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.

Does the job
Size: 53" x 48", Style: Starter Wall
Decent look, basic unit. Wasn’t the easiest build, I had to trim panels to get a good fit. Great price, but quality matches that point.

Great socks, watch out for bad seller
Number of Items: 6, Color: Black (6-pairs), Size: Medium
The socks are great, comfy, padded where you want it. I used these for work socks; I have a blend of corporate desk life and maintenance work. I like the low cut so my shoes don't rub the back of my ankle but not so high that socks always fall down. Great for running and sports as well. Been using these for years. Buyer beware though of the particular seller Liegnitz Group: They were late shipping, sent me the wrong socks so I sent for a return and they send me the right ones. My return got delivered back to them but they did not process it and did not send out any new ones. They cancelled my order and acted like I got the right ones all along. Buy from a different retailer.

Comfortable with perfect fit
Number of Items: 6, Color: White (6-pairs), Size: Medium
I have had these socks for a few weeks now and wear them when running. I have small feet at a men's size 7 and they fit perfectly. Most men's socks are to big for my feet. They are pretty thin but well made and have good cushion. I recommend these for anyone that likes ankle socks for athletic activities.
