable traffic control power solutions. 

• Onboard Auxiliary Systems – Step-down power for electronics, lighting, and controls in buses, trains, and specialty vehicles. 

• Charging & Electrification Infrastructure – Stable, efficient power conversion for the industry’s transition to electric mobility. 
  

Designed for Performance and Value 

Our solutions are built with both engineering precision and business value in mind: 

• Multiple output voltage options for diverse system needs. 

• Step-down voltage designs for safe, efficient power conversion. 

• High efficiency for demanding electrical environments. 

• Low-profile construction for compact, space-limited layouts. 

• Energy-efficient designs that reduce losses and lower costs. 

• Thermal & overload protection to extend equipment life and minimize downtime. 

Compliance & Quality 

When choosing transformers for transportation systems, compliance and reliability are non-negotiable. Every Astrodyne TDI product is built to meet international standards, giving you confidence in performance and safety: 

• UL / CSA / CE certifications for global regulatory compliance. 

• RoHS & REACH compliance for environmentally responsible design. 

• ISO 9001-certified manufacturing to ensure consistent quality. 

• Custom validation testing, including dielectric testing, induced voltage test, impulse test, polarity/phase test, partial discharge and load performance verification.
