The latest evolution, the UNIBLOCK™ UBT+, offers up to 97% efficiency and highest reliability with state-of-the-art technology, unique design and versatile options, making it ideal for new and existing installations. While the UBTD+ diesel-coupled configuration produces the most efficient and reliable power supply possible.
Battery monitoring systems are used today to monitor each individual jar and determine if there is a bad battery for replacement before it drags down the rest of the string. They are passive devices that don’t do anything to extend battery life. The BMCS system not only monitors and identifies the cause of the problem before a failure by periodically checking the internal resistance, temperature and voltage of each individual battery it also regulates the loading charge of each battery, extending the life up to its full design life. This avoids overcharges or undercharges which results in a longer lifespan of the complete battery system. With a proper charge on each cell, problems like sulphation of plates, grid corrosion and dryout are minimized doubling the useful life of VRLA batteries. The results are significant costs savings and much less recycling of hazardous materials.
