Key highlights
The PDU-P4 is an 8-channel power distribution unit in a rugged, compact and modular enclosure. The unit includes four output connectors, each equipped with two power lines and redundant CAN. With this, each of the four output connectors can be utilized for multiple purposes:
Supplying two individual loads from one output connector
Paralleling the power lines to achieve higher power capability to a load
Supplying a load with a fully redundant set of power lines
The PDU-P4 architecture allows designers to allocate one subsystem per power channel, whereby many of the EMI issues experienced on shared power buses are eliminated. This makes the PDU-P4 ideal for missions with demanding payloads and sensitive receivers.
All outputs have independent power monitoring and latch-up protection. Monitoring and configuration is enabled through the CSP protocol and onboard redundant MCUs.
