The Solid-Core S77 High Accuracy Current Transformers are designed to convert an AC operating current into a low voltage AC millivolt signal for use with microprocessor-based circuits.  These compact and light-weight solid-core current transformers are designed for installation on branch circuits for meter installations that require exceptionally accurate signal transformation. The S77 current transformer has been approved by Measurement Canada to be used in metering applications for installations used for billing purposes.  CTs come standard unterminated stripped and tinned lead wires for easy connection to any of the Single or 3 Phase ACI power meter.  CT models listed here are compatible with the ACI KW350-P1-D-S-SC, KW320-P1-D-W-SC-XX, KW320-P1-D-W-SC-PC, KW1850-P1-D-W, and KW1850-P1-D-S Power Meters where typical power measurements are required.  For best accuracy, CTs should be selected based upon the expected maximum and minimum currents for the targeted application.  The acceptable Measurement Current Range is referenced in the ordering grid table.
