These chargers are made in a modern design and are equipped with smart dynamo according to Euro 5 and Euro 6 rules. These alternators are intelligent in shape and offer a variable voltage instead of a constant output. Therefore, after a short charge, the voltage decreases and then it stops charging. Note that this device, in addition to the energy produced by the regenerative brake, leads to voltage peaks in the Marinland Dubai and Sharjah. Traditionally connected service batteries are difficult to charge and may be damaged by these peak voltages. In the following, to solve problems such as damage and injury, we will introduce you to the mac plus series, which is available in 12 volts or 24 volts. Mac Plus monitors service battery and compensates for voltage drop. Proven 3-step charging method ensures fast and safe charging. In addition, the MacPlus protects your service battery and sensitive equipment by stabilizing the charging voltage. So you should know that in boats and ships, the battery can be drained quickly and it will take time to recharge the battery, so MacPlus will solve your problem.
