This device is recommended for trucks, buses and other vehicles with a 24 volt on-board network.
Not recommended for use with batteries less than 60 Ah.
The microprocessor equalization device (MVU) is designed to equalize the charge during charging of 2 series-connected 12-volt storage batteries (accumulator batteries) into a 24-volt automobile on-board network and prevent overvoltage on one of the batteries.
Batteries of even one batch have scatter of leakage currents, charge-discharge characteristics. During operation, these differences increase. The result is a voltage imbalance between the batteries, with one battery continuously undercharging and the other overcharging, resulting in reduced battery life.
The operation of the device is as follows: as soon as a potential difference appears between the two batteries, the MVU begins to "pump" the charge from one battery to another until the same potentials are established on both batteries.
Due to the normalization of the charging process, the durability of the battery increases, especially if the batteries are of different ages, produced at different manufacturing plants, nominal capacities differ, etc.
