Description

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.

Key features

  • 2 power inputs, 6 outputs
  • Temperature and leak detection sensors
  • Designed for 3000 m water depth
