Selection Guide

How to choose the right DC Shunt for your application

Step 1: Determine Current Requirements

Identify the maximum current that will flow through the shunt in your application. Select a shunt with a current rating that exceeds this value by at least 20% for safety margin.

Step 2: Consider Accuracy Needs

Determine the required measurement accuracy for your application. Higher precision applications may require shunts with accuracy classes of 0.05% or better.

Step 3: Evaluate Environmental Conditions

Consider the operating temperature range and environmental conditions. Applications with significant temperature variations may require shunts with lower temperature coefficients.

Step 4: Check Voltage Drop Requirements

Verify the voltage drop requirements of your measurement system. Standard options include 50mV, 75mV, 100mV, and 150mV.

Step 5: Consider Mounting and Space Constraints

Evaluate the available space and mounting options in your application. Different series offer various mounting configurations and sizes.
