FAQs
What does a 50A 75mV DC current shunt resistor do?
It converts a 50-amp current into a measurable 75mV voltage signal, allowing meters or controllers to accurately calculate current flow.
Can this shunt be used with digital panel meters?
Yes. The 75mV output is compatible with most digital and analog ammeters calibrated for external shunts.
What is the accuracy level of this current shunt?
Standard models are available in 0.5% and 0.2% accuracy classes, suitable for most non-critical and industrial monitoring needs.
How should I install the shunt?
Install the shunt in series with the load. Voltage drop terminals should be connected to your measuring device. Mount on a non-conductive or insulated base for safety.
Why is it called a “Russia-type” current shunt?
“Russia-type” refers to a traditional mechanical design common in Eastern European electrical standards, with a robust and open-terminal layout.
What are the materials used in the FL-13 model?
The shunt features brass terminals for excellent conductivity and a manganin resistive strip, known for its low-temperature coefficient.
Is the FL-13 suitable for solar DC systems?
Yes, it performs well in solar charge controllers, inverter input circuits, and DC combiner boxes.
How do I know if this shunt is the right fit?
Match your system’s full-scale current (50A in this case) and required voltage drop (75mV). Compatibility with your meter is key.
