BEP Marine

<h3>About BEP Marine</h3><p><strong>BEP Marine</strong> has been a cornerstone of the marine electrical industry since its founding in 1995 in Auckland, New Zealand. Rooted in New Zealand's world-class yachting culture — a scene shaped in no small part by successive America's Cup campaigns — BEP Marine built its reputation on engineering electrical products that could survive the most demanding conditions on the water and beyond. Today, the brand is part of the Navico Group under Brunswick Corporation, and its products are specified as original equipment by leading boat, emergency vehicle, and RV manufacturers worldwide.</p><h3>Engineering for the Harshest Environments</h3><p>What separates BEP Marine from generic electrical suppliers is a relentless focus on real-world performance. Every product in the BEP lineup is designed to meet exacting performance specifications, capable of withstanding prolonged exposure to salt air, moisture, vibration, and extreme temperatures — both at sea and on land. BEP backs this confidence with a &quot;Trusted Quality&quot; 5-year warranty across their product range, a testament to how thoroughly their components are tested before they reach your vessel.</p><p>BEP's engineering culture also prioritizes ease of integration. Whether you're wiring a simple single-battery sailboat or a complex multi-bank power system on a large cruiser, BEP products are designed to slot into both straightforward and comprehensive electrical architectures without hassle. Their innovative product lines — including the CZone digital switching system and the Pro Installer series — represent the cutting edge of onboard power management, allowing boaters to monitor and control circuits from touchscreen interfaces and minimizing valuable space in crowded electrical panels.</p><h3>Core Product Categories</h3><p>BEP Marine's catalog spans the full spectrum of marine power management. At the heart of their offering are <a href="/11486-bep-marine-battery-switch-12204">battery switches</a>, where BEP has pioneered design innovations for decades — from compact On/Off isolation switches to high-capacity selector switches rated at 400A continuous and 600A intermittent. Their award-winning EZ-Mount line (recipient of the prestigious METS DAME award) features an industry-standard footprint that clusters with other Pro Installer components, saving precious onboard space.</p><p>For remote power control and automated charging management, BEP's <a href="/11486-bep-marine-solenoids-202547">solenoids</a> allow boaters to switch high-amperage loads using low-current control circuits — essential for bow thrusters, windlasses, and other high-draw accessories. The Digital Voltage Sensing Relay (DVSR) automates second battery bank charging with exceptional efficiency.</p><p>Rounding out the core lineup, BEP's <a href="/11486-bep-marine-battery-disconnect-switches-200143">battery disconnect switches</a> deliver reliable isolation capability for single or dual battery banks, ensuring your vessel's electrical system can be safely de-energized for maintenance, storage, or emergency situations. Motorized disconnect variants allow remote operation, making them ideal for installations where the battery is difficult to access directly.</p><h3>Who Uses BEP Marine?</h3><p>BEP Marine serves both OEM boat builders and the marine aftermarket, with a product range trusted by recreational boaters, commercial operators, and emergency vehicle fleets across North America, Europe, Asia Pacific, and Oceania. If your application demands reliable, durable, and intelligently designed electrical components, BEP Marine delivers solutions built to go the distance.</p>

Product Details

The BEP Marine 701-MDVS-D is a 275A continuous-rated motorized Voltage Sensitive Switch (VSS) designed to automatically manage dual battery bank charging and emergency parallel connection in marine applications. This intelligent switch monitors both battery banks and combines or isolates them based on charging source presence, ensuring optimal battery management without manual intervention.

Automatic Voltage Sensing Operation:

The VSS engages when either the start or house battery reaches 13.7 volts, combining both banks for efficient charging from an alternator or shore power charger. With integrated engine run sensing, the switch intelligently manages battery isolation: if combined voltage drops below 13.0 volts with the engine off, contacts open after 5 seconds. When the engine is running and voltage drops below 12.2 volts, the switch remains engaged for 5 minutes before opening, preventing premature disconnection during high electrical loads.

Remote Emergency Parallel Function:

The 701-MDVS-D can be activated via a momentary dash-mounted button to parallel both battery banks for emergency starting. The emergency parallel mode runs for a preset 10 minutes, after which the switch automatically determines whether to stay engaged based on voltage levels or return to normal VSS operation.

Key Features:

  • Dual battery bank sensing with automatic combine/isolate functionality
  • Deutsch connector for reliable marine connections
  • Manual override option for emergency parallel operation
  • Engine run sensing prevents unnecessary battery drain
  • Marine-grade construction with tinned copper conductors and stainless steel hardware
  • High-temperature, fiber-reinforced plastic housing for durability
  • Ignition protected design for safety
  • Recessed or surface mounting options

Technical Specifications:

  • Continuous Rating: 275 Amps DC
  • Intermittent Rating: 455 Amps DC
  • Cranking Rating: 1,250 Amps DC
  • Voltage Rating: 9.5 - 32 Volts DC
  • Stud Size: 2 x 10mm (3/8-inch)
  • Power Draw: 12mA (off), 15mA (on), 120mA during switching operation (3 seconds at 12V nominal)
  • Operation: On/Off with automatic voltage sensing

Ideal for boats with dual battery systems requiring automatic charging management and emergency parallel capability in a single, reliable unit. The VSS eliminates the need for manual battery switch management while providing peace of mind with emergency backup functionality.

Fast service.

It is the best

I couldn&#039;t view the delivery date

Good price and timely delivery!

Easy site to use !! Now if I receive shipment in tact!!!
