Auto-Transformers

Tested, Certified Auto Transformers In Stock

Looking for Auto Transformers? We’ve got them in stock for industrial and commercial including new, refurbished, reconditioned, and obsolete auto transformers. Electrical transformer safety is always a priority, so each auto transformer goes through electrical testing procedures for optimal performance and reliability.

Auto transformers with single winding are a compact and cost-effective solution compared to traditional transformers, like Medium Voltage Transformers and Low Voltage transformers. Single windings mean a smaller physical footprint. This makes them particularly useful in applications where space and cost considerations are important factors. Medium and Low Voltage transformers with separate primary and secondary windings are designed for stepping up or stepping down voltage levels.

What to Know: Selecting Auto Transformers for Industrial or Commercial Applications

Coils: How many coils does this auto transformer have, and what is their configuration?

Coil configuration affects the transformer's efficiency, voltage regulation, and overall performance. Different coil arrangements for different applications means better power distribution and stability.

Condition: What is the current condition of the auto transformer, including any refurbishments or reconditioning?

Knowing the condition of the transformer is vital for assessing its reliability and longevity. Refurbished or reconditioned transformers offer cost-effective alternatives without compromising performance.

Horsepower: What is the horsepower rating of this auto transformer?

Horsepower directly correlates with the transformer's capacity to handle the electrical load of industrial machinery. Choosing a transformer with the appropriate horsepower rating means compatibility and prevents overloading, protecting the transformer and your equipment.

Indoor/Outdoor: Is this auto transformer suitable for indoor or outdoor use?

Knowing whether the transformer is designed for indoor or outdoor applications determines environmental durability needed and safety features. Factors such as weatherproofing, insulation, and enclosure design vary between indoor and outdoor transformers.

KVA: What is the KVA (kilovolt-ampere) rating of this auto transformer?

The KVA rating indicates the transformer's maximum capacity to handle electrical power, considering both voltage and current. Choosing a transformer with the correct KVA rating gives you sufficient power to machinery while preventing overloads.

Phase: How many phases does this auto transformer support?

Understanding the phase configuration leads to compatibility with the electrical system. Single-phase or three-phase, selecting the correct phase configuration delivers seamless integration and efficient power distribution.

Primary Voltage: What is the primary voltage rating of this auto transformer?

Knowing the primary voltage rating supports compatibility with the electrical infrastructure. Matching the transformer's primary voltage to the available power source prevents voltage mismatches, for safe and efficient operation while avoiding potential damage to the transformer and connected equipment.

Secondary Voltage: What is the secondary voltage output of this auto transformer?

Secondary voltage output is crucial for compatibility with the voltage requirements of the industrial machinery it powers. Matching the transformer's secondary voltage to the machinery's specifications gives the best performance and avoids potential damage or malfunction.

Voltage: What is the voltage regulation capability of this auto transformer?

Voltage regulation refers to the transformer's ability to have stable output voltage under varying load conditions. Knowing the voltage regulation capability is important for consistent and reliable power supply, minimizing voltage fluctuations.
