The Cristec Battery Monitor is supplied with one shunt. However, it has the facility to monitor up to two other battery banks or sources of energy. For each additional battery bank or energy source that you may wish to monitor, you need to purchase one of these kits.
The KITSHUNT is rated at 250A (this is the maximum amount of current that can be monitored with this shunt).
Note; a Cristec KITSHUNT-500A is available on request.
A current measuring shunt is the device which measures current flow in one direction or another. This is usually associated with charge flowing into or out of a battery bank, but it can also be a method of analysing current flow from a source to a destination.
It is connected in line with the main current carrying conductor and as the main flow of current passes through the shunt without restriction a tiny, but precise proportion passes along a parallel measuring path and this tiny current information goes to the monitor head.
The rating of the shunt is important as this defines the proportional size of current going to the monitor head. Use a shunt with the wrong rating and the monitor head will produce the wrong information (or may even be damaged). There are two rating aspects; total Amp capability and the millivolt rating. Total Amps is the limit that the metal block should be exposed to safely and the millivolts rating is that which the monitor head has been calibrated to for its calculations.
