Variable Transformers

Variable Transformers in the North East

At Watts Control Ltd, we manufacture and supply high-quality variable transformers for customers throughout the North East and across the UK. Designed to provide adjustable output voltages, variable transformers offer a flexible and reliable solution for applications requiring precise voltage control.

Used across industrial, commercial, educational, and testing environments, variable transformers enable users to smoothly and accurately increase or decrease output voltage to suit specific equipment and operational requirements.

What Are Variable Transformers?

Variable transformers, often referred to as variacs, are electrical devices that allow users to adjust the output voltage from zero up to, and in some cases above, the incoming supply voltage. Unlike standard transformers with a fixed output, variable transformers provide continuous voltage adjustment, making them ideal for testing, calibration, research and manufacturing applications.

Variable transformers are commonly used wherever precise voltage regulation is required, helping protect equipment and allowing operators to control electrical performance safely and efficiently.

Open-Style Single Phase Variable Transformers

Open-style single phase variable transformers are designed for applications requiring adjustable voltage from a standard single-phase power supply. Their open-frame construction allows easy integration into larger systems, panels and specialist equipment.

Key Features

  • Smooth and accurate voltage adjustment
  • Single-phase operation
  • Open-frame design for integration into equipment
  • Suitable for testing and laboratory environments
  • Reliable and efficient performance
  • Easy access for installation and maintenance

 

These variable transformers are commonly used in research facilities, educational institutions, manufacturing environments and electrical testing applications throughout the North East.

Open-Style Three Phase Variable Transformers

Open-style three phase variable transformers provide adjustable voltage control across three-phase electrical systems. They are ideal for industrial environments where large equipment requires precise voltage regulation.

Key Features

  • Adjustable three-phase voltage output
  • Suitable for industrial and commercial applications
  • Balanced voltage control across all phases
  • Open construction for system integration
  • High efficiency and reliable operation
  • Designed for demanding electrical environments

 

Open style three phase variable transformers are frequently used in production facilities, engineering workshops and industrial testing environments.

Enclosed Style Single Phase Variable Transformers

Enclosed style single phase variable transformers offer the same adjustable voltage control as open-style units but are housed within a protective enclosure for enhanced safety and durability.

Key Features

  • Fully enclosed protective housing
  • Adjustable single-phase voltage output
  • Improved operator safety
  • Protection against accidental contact
  • Robust and durable construction
  • Suitable for workshops and industrial environments

 

The enclosed design makes these variable transformers particularly suitable for locations where equipment protection and user safety are key considerations.

Enclosed Style Three Phase Variable Transformers

Enclosed style three phase variable transformers combine the benefits of three-phase voltage control with the added protection of a secure enclosure. They are designed for demanding industrial applications where safety, reliability and performance are essential.

Key Features

  • Adjustable three-phase voltage control
  • Protective enclosure for enhanced safety
  • Suitable for industrial and manufacturing environments
  • Durable construction for long-term use
  • Reliable voltage regulation
  • Reduced risk of environmental contamination

 

These units are often selected for factory installations, test facilities and engineering operations requiring dependable three-phase voltage adjustment.

Bench-Top Variable Transformers

Bench-top variable transformers are compact, self-contained units designed for convenient use on workbenches, testing stations and laboratory environments. Their portable design makes them ideal for applications where adjustable voltage is regularly required.

Key Features

  • Compact and convenient bench-top design
  • Simple voltage adjustment controls
  • Suitable for testing and development work
  • Portable and easy to position
  • Reliable output regulation
  • Ideal for laboratories, workshops and educational settings

 

Bench-top variable transformers are widely used by engineers, technicians and researchers who require precise voltage control during testing, product development and fault-finding activities.
