FAQs
What is a 300A 75mV DC Manganin shunt resistor used for?
It’s used to measure current by creating a small, known voltage drop (75mV) across a resistor rated for 300A. It allows accurate current sensing in DC systems like EVs, solar, and UPS.
Can this shunt resistor be used for battery monitoring?
Yes. It is ideal for Battery Management Systems (BMS) in electric vehicles and stationary energy storage.
Is the FL-2P shunt resistor customizable?
Yes, current ratings (100A–600A) and voltage drop values (50mV or 75mV) can be selected to meet your project’s needs.
What is the standard operating environment?
It performs well in most industrial and outdoor environments, but exact ratings depend on your system’s thermal management and enclosure.
What materials are used in the FL-2P model?
The main components are brass ensuring low thermal EMF and high stability.
What accuracy class is available?
FL-2P offers Class 0.2% and 0.5%, making it suitable for both standard and high-precision applications.
