Step-Up Voltage Converter (12V to 48V)

⚡ Power Meets Reliability for Marine and Hybrid Systems ⚡

Transform your 12V marine electrical system into a powerful 48V backbone with our Step-Up Voltage Converter. This high-efficiency solution delivers stable 48V DC output from your existing 12V battery bank, unlocking access to modern marine electronics, communication systems, and energy-efficient appliances that operate natively on 48V power.

Designed specifically for demanding marine, hybrid, and electric vessel applications, this converter ensures dependable power delivery while maintaining excellent durability in the harshest saltwater environments. Whether you're upgrading your boat's electrical infrastructure, integrating renewable energy systems, or powering mission-critical equipment, this non-isolated converter delivers the reliability and performance you need.

Why 48V Systems

48V is rapidly becoming the new standard for hybrid and electric boats, modern battery packs, and solar systems. This voltage offers significant advantages: reduced cable size requirements, lower current draw, improved efficiency over long runs, and compatibility with the latest marine electronics. However, many boats still rely on 12V battery banks. Our step-up converter bridges this gap, allowing you to harness 48V benefits without completely rewiring your vessel.

Key Features That Set Us Apart

  • 🌊 IP68 Waterproof Protection: Completely sealed against water immersion and dust ingress. This isn't just splash-resistant – it's engineered for continuous operation in wet engine compartments and can handle temporary submersion.
  • ⚙️ Wide Input Voltage Range: Operates reliably between 10V-16V DC, accommodating voltage variations in your 12V system during charging cycles, engine operation, and battery discharge states.
  • 🔋 Rock-Solid Output Stability: Delivers consistent 48V DC output regardless of input fluctuations, protecting sensitive electronics and ensuring optimal performance of connected devices.
  • 💡 Industry-Leading 93% Efficiency: Minimizes power loss and heat generation, crucial for space-constrained marine installations where every watt counts.
  • 🔥 Comprehensive Protection Systems: Built-in overload, overheat, and overvoltage protection safeguards both the converter and your connected equipment, ensuring long-term reliability.
  • 🏗️ Marine-Grade Construction: Aluminum housing provides excellent heat dissipation and corrosion resistance, while compact dimensions fit into tight installation spaces.

Technical Excellence

Marine-Grade Durability

The IP68 certification means this converter can handle the marine environment's unique challenges. Salt spray, humidity, temperature variations, and vibration are no match for its robust aluminum construction and sealed design.

Installation Simplicity

Straightforward wiring with color-coded connections:

  • 🔴 Red: Positive input (connect to 12V positive)
  • Black: Negative input (connect to 12V negative/ground)
  • Black: Negative output (48V negative)
  • 🟡 Yellow: Positive output (48V positive)

Operating Specifications

Both models operate reliably in temperatures from -20°C to 80°C, covering everything from Arctic expeditions to tropical cruising. The wide operating temperature range ensures consistent performance regardless of climate conditions.

💡 Important Considerations

  1. This is a step-up voltage converter, not a battery charger. It's designed to boost your 12V system to 48V for powering equipment, not for charging 48V battery banks. For battery charging applications, contact us about our DC-to-DC charger solutions.
  2. Always verify that your connected devices are compatible with 48V DC input before installation. Most modern marine electronics specify their voltage requirements clearly in their documentation.

Why Choose Our Step-Up Converter?

In today's marine environment, electrical systems must be reliable, efficient, and adaptable. Our step-up converter provides the bridge between traditional 12V boat electrical systems and the growing ecosystem of 48V marine electronics. With proven reliability in harsh marine conditions and the flexibility to power diverse equipment types, it's an essential component for any modern vessel.

Whether you're upgrading communication systems, improving energy efficiency, or adding new capabilities to your boat, this converter opens up possibilities that weren't available with 12V-only systems. The combination of high efficiency, robust protection, and marine-grade construction makes it a sound investment in your vessel's electrical infrastructure.
