  • Specification

The Rogowski SS-280A Series is engineered for precise, non-intrusive current measurement in high-speed power electronic environments. With its 1.7mm ultra-slim sensor coil, it enables direct contact with TO-type package components such as MOSFETs and IGBTs, which are widely used in switching power supplies and energy conversion systems.

Thanks to its 30MHz frequency response, the SS-280A Series captures fast transient waveforms generated during power device switching, making it ideal for design validation and EMI diagnostics. It supports an extensive current range from 30A to 30,000A, accommodating both ripple current and surge testing.

The absence of a magnetic core eliminates the risk of saturation, ensuring stable performance even during high-current pulses. Its wide operating temperature range from -40ºC to +125ºC makes it suitable for use in harsh environments and thermal chambers.

Whether for lab, production line, or field deployment, the SS-280A Series provides engineers with the reliability, flexibility, and precision needed for modern power electronics testing.
