Description
Manganin High Precision Current Shunt Resistor for Power Supply Applications
A current shunt—also known as a current sense resistor—is a low-resistance device used to measure current in a circuit. It is placed in series with the load, allowing current to pass through it.
These shunt resistors are widely used in power electronics, battery management systems (BMS), motor drives, and industrial automation. They offer a precise, stable, and cost-effective way to monitor and control current in both AC and DC systems.
Applications:
- Drive technology, Home Appliance.
- Current Sensing, Power Electronic, Automotive electronics, Communication System/Current Shunt Resistor /Current Sense Shunt / Current Sense Resistor/Battery Shunt/DC Shunt/Shunt Resistor for Power Supply
