Product Description
The ULNRC-600 is a flexible, air-core current sensor which operates on the Rogowski Coil principle. The ULNRC-600 is designed and approved to be installed on insulated and/or bare conductors (bus bars).
The unique shielding system and precision windings minimize the positioning error and practically eliminate the influence of external magnetic fields.
The ULNRC-600 can be used directly with the WattsOn-Mark II Precision Energy Meters without an integrator or additional power supply. This offers accurate measurements in large power systems where conventional iron-core CTs may be hard to install.
Each ULNRC-600 coil has a unique serial number and is factory calibrated. Three identical coils are shipped with one meter for best accuracy.
The ULNRC-600 features UL Listing for easy retrofit in field applications.
