200A Current Transformers for Sofar Smart DTSU666

The LCTA9CC 200A/100mA current transformer is designed to work with Chint Smart Meters (DTSU666) as a necessary measurement element when connecting CT. It provides conversion of the primary current of 200 A to a secondary signal of 100 mA, enabling accurate measurement and integration with the inverter's measurement system.

Manufacturer and Compatibility: The transformer described in the catalog sheet is listed as a required element for cooperation with Chint DTSU666 meters used in storage systems and SOFARSOLAR inverters (in the product sheets HYD 3PH and related accessories). The designation used in the documentation: LCTA9CC-200A/100mA.
