• Complete portfolio of power converters from a single source 
  •  Designed for continuous operation
  •  Developed for use in mobile machines 

We offer a series of power converters in our powerMELA portfolio for the conversion of the DC intermediate circuit voltage into the type of current and the voltage level required by the consumer. powerMELA.dcdc are available for the supply of the on-board network, which transform the DC high voltage to 12 V / 24V / 48V depending on the vehicle. The powerMELA.dcdc can be parameterized via the CAN bus. 
The inverters convert the DC intermediate circuit voltage into AC voltage, and have been designed for the control of generators as well as of main and auxiliary drives. The inverters are designed for four quadrant operation and can be controlled via CAN bus with nominal values for controlling the torque, voltage and speed. The inverters are available in two different variants. The first variant is required to control a 6-phase motor with a power of up to 160 kW, and the second for the control of two independent 3-phase motors with a power of up to 80 kW each.

While we are proud of our products and solutions, it is through our customers’ applications that the power in the innovative technology is unleashed.  Whether fully networked, highly automated, or operating fully autonomously, an effective mobile machine represents first class interdisciplinary engineering. Robust and safe integration into the system architecture of the machine and its work processes, while remaining convenient and user friendly, is the main focus. With thanks to our customers, here we would like to present a small selection of example applications.



We support our customers as a partner for the digitization and automation of mobile machines and the related work processes. Our comprehensive and highly interoperable STW modular system of high quality sensing, control and software products ensures a problem free integration in the final application.


As experts in all aspects of functional safety, we offer services in high level automation in the field of mobile machines, including autonomous functions and driving. Our STW ecosystem includes a comprehensive partner network of system integrators and distributors to ensure an optimal solution for every application, worldwide.


We accompany our customers from the start whenever the E/E system in mobile machines is concerned. For this purpose, we develop solutions to support the entire machine lifecycle. We offer our competence, our services, our products and the associated tools in the individual phases in order to make an efficient and continuous contribution towards the success of the machine. 



The STW "ECO System" is characterized through the integration of systems and products which transcend the borders between solution areas. Our partners also supplement the STW product and services portfolio for the benefit of our customers. The open nature of the product portfolio permits easy integration of the products into third-party systems or the supplementation of our system through further products by third party providers.
