CURRENT SENSE INDUCTORS

APPLICATIONS

AF3259

Vitec Electronics' Current Sense Inductors shown on this data sheet are the secondary portion of a currenttransformer created by the user placing a turn or more through the center hole of the package. The currentflow through the turn or turns installed by the user are detected by Vitec's inductor and is converted toproportional but smaller current that is then used in the following applications:

Overload Sensing

Ground Fault Detection

Metering

Analog to Digital Circuitry

Power Limiting Controllers in Industrial Applications
