Isolating transformers with protective separation

TRAMAG products explained


Isolating transformers provide safety where reliable protective separation of circuits is necessary. They thus ensure the reliable and safe power supply of machines, systems and plants.

The TRAMAG isolating transformers translate alternating voltage and alternating current with at least one primary winding on the input side and one secondary winding on the output side by electromagnetic induction, at the corresponding reference frequency.

Due to their characteristic, they transform the mains input voltage one-to-one to the output winding, which ensures safe galvanic isolation from the supply network. Our isolating transformers achieve a voltage range of up to 1,000V and a power rating of 1MVA. They are also subject to a higher test voltage with correspondingly larger distances (creepage and clearance distances).

Our isolating transformers comply with the following standards:

  • DIN EN 61558-1
  • DIN EN 61558-2-4
  • UL/CSA

With TRAMAG isolating transformers, designs are possible both in IP00 and for higher degrees of protection. Customers all over the world have been relying on TRAMAG isolating transformers for years.

Quality is when your QMB goes “High-Five-S” with you

We know where quality must ultimately be demonstrated and proven: In the product, in the customer’s application. But where does quality begin? On the one hand in technical development and on the other hand in the organization of workplaces in production. Employees who keep their workstations tidy maintain an overview, have access to the right tools at all times and can work on the product efficiently and with quality assurance.

Information visit to TRAMAG by the VDI District Association of Bavaria North-East

On the afternoon of St Nicholas’ Day, the TRAMAG plant in Fürth hosted an information event for members of the Association of German Engineers (VDI) from the Bavarian North-East District Association. Due to the regional proximity and also taking TRAMAG’s 100th anniversary as an occasion, we received a request from the Nuremberg VDI local group to visit our plant, which we were very happy to fulfil.

“Quality is when the Customer comes back and not the Product”

The most technically innovative or economically attractive product in an application is worth nothing if the quality is not right. Not only would the failure of the product itself have to be lamented, but possibly also further damage to the entire application.
