The transport and traffic system is in constant change

We, inpotron Schaltnetzteile GmbH, have been supporting our customers in the implementation of projects in the mobility sector for years. Our products are used both in rail vehicles, heavy goods vehicles and in infrastructure.

Due to strict standard requirements, such as those of EN 50155, our power supplies are becoming increasingly important. High reliability combined with long product availability are always decision criteria for our customers.

Mechanical loads as well as requirements for parallel and redundant operation are taken into account in the development of our products, which are specially tailored to your needs.

Convection cooling without derating up to an ambient temperature of 70°C, but also operation from -40°C are successfully implemented by our development team. To this end, our solutions are subjected to extensive environmental tests, monitored by our specialists for standards and approvals.

We build DC/DC converters for the most common battery supply voltages exactly to your specifications. Our teams at 3 locations throughout Germany are working to implement your customer requirements perfectly.



During the development of our customer-specific power supplies, the following requirements, among others, are taken into account:

  • Input and output voltage range according to specification (AC/DC, DC/DC, wide range, battery voltages)
  • Conformity to standards EN50121, EN50124, EN50125, EN50155, EN50163
  • Resistance to vibration and shaking according to DIN EN 61373
  • Safe against mechanical shock according to ISO 16750-3
  • Smart coating with 3M Novec EGC-1700 to increase mechanical strength and resistance to environmental influences


The following principles apply to all our power supply solutions

  • RoHS and REACH compliant
  • Contact or convection cooled solutions for maximum running time
  • For high temperature requirements (-40°C to + 70°C without derating possible)
  • Long service life and reliability through optimal design, high-quality components and in-house production in Germany
  • 100% quality inspection
  • Ensuring conformity to standards through in-house specialists
