Description

The SAC-150 is a flexible Rogowski current coil for accurate AC current measurement where split-core or solid-core CTs are difficult to install. Because the coil is a thin flexible loop without a magnetic core, it wraps around conductors of almost any shape and does not saturate. The S9.1 mini integrator converts the coil output into a linear voltage signal proportional to the measured current, making the SAC-150 suitable for power meters, power quality analysers, motor protection and industrial monitoring.

The coil is supplied with the S9.1 integrator: 2000A rated input (customizable), 333mV / 3V AC rms output over a 10Hz ~ 20kHz bandwidth, Class 0.5S accuracy, phase error ≤0.5° and a response time of ≤1ms. The integrator is powered by 5V DC and consumes only 70mW; zero drift is ≤1mV and temperature drift ≤100ppm/℃. The coil is rated IP54, the housing is flame-retardant UL94 V-0, and the RJ12 output connects directly to Sinava meters and power quality analysers. As a Rogowski coil it has no secondary open-circuit hazard.

Function

The SAC-150 measures AC current with a flexible Rogowski coil. The coil output is the derivative of the measured current and is converted by the S9.1 integrator into an AC voltage signal proportional to the current, allowing the primary current to be read directly by a meter or analyser.
