RS PRO DIN Rail Isolation Transformer, Primary voltage 230, 245, 400, 415 V ac, Secondary voltage ± 24 V ac

It has been over 100 years since the introduction of the first commercial Transformer when the mass production began. Since then, many additional modifications we developed to support various applications, such as electromagnetic, relays, pumps or heating elements.


The functionality of the Isolation Transformer has a concept to provide galvanic isolation between the AC power lines (mains) and the connected device, meaning no a DC can cross between the windings.

Today, we are proudly introducing our own branded RS PRO Isolation Transformer with a screw connector for multiple input and brackets for screw fixation. The exceptional isolating property and safety of our Transformer provide step up or step down of line (mains) voltages while reducing the noise coming from the primary to secondary or opposite.

The Isolation Transformers supports different types of equipment, from testing power-related devices to medical isolation equipment. However, they must meet rigorous electrical requirements to make sure no leakage current is in place.

Features and Benefits

  • 100% electrical and flash tested following BS EN 61558-1 regulations

  • Our Transformer provides high-quality safety and isolating properties for use in control circuits and general applications

  • Exceptional low loss noise laminations characterising our Isolation Transformer

  • Thanks to the dual standard primary winding 230/400 V ac with +15 V tap creates input flexibility to your equipment

  • The Transformer has an earth terminal provided whereas the dual secondaries are centre tapped

  • The Isolation Transformer has reliable protection against humidity and rusting thanks to varnish impregnation

  • The Transformer is fully shrouded cage clamp terminal with the voltage markings

  • All the crucial technical information is available on the permanent label attached

  • The Isolation Transformer provides high efficiency with a low regulation design


The Transformer with isolating properties has an association with the following applications:

  • Medical industry

  • Testing power devices

  • where transfer power between two circuits is mandatory


RS PRO is our own-brand range of great-value products. Each part of every RS PRO product is stringently tested against demanding industry standards. We give it our seal of approval only when we're confident of exceptional quality. That's why RS PRO is trusted by engineers worldwide.
