Mastervolt MasterShunt 500 ANL-Class T Fuse Capable 
MasterShunt 500 ANL/Class T Fuse Capable
MasterShunt is the heart of every MasterBus energy system. This integrated battery monitor shares information about the battery bank with other Mastervolt devices such as battery chargers, Combis, and displays. No surprises: allowing complete automation of your system, MasterShunt improves comfort, prolongs battery life and extends your runtime.
The MasterShunt 500 provides all information needed for monitoring your battery bank and control of your system, such as voltage, current, state of charge and time remaining. All information is made available to the system by a single MasterBus cable.
Extremely accurate measurement of current flow over state of charge enables the MasterShunt to precisely determine the time remaining. Programmable events and an integrated real time clock make it possible to fully automate your system. Examples are to start your generator automatically when the battery bank is low or to automatically generate a warning at a certain depth of discharge.
The proven MasterShunt design has been upgraded to obtain an even higher level of accuracy and control. A new service mode prevents loss of valuable information, such as the state of charge, during system maintenance. A maximum Depth of Discharge (DOD) can be set and time remaining will be adjusted accordingly. Taking into account battery specific parameters, MasterShunt takes reading accuracy to a whole new level.
The renewed MasterShunt allows freedom of choice with regards to fuse type, rating and location. The battery monitor is supplied with an internal bus bar, to be used in situations where an external fuse holder is selected. In case the MasterShunt is installed close to the battery, the bus bar may be replaced by either an ANL type or Class T main fuse, saving both space and cost.
