Subsea Power Supply

  • Subsea Power Supply

    Product Overview

    Have 120 V AC, but need 24 V DC? Our standard subsea power supplies take a Universal type AC input voltage of 85 V to 264 V single phase AC and converts it to 24 V DC. The power supplies are good for 500 W of power and 21 A of current; if higher power is required the units can be parallel connected.

    The power supplies feature remote monitoring and control and an onboard display that can be used for technician or camera feedback. Additional features include RS-232 and RS-485 data interfaces, Chasses Isolation Monitoring, Modbus control, and an ambient light sensor that can be used for providing feedback to Remotely Operated Underwater Vehicles (ROVs).

    The units can be operated in air or in a pressure-balanced oil-filled (PBOF) configuration.

    2G Engineering is an AS9100 certified organization.

    Testing & Verification

    Each unit sold undergoes a rigorous factory acceptance test before it leaves our facility. A copy of the test records are included with each unit.

    If a customer has specific requirements for testing please contact us and we will be happy to adapt our procedures to meet your requirements.

    Product Configurations

    All units feature standard MODBUS command protocol support for remote monitoring and control.

    The power supplies also feature a real time software programmable output voltage control between 22 V to 26 V DC. This allows a customer to compensate for line losses in their system at high loads.

    Three-phase input versions are available upon request. Please contact 2G Engineering for any other project specific requirements.
