Military Power Distribution Unit – PDU336

Military Power Distribution Unit – PDU336 is designed to manage and distribute AC and DC electrical power within military platforms. The unit receives power from multiple sources and directs it to vehicle systems with varying voltage and current requirements. By ensuring controlled distribution and electrical protection, PDU336 supports continuous and reliable operation of mission-critical equipment during military operations.

PDU336 is used in military vehicles, mobile systems, and military facilities requiring reliable onboard power distribution. Typical deployment environments include land vehicles, naval platforms, mobile command units, forward operating bases, and temporary military camps. The unit is engineered to operate under harsh environmental conditions and resist electromagnetic interference encountered in military environments.

PDU336 supports multiple power inputs including generator supply, external power supply, PTO alternator, system batteries, vehicle batteries, and DC power sources. Power is distributed through fuse-protected outputs to vehicle systems, ensuring electrical safety and load balancing.

The unit integrates manual and monitored control elements including power source selection, battery selection, emergency stop, test and status indication interfaces, and electrical measurement points for both AC and DC lines. Panel-mounted meters provide voltage, current, frequency, and operational time monitoring to support system diagnostics and maintenance.

Military Power Distribution Unit – PDU336 uses SAE J-1939 CAN protocol for communication with the vehicle Electrical Control Unit at 250 kbit/s. Status messages are transmitted cyclically every 100 ms, and command messages are expected at the same interval. If command messages are not received for 400 ms, an emergency output is asserted while the unit remains operational to allow system-level control by the ECU.

RS422 communication is used for one-way transmission of diagnostic and status data to recording or monitoring systems, providing redundancy to CAN-based monitoring.

Military Power Distribution Unit – PDU336 is designed and tested in accordance with the following standards:

• MIL-STD-1399

• MIL-STD-704

• MIL-STD-1275

• MIL-STD-810

• MIL-STD-461

• MIL-STD-901

These standards validate environmental durability, electromagnetic compatibility, vehicle and aircraft power compliance, and mechanical shock resistance.

PDU336 manages and distributes electrical power to multiple onboard systems within military platforms, ensuring stable voltage delivery, electrical protection, and operational continuity. The unit conditions incoming power, protects downstream equipment, and supports reliable operation of communication, control, and support systems under demanding military conditions.

Designed and manufactured by Nero Endustries, PDU336 provides a robust and integrated power distribution solution tailored for complex military electrical architectures.
