In my previous article I wrote about current shunt resistor company and how they can be used to measure current. Today I would like to tell you about some other interesting things that current shunt resistors can do. They are also called current shunt regulators, current limit resistors, current swing resistors or simply current shunt taps. The way that they work is that they are used in conjunction with a current shunt that works by measuring the resistance to the flow of current.
The resistance across the current shunt regulator will then determine the output voltage that is provided to the device in question. For instance. a current shunt that has a resistance of say 0.1 Ohms and a current shunt that have a resistance of say 0.5 Ohms will create a voltage drop of about 0.5 volts or about 50mV.
As you can see from the example, the current shunt resistance has little effect on the voltage drop as the current shunt is not doing any kind of work. The current shunts then do all the work and they regulate the output voltage to a standard level. They help to ensure that there are no spikes in the output current and also help to prevent short-circuits.
There are a number of different current shunts that can be found on the market. However they are all designed to do the same job which is to regulate the output current for household electrical devices. They all have different advantages, although they must be matched to the different types of household electrical devices. As there are so many different types of household electronic devices one might assume that there would be more varieties available but this simply isn't the case.For more details about power resistors, View here.
In fact there are only a handful of different current shunts that are typically used for all of the different types of electronic devices. So, if you were to search around on the internet you would probably come across a few suppliers offering the shuns and also some information relating to the various different types of shunts that they offer. But even still you would probably find that the selection is rather limited.
So what then is the solution? Well there is actually an answer.
By taking the different current shunts and comparing them with the different types of household electronic devices we can then work out a way in which the shunts would be able to match up with each other. As there are only a handful of different types of shunts it means that they must have the correct compatibility between them. And by checking this out we then get a better chance of buying the right current shunt for our needs. This isn't something that most people think too much about but it's something that is very important and something that needs to be looked into when shopping around for shunts.
