SubConn technical reference
The figures below describe the referenced SubConn configurations, not verified DepthLink alternatives. Final supplied specifications and mating compatibility are confirmed with your quotation. Qualified pressure-test values are shown as published and are not automatically working-depth ratings.
Technical information reviewed 19 September 2026Single contact1 kV / 250 A or 3 kV / 90 A
Battery600 V; 25 A/contact; 50 A total
High power600 V; 50 A/contact in water
High-power total200 A across four contacts
Typical applications
- ROV and subsea machinery power
- Battery charging
- Underwater pumps
Selection notes
The 1 kV and 3 kV versions have different current limits and termination formats. The source recommends insulating oil around the 3 kV bulkhead; agree installation details with the manufacturer.
