Military Power Distribution Unit – PDU70
PDU70 / HIGH-VOLTAGE POWER DISTRIBUTION Military Power Distribution Unit – PDU70
Military Power Distribution Unit – PDU70 is a compact intelligent power-management unit developed for electric and hybrid military platforms. It receives high-voltage AC or DC power from primary sources and distributes it to multiple vehicle subsystems while integrating monitoring, protection and communication functions for mission-critical electrical architectures.
High-voltage distribution, monitoring and protection architecture for electric and hybrid military vehicle systems.
Controlled High-Voltage Distribution for Military Electrical Architectures
The Military Power Distribution Unit – PDU70 manages electrical power within electric and hybrid military platforms. High-voltage AC or DC power received from primary sources is routed to multiple subsystems with different electrical requirements through a controlled distribution architecture.
Integrated monitoring and protection functions support controlled energy flow and electrical-system integrity under demanding military operating conditions.
Power Management Across Electric and Hybrid Military Platforms
PDU70 is intended for medium and heavy-duty electric and hybrid military vehicles and for military systems requiring high-voltage power distribution and energy control. Supplied deployment examples include ground vehicles, naval platforms, support vehicles, mobile systems and military installations.
The described architecture is intended for land, sea and mobile environments where electrical equipment may be exposed to vibration, temperature variation and electromagnetic interference.
