When you need to measure the current in a circuit, you can use a shunt resistor, also known as a current shunt resistor. Shunt resistors typically have a very low resistance value, much smaller than that of the circuit under test. This ensures that the power shunt resistor has very little effect on the overall circuit. Selecting the proper current shunt resistor resistance value can be determined based on the expected current range and required measurement accuracy.


Shunt resistors are widely used in various fields. Ammeter Shunt electronic can measure the current accurately and reliably, and realize the control and protection of the circuit.


Why choose DONGYA?

Wide Range of Options - Interchangeable shunts are available in a wide range of values, making it easy to find a shunt that suits the specific needs of a particular application.

What is a shunt?
A shunt is an instrument for measuring DC current, which is made according to the principle that a voltage is generated at both ends of a resistor when a DC current passes through it. Shunts are often used in power systems to measure the current flowing through high-current circuits, especially for systems where large currents exceed the capacity of normal current measuring devices or meters. Shunts consist of low resistance components, usually made of copper or other low resistance high thermal conductivity material. Resistors are usually placed inside metal enclosures to provide electrical isolation and heat dissipation. Then place the shunt in series with the circuit and measure the voltage drop across the shunt with an instrument such as a voltmeter.
How to choose a interchangeable shunt?

Dongya Interchangeable shunts are often used in electrical circuits to measure current. When selecting an interchangeable shunt, the following factors should be considered.

Shunt Accuracy: Make sure that the current reading taken from the shunt is as close as possible to the actual current in the circuit.

Shunt Resistor: The lower the resistance value, the better the sensitivity, but it also results in a larger voltage drop across the shunt.

Shunt Operating Current: Make sure the shunt is capable of measuring the maximum current of the circuit.

Temperature Coefficient: Consider any temperature changes in the application and select the shunt that best fits the expected temperature range.

Current Waveform: Consider the type of current waveform in your circuit, whether it is AC, DC, or pulsed.

Shunt Material: The shunt material must have a low temperature coefficient of resistance and low thermal resistance.
