Stable DC power, wherever the load lives.

Marius-DC is a rugged step-down (buck) DC-DC converter family for subsea and remote systems. It turns a wide, noisy input bus into stable regulated output for your electronics — built for high efficiency, reliability, and long unattended operation in harsh environments.

  • Wide input rangeAccepts a broad, variable DC bus and holds a steady regulated output.
  • Configurable outputsRegulated 12 V / 24 V / 48 V rails to match your system.
  • High efficiencyLow-loss conversion preserves energy on long deployments.
  • Full protectionOver-voltage, over-current, and thermal protection built in.
  • Wide temperature rangeEngineered for the temperature extremes of subsea and remote sites.
  • Rugged enclosureSealed Aluminium or Titanium housings; optional RS-485 monitoring.
