DC Current Shunts, Russian Type, 5A-3000A, 50mV, 60mV, 75mV, 100mV

DC Current Shunts are low resistance precision resistors used to measure AC or DC electrical currents by the voltage drop those currents create across the resistance.
Power Rating : Watts (W) = Current (I2) x Resistance Value (R)
The heat produced is power measured in Watts (W).
Current shunts dissipate heat from the current flowing through them, when they get hot.
In practice current shunt is often rated to be used continuously at only 2/3 of their "rated current".
Since that heat can change their resistance and even permanently damage the shunt, so it is often given a power rating or a derating factor.
Calculate Current : Current (I) = Voltage (V) / Resistance Value (R)
By inserting a current shunt into a circuit to get the current you want to measure while the voltage dropped across the shunt.
Then knowing the resistance of the current shunt you can calculate the current by using Ohm's law.

Jingdacheng Electronics(JDC) is a leading power resistors manufacturer in China, and we are always focusing on providing various resistors and loading solutions since it was established in 1997. With 24 years industry experiences, JDC has a professional team for resistor designing, manufacturing and quality control, and most of our managements have been working for JDC at least 10 years. Even approved by ISO9001:2014, JDC started proceeding a very high standard (Japan JIS) of manufacturing and quality inspection since we built a long partner cooperation with Japan IWAKI MUSEN in 2013. Now, JDC is providing many resistors and solutions for some top500 companies, Such as: Huawei, Yaskawa, Panasonic, Midea, etc.
