Samlex Step-Up DC-DC Converter - 10A - 9-18V Input - 24V Output

The Samlex Step-Up DC-DC Converter (Model STEP10) is a 10-amp switch-mode power converter designed to reliably step up 12VDC battery voltage to 24VDC output, making it essential for marine vessels requiring dual voltage systems. This converter accepts input ranging from 9–18VDC, providing stable 24-volt supply at 10 amps continuous capacity—ideal for powering modern marine electronics, navigation systems, and auxiliary equipment from a standard 12-volt house or starting battery.

Built with CE-approved switch-mode technology, the STEP10 delivers high conversion efficiency while minimizing heat generation and power loss—critical on long offshore runs where battery reserve matters. The unit features comprehensive protection circuits: over-current protection to safeguard connected equipment, over-voltage protection against electrical spikes, and reverse-polarity protection to prevent catastrophic damage if wiring is accidentally reversed during installation. Standard 6.3mm push-on flat-pin connectors ensure compatibility with common marine electrical terminals. Compact dimensions (4 × 2 × 5 inches) and lightweight construction (0.9 lbs) allow flexible mounting in engine compartments or below-deck spaces where space is limited.

Weekend anglers and serious offshore fishermen alike benefit from this converter when upgrading older vessels to modern 24-volt systems or running mixed-voltage fleets. Charter operators and commercial fishing vessels often employ multiple STEP10 units to power independent 24-volt subsystems—radar, autopilot, or auxiliary hydraulic pumps—without a complete electrical overhaul. Marine electricians specify Samlex converters for their reliability in salt-air environments and proven track record in retrofit installations where cost-effective voltage conversion is needed.
