The FRS 3000-SUI is an open-loop coreless integral (OLCI) current transducer designed for electronic measurement of DC, AC, and pulsed currents with galvanic separation. It features a fast Rogowski-based small design with a 104 mm aperture and provides an instantaneous unipolar 4-20mA output signal. It is factory calibrated and specifically engineered for high-power industrial and traction applications.
