BEP Marine - 710-140A Digital Voltage Sensing Relay - 140 Amp

Intelligent Battery Management for Marine Applications

The BEP Marine 710-140A Voltage Sensing Relay (VSR) is an advanced solution for efficiently managing battery charging in marine environments. Designed to safely charge multiple independent battery banks from a single source, this device ensures that your engine start battery remains fully charged while seamlessly managing auxiliary battery power. With digital circuitry for enhanced reliability and extremely low power consumption, this VSR is an essential component for any marine electrical system.

Advanced Digital Voltage Sensing Technology

The BEP Marine 710-140A DVSR automatically engages when the voltage of a charged battery bank reaches the necessary level, allowing a second battery bank to charge. Once charging stops and voltage drops, the relay isolates the battery banks to prevent depletion of the starting battery. The integration of digital enhancements, including remote sensing circuitry, allows for added control with zero power draw when the engine is off.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
