The CR8750 series Current Transformer provides a low cost method for monitoring electrical current. The transformer is intended to be mounted on a Printed Circuit Board with the current-carrying wire routed through the center window opening. A five-pin, non-symetrical mounting pattern ensures correct orientation on the PCB. Two different winding ratios are available to accommodate various applications. The graph below illustrates how different values of burden resistors attached to the output terminal will provide a number of different output voltage ranges.
