12–56V 3A Boost Step-Up Converter
📝 12 to 56 Volt Boost Step-Up Converter 3 Amp
Upgrade your 12V system with this 12–56V Boost Step-Up Converter, designed to power higher-voltage devices from a standard 12V battery bank. Perfect for campervans, RVs, 4WDs, caravans, and off-grid setups, it’s also an ideal partner for powering Starlink Gen 3 from DC power, delivering clean and stable 56V output on the move.
⭐ Essential Benefits
• Step up 12V to a stable 56V output for high-voltage devices
• High efficiency (up to 94%) to minimise power loss and heat
• Fully sealed IP68 body – dustproof and waterproof for harsh environments
• Built-in overload, over-voltage and short-circuit protection
• Compact footprint for tight installs in vans, canopies, and electronics bays
• Handles up to 168W (56V @ 3A) – great for networking gear, comms and control hardware
⚙️ Functionality
This boost converter takes a 12V DC input and steps it up to a regulated 56V DC output, ideal where your system runs on 12V but your device (such as Starlink Gen 3 or other 56V gear) needs higher voltage.
It continuously monitors load and input conditions, maintaining stable output while built-in electronic protections guard against overload, over-voltage and short circuits. The integrated heatsink and cooling design help it run reliably under continuous use, even in warm climates.
🔌 Compatibility
• Input: 12V DC battery systems (starter or house batteries)
• Output: 56V DC devices up to 3A / 168W
• Ideal for:
• Campervans, caravans, RVs, motorhomes & 4WD canopies
