CR Magnetics offers a versatile line of rugged wire
lead current transformers. Installed around a
current-carrying wire, the sensor provides a current
output relative to the AC input current (within
specification limits). With the output connected across
a resistive load (burden), the voltage
developed is proportional to the input current.
