I. Product Overview
The S1 is a high-precision Rogowski coil integrator with a precision-shielded aluminum alloy housing. It features a built-in low-ripple DC power supply module and is compatible with any type and size of Y-FCT/FCT Rogowski coil. It is a replacement for traditional CTs and is suitable for high-power load analysis, pulsed current monitoring, DC ripple measurement, and other applications.
