Understanding Isolation Transformers

Isolation transformers block transmission between the primary and secondary electrical circuits. They play a vital role in protecting the power supply and power supply lines, allowing the voltage to increase from one section to another.

An isolation transformer is critical for many types of equipment and installations.

Isolation Transformers

How Does an Isolation Transformer Work?

An isolation transformer is connected between the power supply (input) and an electrical circuit or device (output) to prevent electrical currents from traveling directly between circuits. This electrical isolation reduces the risk of equipment damage and protects people from electric shock.

Our transformers are designed to separate (isolate) a circuit from the supply. Typically a isolation transformer provide the same voltage at the output as the primary power supply voltage at the input, however, voltage conversion is also possible and common if needed. Their primary function is to achieve circuit separation by isolating the primary and secondary windings, enhancing safety, and reducing electrical noise.

Many transformers also include an electrostatic shield between the windings, which helps to block high-frequency noise from passing through to the output, offering additional protection for specialised equipment.

Isolation Transformers

Why Use Isolation Transformers?

Isolation transformers are essential for reducing common mode and differential noise in electrical circuits, often caused by outside interference or system imbalances. By isolating the primary and secondary windings, these transformers help prevent common mode electrical noise from causing distortions in connected devices. In some applications, a constant voltage transformer design is used to maintain a stable output where the supply may fluctuate.

Additionally, isolation transformers can include electrostatic shields between windings, which block high-frequency noise and reduce ground loop interference. This feature enhances system reliability, especially in applications with precision electronics.

Choosing the Right Commercial Isolation Transformer

When selecting an isolation transformer, ensure it meets the specific voltage, current, and power requirements of your application. The right transformer provides effective isolation and protection, tailored to the operational demands of your system.

Benefits of Isolation Transformers


Create a Safer Environment

They can help prevent electrical shocks and reduce electrical noise, to protect workers and clients from harm.

Protect Your Equipment

Isolation transformers can protect critical devices from damage, increasing their lifespan and effectiveness.

Reduced Noise

Isolation transformers reduce electromagnetic interference between circuits, thereby reducing noise in the system.

 Save on Costs

Isolation transformers are often more affordable than other power transformers, helping you save on costs and offering great value.
