The Mastervolt DC Master is a DC-DC charger which is designed to provide quick and safe charge to the service battery, providing stabilised voltage to protect the battery and the equipment it powers. This is a non isolated model which has an electrical connection between the input and the output, making it suitable to applications with negative earthing. It is also compact and efficient, with low heat generation.

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 DC Master chargers, which monitors the service battery and compensates the voltage loss. There is no fan so operation of the charger is silent and these units also have 2 minutes of extra capacity, perfect for if you need a quick power boost. The DC Master unit is supplied complete with mounting bracket, screws and fasteners.

Classic and useful.
Color: Black
I purchased to gift my son for his apartment. It is both attractive and useful. The weighted base makes it functional and balanced, and all for a very minimal price.

Budget friendly and useful!
Color: Black, Color: Black
Light weight affordable and still nice. Could be a little bit heavier at the base, I really like it so far. Seems pretty sturdy, definitely will need to check in to see the longevity of the product. Overall good budget buy.

Use for canning rings
Color: Black
I bought this to hold my canning rings and it worked great. The smaller arm holds my wide mouth rings and the larger one holds the regular ones. When I’m canning, I’m able to move the whole thing into the kitchen due to its light weight and use what I need. Once I’m done with the rings, back they go.
