In manufacturing, transformers ensure stable, reliable power distribution for control circuits, machinery, and automation systems. In this guide, we explore the various types of industrial control power transformers, their applications, and key features.
Procurement professionals can use this summary to choose the most useful and cost-effective transformers for their facility’s equipment.
Power Controls in Manufacturing Plants
Power controls in manufacturing manage the distribution and regulation of electricity to machinery, automation systems, and auxiliary equipment. Components include motor controllers, PLCs, relays, contactors, and industrial control transformers—ensuring stable voltage, system protection, and energy efficiency.
Transformers are critical for voltage regulation, circuit isolation, and adapting power to specific operational needs. Below, we list the types of industrial control power transformers and their role in smooth manufacturing processes.
Most Common Types of Industrial Control Power Transformers
1. Step-Down Transformers
Step-down transformers are used in manufacturing environments where high input voltages need to be reduced to lower, usable levels for control circuits. Commonly used for converting 480V to 120V, these transformers are vital in motor controllers, CNC machines, and automation systems.
Also known as: Voltage-reducing transformers, reduction transformers.
2. Isolation Transformers
Isolation transformers electrically separate the input and output, to protect sensitive equipment from electrical noise, surges, and transients. They are commonly used in environments with high electronic interference, such as robotic systems and PLCs.
Also known as: Galvanic isolation transformers, safety transformers.
3. Autotransformers
Autotransformers are compact, cost-effective solutions for specific voltage regulation applications. Unlike isolation transformers, they do not provide electrical separation between circuits. They are suitable for stable environments where space and cost efficiency are priorities.
Also known as: Auto-transformers, variable transformers.
4. Standard Industrial Control Transformers
Designed for general-purpose applications, standard industrial control transformers provide reliable voltage regulation for most control circuits. They are versatile, supporting a wide range of industrial machinery and automation equipment.
Also known as: Control circuit transformers, general-purpose transformers.
5. Encapsulated Transformers
Encapsulated transformers are sealed in protective resin, making them ideal for harsh environments exposed to dust, moisture, and corrosive materials. This design ensures longevity and consistent performance in rugged conditions.
Also known as: Potted transformers, sealed transformers.
6. Multi-Tap Transformers
Multi-tap transformers offer flexibility with multiple primary or secondary voltage configurations. This design makes them well-suited for systems requiring different voltage inputs or outputs, reducing the need for multiple transformers.
Also known as: Variable-tap transformers, adjustable voltage transformers.
7. Energy-Efficient Transformers
Energy-efficient transformers are designed to minimize power loss and feature optimized core materials and windings. These transformers help reduce operational costs while maintaining performance, making them ideal for energy-conscious manufacturing facilities.
Also known as: High-efficiency transformers, low-loss transformers.
8. Phase-Shifting Transformers
Phase-shifting transformers are designed to optimize power flow and improve the efficiency of manufacturing power systems. They enhance grid stability and operational flexibility, making them ideal for large-scale industrial facilities with complex energy demands. Their compact design minimizes noise while supporting high-capacity operations.
Also known as: Load flow control transformers, power flow regulating transformers.
How to Choose the Right Transformer for a Manufacturing Facility
Selecting the right transformer depends on your specific manufacturing needs:
- Voltage Requirements: Ensure compatibility with your system’s input and output voltages.
- Environmental Conditions: Consider encapsulated models for harsh environments.
- Efficiency Goals: Choose energy-efficient transformers to reduce long-term costs.
