The Mastervolt Magic is a DC-DC charger which is designed to provide quick and safe charge to the service battery, providing stabilised voltage, even when the battery voltage fluctuates, to protect the battery and the equipment it powers. It provides galvanic isolation between the input and output to prevents disruptions to communication devices and other appliances.
Traditionally, a service battery is linked to the starter battery via a charge relay. The starter battery will be located near to the alternator and receives most of the charge current. However the service battery is usually further away. The long cables used to connect it up cause a voltage drop, leading to slower charging, which can result in failing appliances and premature failure of the battery.
Modern, fuel efficient engines are equipped with smart alternators, following regulations such as Euro 5 and Euro 6. Instead of a constant output, smart alternators provide a variable voltage; after a brief charging period, voltage is reduced and the charging stops. Furthermore, the energy produced by regenerative braking leads to voltage peaks. Service batteries coupled in the traditional way will receive hardly any charge and may be damaged by these peak voltages.
To solve these issues, Mastervolt offers the Magic DC-DC chargers, which monitors the service battery and compensates the voltage loss. It is suitable for flooded, Gel, AGM, spiral, Li-Ion and traction batteries. These units feature an energy saving dimmer function, where energy is not wasted in heat form, but instead the power supply is regulated to prevent issue. The Magic converters can be programmed via PC, using the communication port, and they can also be used in parallel to achieve higher charging capacities. The Magic is also MasterBus compatible, so can be monitored and included in an intelligent automated system.
