Our open case chassis mount transformers

Important Safety Information

All of our transformers will require additional wiring and protection that is available separately.

When mounted they should have adequate cooling ventilation and should be fully protected from accidental contact. If you are planning to show your layout, exhibition managers would prefer a metal insulated case, rather than wood.

The primary and secondary power inputs and outputs should be protected with a suitable fuse or circuit breaker.

These items are dangerous if not installed correctly. If you are unsure on how to wire these items safely, please consult a qualified electrician.

Railwayscenics supply a wide range of open case chassis mounting transformers in a wide range of power options. All of our supplied transformers have single primary windings and dual secondary windings, that can be wired in series or parallel.

What is a transformer?

A simple transformer consists of two electrical conductors called the primary winding and secondary winding, and a steel core that magnetically links them together.

These two windings can be considered as a pair of mutually coupled coils. Energy is coupled between the windings by the magnetic field that links both primary and secondary windings.

6VA transformers

These transformers should be used to power a small amount of very low consumption products such as LEDs and other lighting applications. They should be protected by a 3amp fused plug.

12VA transformers

These transformers should be used to power low consumption products such as LEDs and other lighting applications. They should be protected by a 3amp fused plug.

20VA transformers

These can be used for medium power requirements. They should be protected by a 5amp fused plug.

50VA transformers

These are used on high consumption electrics. They should be protected by a 5amp fused plug.
