Runko PDU datasheet coming soon!
The datasheet will include key electrical, mechanical and environmental specifications for the PDU (ratings, fuse options, dimensions, interfaces and operating limits). It will also cover integration and safety information such as HVIL/IMD options, grounding, applicable standards and ordering details.
Built for prototypes and small-series builds
Hard-to-source HV connector combinations add cost and lead time, because different connector brands often require different tooling and sourcing. By standardizing HV connectors, you keep cable-gland HV cabling agile and repeatable from prototype to small series.
RUNKO PDU is built to keep that part simple,
Easy-to-source HV connectors, only one end needs to match the device, other end flying lead
Using standard cable lugs
Scalable fuse positions for multiple HV loads (sizes S, M, and L)
Add outputs as requirements evolve
Access-friendly design for faster commissioning and troubleshooting
Centralized HV Distribution (PDU) Benefits
-
Clean HV architecture: centralized two sided distribution and fusing reduces cabling complexity
-
Service-friendly layout: protection and service access in one place for faster troubleshooting
-
Integration-ready packaging: clear interfaces that are easier to document and maintain
-
Safety-ready interfaces: supports interlock/HVIL integration as part of operation and service design
-
Scalable outputs: Size-dependent fuse positions for multiple HV loads
When will Hevtec’s Runko PDU be available, and what sizes will it come in?
Runko PDU product series has been finalized in three sizes: S, M and L. First prototypes will be piloted together with the Koski MCS interface in early 2026.
Why is the PDU a critical part of NRMM electrification integration?
A PDU is the machine’s high-voltage “power hub.” It connects the battery and electric components, distributes power to loads, and protects the system with built-in safety and protection functions—making the HV architecture clearer, safer, and easier to service.
How does a PDU improve integration and serviceability in electrified heavy machines?
A PDU centralizes high-voltage distribution and fusing into one clear unit. This reduces wiring complexity, makes interfaces easier to service, and speeds up commissioning and troubleshooting.
How do I size the fuses?
Fuse sizing depends on ambient conditions, load profile, and component limits. Don’t worry — our team can help you size and validate the protection correctly.
Electrification rarely fails on a component. It fails on integration. If you’re unsure about HV distribution, fusing or interfaces, let’s review your system and integration plan. Book a technical consultation.
