Our offered Product range includes Manganin DC Shunt, DC Shunts and shunts.
DC Shunts is used to measure DC current; it allows the measurement of current which cannot be directly measured by a particular ammeter. In this situation the shunt acts as a resistor of exactly calibrated resistance, it is placed in series with the loaded so that all of the current to be measured will flow over it, and it provides a proportional millivolt drop across its terminals in parallel which can be measured by ammeter. Direct current instrument shunts are used to extend the range of ammeters whenever the flow of current to be measured is too large to be passed through the instrument—it can be manufactured for 1A to 15000Amp. The shunt is a diverter which is used to shunt majority of the current around the indicating instrument. The principle of current capacity using a shunt device depends on computing the small voltage released across a accuracy resistor placed in series with the load. Yokins offers typical parts that provide 50 mV and 100 mV outputs, but can also offer custom output voltages. The very-low-resistance values required for shunt resistors, 10 mΩ at 5 A and just 0.05 mΩ at 1000 A.
The Yokins shunts are available from 1A up to 15000A with an accuracy of 0.5% & 1% as per ISI248. Standard voltage drop is 50mV, 60mV & 75mV. Intermediate current ratings, other voltage outputs, better accuracy and purpose built shunts can be supplied. Application Shunts provide an accurate DC milli volt signal to drive ammeter indicators, overload protection and control devices, especially for higher amperage. It supplies Voltage drop proportional to the DC current which is measured and indicated by a moving-coil milli voltmeter with the dial calibrated in Amps. Operating principle A current passing through the Shunt produces a proportional voltage drop. A moving coil instrument connected to shunt measures the voltage drop across the shunt terminals.Shunts are calibrated in such a way that they produce an accurately defined voltage drop (50mV, 60mV, 75mV and 150mV). Compact Low cost shunts We offer compact low cost shunts as well. These shunts are often requested for special applications for small size or low cost applications. We generally recommend continuous load of ½ or 2/3 times the rated current, in these shunts. These can also be provided from 1A upto 15000A with an accuracy of 0.5% & 1%. Standard voltage drop applicable is 50mV, 60mV & 75mV. Technical Specification for shunts as per IS 1248 :
