WE CONNECT THE E-POWERTRAIN
High-voltage power distribution units for electric drives and additional high-voltage consumers
Manufacturing and development of HV PDUs
High-voltage distribution unit safely distributes high currents
in-Tec Bensheim develops and produces individual high-voltage power distribution units (PDUs) for the vehicle sector. We develop prototypes and take on the series production of your individual high-voltage power distribution unit. Trust in our expertise.
Producer for PDUs
As with the production of other components for the HV on-board network (On-board fuse box) we also offer you flexible solutions here. We take over the complete development of the HV-PDU for your application or produce according to your specifications. We take care of the selection of the components and the procurement of materials.
The components available on the market allow the production of PDUs for voltages up to 500 V DC. We develop power distributors for higher voltages as special solutions.

Our services for high-voltage PDUs
Your individual PDU for the automotive sector - the production of the power distributors is in the best of hands with us. Our partner company, the in-Tec Project & Competence Center, takes over the complete development of PDUs or fuse boxes for your company's own or required application, if required.
Efficient series production of HV PDUs: industrialising PDUs safely
We support your PDU project from the initial requirements through to a solution ready for series production. Depending on the project, we either take full responsibility for developing your power distribution unit or manufacture it based on your specifications. Even in the early stages, we assist with selecting suitable components, designing the enclosure, protection and interfaces, and planning robust cabling.
Step by step, initial concepts and prototypes evolve into an HV PDU that not only proves itself technically, but can also be manufactured economically and reproducibly at scale. We handle material procurement, inventory management and the transition into stable production processes, as well as the complete implementation of your cabling solution in both high- and low-voltage systems.
Typical project workflow:
- development according to customer specifications or full co-development
- design of components, enclosure and interfaces
- prototype and pre-series production
- transition to robust series production processes
- material procurement and inventory management
- tested and delivered ready for installation
Applications in the automotive and e-mobility sector
- Electrification of construction and agricultural machinery (off-highway)
- Transport vehicles (buses)
- Special machines
- Municipal vehicles
- Electric boats, ships and tugs
- Any electric or hybrid vehicle in which high voltages need to be safely distributed
High-voltage plug connections ensure flexibility
We can equip your PDUs with HV connector systems. A load or inverter can easily be separated from the unit for maintenance or replacement. It is therefore not necessary to open the PDU and the tightness is guaranteed.
MultiPower series as a plug-and-play solution
Looking for a faster alternative to fully customised development? With our MultiPower series, we offer ready-to-operate plug-and-play HV PDUs for a wide range of requirements – from compact, all-round solutions to high-performance versions for construction and specialised applications.
HV PDUs for ePTOs and additional electrical loads
Where electrical power in a vehicle is supplied not only for the drive system but also for other electrical loads, a well-designed distribution system is essential. Our HV PDUs are designed precisely for this purpose – including in ePTO-related applications for superstructures, auxiliary units, and trailer concepts. In this way, we create the technical foundation for additional electrical functions in commercial vehicles.
Your questions - our answers
What is a Power Distribution Unit (PDU)?
A PDU is used to distribute currents and voltages in the power grid. In this case it is a " high-voltage power distributor ". In the field of e-mobility, the PDU gets its power from one or more batteries. Depending on the type of load, the individual outputs are protected against overvoltage with fuses.

In the field of e-mobility, the PDU gets its power from one or more batteries. Depending on the type of load, the individual outputs are protected against overvoltage with fuses.
The distribution of the currents is active or passive. With passive distribution, the output lines are connected in parallel, whereas with active distribution contactors control the distribution to the outputs.
Contactors are electromechanical switches. The switch is opened or closed by using an excitation voltage and a built-in coil. Contactors can be used to switch both DC and AC voltages with high currents.

What is the use of an active discharge system in the PDU?
In the event that a load is disconnected from the PDU, the line must be discharged within 60 seconds - to less than 60 V for direct current (DC) and to less than 48 V for alternating current (AC). Many loads or inverters support active discharging from the start. If this is not the case, an active discharge system can be integrated into the PDU for the respective output.
What is the benefit of a voltage converter in the PDU?
By installing voltage transformers in the Power Distribution Unit, it is also possible to supply other power networks in the low-voltage range, such as the vehicle electrical system.
