Furuno PR240 AC to 24VDC Rectifier

Marine enthusiasts and professionals know that reliable power is the backbone of any successful voyage. The Furuno PR240 steps in as a robust AC to 24VDC rectifier, designed specifically to deliver steady, clean power to your onboard electronics. Whether you're running radar systems, chartplotters, or other Furuno gear, this unit ensures uninterrupted performance even when shore power or generator input fluctuates.

Engineered for the Demands of the Sea

Furuno's commitment to excellence shines through in the PR240, built to withstand the corrosive saltwater air, vibrations from rough seas, and temperature swings that define marine life. Unlike basic converters, this rectifier maintains a stable 24VDC output, preventing voltage drops that could cause display glitches or sensor failures during critical moments—like navigating fog or spotting fish schools.

Its bolt-on mounting makes it a seamless fit for tight engine compartments or helm stations, saving you time and hassle during setup. No wiring harness included means you can customize connections to your vessel's existing setup, promoting a cleaner, more professional installation.

Unlocking Peak Performance from Your Electronics

• Seamless Power Conversion: Transforms standard AC inputs into dependable 24VDC, ideal for powering Furuno's ecosystem of marine displays, autopilots, and communication devices.
• Rugged Durability: Proven in extreme conditions, from commercial fishing fleets to recreational yachts, ensuring your gear stays operational when it matters most.
• Effortless Integration: Bolt-on design allows quick mounting on bulkheads or panels, with straightforward wiring for DIY boaters or pros alike.
• Quality Assurance: Backed by Furuno's reputation for precision engineering, delivering years of trouble-free service.

Real-World Applications on the Water

Picture this: You're out on a multi-day charter, relying on your Furuno multifunction display for navigation. A sudden swell rocks the boat, and your generator kicks in—without a reliable rectifier like the PR240, erratic power could scramble your charts or sonar readings. This unit keeps everything humming smoothly, supporting everything from VHF radios to AIS transponders.

For upgrades, it's a game-changer when retrofitting older boats with modern 24V systems, bridging the gap between AC shore power and DC-dependent nav gear. Boaters report fewer battery drains and longer equipment life, making it a smart investment for reliability-focused setups.

Installation Insights for Smooth Setup

Getting the PR240 up and running is straightforward, but a few pro tips elevate the process:

1. Choose a dry, ventilated spot away from bilge water for optimal longevity.
2. Secure with bolts to handle engine vibrations—use marine-grade stainless hardware.
3. Match wire gauges to your load: 10-12 AWG for most setups to minimize voltage loss.
4. Test under load after install to confirm stable output, mimicking real-world use.

Always prioritize safety: Disconnect batteries and follow ABYC standards to avoid shorts.

Why It Stands Out in a Sea of Options

Generic rectifiers might seem cheaper upfront, but they often falter in humid, salty environments—leading to corrosion, overheating, or inconsistent power. The PR240's marine-specific design means better heat dissipation, IP-rated protection, and output filtering that shields sensitive electronics from noise. It's not just a power supply; it's peace of mind on the water.
