High-Voltage DC Power and Charging Solutions for Electric Equipment
CCS and MCS charging interfaces and high-power distribution units are built for demanding off-highway use. When charging, power distribution, and the powertrain are integrated as one engineered system, you get rugged reliability and integration-ready features.
Their names are inspired by Finland’s flowing nature: Puro (stream) and Koski (rapid), plus Runko (trunk), our HV power distribution unit.
RUNKO PDU
Size L
Best for centralized HV distribution and protection in electrified machines.
PURO CCS
500 kW
Best for depot and site charging where rugged CCS integration is needed.
KOSKI MCS
1000 kW
Best for: High-utilization heavy-duty use cases where downtime must stay short.
Product status update
- Puro CCS interface: launched in June 2025 (IVT Expo Köln) and first deliveries installed in customer machines.
- Koski MCS interface: piloting starts in early 2026 in a heavy duty truck in Finland.
- Runko PDU: product series specifications finalized (sizes S, M and L). First prototypes will be piloted in early spring 2026.

Your shortcut to next-generation sustainable machinery.
CCS or MCS, which should I choose?
Choose CCS for practical daily charging, including overnight. Choose MCS when daily energy demand is high and you need to recoup range within short stops during operations.
When do I need a PDU?
When you want centralized and realiable HV distribution, clear protection and a cleaner wiring architecture to speed up project lead time, commissioning and service.
