CR Magnetics Current Indicators are the recognized industry standard in simple but effective electrical circuit
monitoring. These indicators can be used to check the status of AC current carrying conductors, and can provide an easy
method to tell the operation of heaters, motors, fans, and other AC electrical equipment without disconnecting power and
physically measuring connections and equipment. AC current in a conductor induces the LED to light, indicating the pres-
ence of AC current in the conductor. Failure of the LED to indicate suggests open heater elements, broken motor leads,
and failed fuses without physically measuring the circuits. Value priced and available in all-in-one and remote indicating
packages, these products provide payback by saving downtime and maintenance costs.
CR Magnetics supplies a variety of standard Solid Core and Split Core Current Transformers
designed for measuring electrical systems. These components provide the building blocks to interface most industry
standard and customer designed electrical power monitoring systems and equipment. Our transformer line includes
ANSI and Commercial grade industry standard parts, as well as PC Board mounted designs for cus-
tom and OEM controls. We carry an extensive line of Medium Voltage (above 1KV) products for the utility and
industrial markets. Also unique to CR Magnetics are our Power Meter class of transformers with better than
0.2% accuracy. Finally, a line of Ground Fault transformers are available as well that provide
accurate measurement of extremely small ground fault currents. Whatever the application, CR
Magnetics can provide the exact product to meet industry’s continually changing
needs. Most products can be used as interfaces with other CR Magnetics products,
and are UL and CSA approved.

CR Magnetics carries an extensive line of Potential Transformers that are used to monitor and measure
various levels of AC Voltages. Typically modeled similarly to common power transformers, potential
transformers are specially designed to provide accurate input versus output curves over a wide range
of loading. Whereas power transformers are typically designed for 70 to 80 percent regulation, potential
transformers are desinged for 99% or better regulation.
