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.

Happy with product - good value and prompt delivery
Great customer service and competitive prices.
Beaver Easy Fin Spring Straps Quick Release Medium
Great company, fast email communication, and very quick delivery.
I was looking for a new wetsuit and found these guys online. They had the wetsuit I was after and there was a link to an interactive sizing guide to help me identify the right size. After ordering I received an email checking I had used the chart to make sure I was aware and avoid getting the wrong one. Wetsuit arrived a few days later. Cannot ask for more.
Small order, but never the less a very positive experience. My replacement fins straps were not delivered (Christmas time order) when I chased this with Russell, his email reply was instant and positive. A new order was dispatched and received a few days later. Highly recommended
