Power Distribution Unit
The Power Distribution Unit (PDU) is an electronic pressure vessel for distribution of electrical power and ethernet signals.
The Power Distribution Unit (PDU) is an electronic pressure vessel for distribution of electrical power and ethernet signals. The set of subsea connectors allows for 2 power inputs to be distributed to 6 different outputs.
The unit contains an ethernet switch for distribution of ethernet signals, and sensors for monitoring of temperature and leak detection. PDU is nitrogen-filled and hyperbaric tested to working pressure prior to delivery.
