Mastervolt BI 702-S Load Separator

MASTERVOLT BI 702-S Load Separator

Ensure unwavering reliability and optimal charging for your critical onboard power systems with the Mastervolt BI 702-S Load Separator. Engineered for demanding marine and mobile applications, this advanced device provides a robust solution for charging two separate battery banks from a single power source, such as an alternator or a battery charger. Its primary function is to intelligently distribute charge current while keeping the battery banks isolated, guaranteeing that the use of your service battery for accessories and appliances will never drain your essential engine starter battery. This provides invaluable peace of mind, knowing your vehicle or vessel will always be ready to start.

The BI 702-S load separator utilizes proven diode technology, a method renowned for its exceptional reliability and durability due to the absence of moving parts. This solid-state design minimizes the risk of mechanical failure, offering a dependable "fit and forget" component for your electrical system. A key advantage of the Mastervolt design is the minimal voltage drop. While standard diode separators can suffer from a significant voltage loss that leads to incomplete charging and reduced battery lifespan, the BI series is engineered for high efficiency.

To counteract the inherent voltage drop of diode technology completely, the BI 702-S features a vital connection for alternator compensation. This allows the separator to signal the alternator´s voltage regulator, prompting it to slightly increase its output voltage. The result is a full and complete charge that reaches your batteries, ensuring they are maintained at optimal health, which extends their service life and maximizes their performance. This intelligent feature makes the Mastervolt range of Separators a superior choice over conventional isolators. The BI 702-S is designed to be a compact and integral part of any professional power system, capable of handling significant charge currents while maintaining a small footprint for flexible installation.
