Production of High-Voltage Power Distribution Units for E-Mobility
in-Tec Bensheim develops and produces individual Power Distribution Units (PDUs) in the high-voltage range for your application.
Safe Distribution of High Currents.
in-Tec Bensheim is a specialist when it comes to cabling in the high-voltage sector. We develop prototypes and assume responsibility for the serial production of your individual high-voltage power distribution unit. You can rely on our expertise.
As with all of our products and services, we offer you flexible solutions. We assume responsibility for the complete development of the HV-PDU for your application or produce according to your specifications. In doing so, we take care of the selection of 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.

What is a Power Distribution Unit (PDU)?
A PDU is used to distribute currents and voltages in the power grid. Therefore, in this case, it is a "high-voltage power distributor". In e-mobility, the PDU receives 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.
High-Voltage Connectors Provide Flexibility
The PDUs can be equipped with HV connector systems. As such, a load or inverter can be easily disconnected from the unit for maintenance or replacement. For this reason, it is not necessary to open the PDU, and the tightness is guaranteed.
Active Discharge
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.
Supply in the Low-Voltage Range
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.
