DC Ammeter Fl-2 50A 100A 200A 300A 75mv Rated Current 120%, 2 Hours. -40~+60℃, Relative Temperature ≤95% (35℃) Peacefair 0-300A

Product Name: FL-2 50A 100A 200A 300A 75mV DC Ammeter with Manganin Shunt Sampling Resistor

B-grade 75MV National Standard AC/DC Shunt

The shunt is primarily composed of a manganin strip and copper terminals welded together. There are two sets of terminal blocks on the connectors at both ends of the shunt: the outer set is the potential terminal for connecting to the power line, and the inner set is the potential terminal for connecting to the measuring instrument.

The FL-2 series shunt offers an accuracy of 0.5-grade, with a specification range of 50-300A and a secondary voltage of 75mV.

Note: This product is a national standard shunt, not a B-grade shunt. It complies with the standards of JB/T 9288-1999, GB/T 7676-1998, and IEC 61010-1:1999. Be wary of merchants selling B-grade shunts as national standard shunts.

Applications:
Fixed-value shunts are used to expand the current measurement range of instruments.

Main Technical Parameters:

1. Accuracy Class: 0.5-grade;

2. Environmental Conditions: -40~+60℃, Relative Humidity ≤95% (at 35℃);
