dU/dt filters for today’s drive and automation technology

TRAMAG products explained

dU/dt filters belong to the group of output filters, as they are used directly at the inverter output, upstream of the connected drive units – developed precisely to fit the individual drives system.

Due to increasingly efficient, fast-switching power semiconductors in the inverters, motor windings are additionally loaded. With a high-quality dU/dt filter from TRAMAG, these interference pulses and voltage peaks generated by the inverters are significantely dampened.

This is achieved by the low-pass effect of the LC combination (choke plus capacitors) of the dU/dt filter, designed above the clock frequency of the inverter.

Downstream motors are thus subjected to a reduced voltage load, which has a positive effect on the service life and availability of the motor operation.

TRAMAG has been an experienced manufacturer of filters and other winding goods for almost 100 years and convinces customers from a wide range of industries with its technical expertise.

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.
