Overview
The Micsig RCP series Rogowski current probe measures AC currents up to 12000 Apk, offers a maximum bandwidth of 30MHz. With nearly zero insertion impedance, the probes minimize interference to the circuit under test. The coil features extremely high voltage resistance (up to 10 kVpk). Customization is available for coil cross-sectional diameter, perimeter, wire length, voltage withstand capacity, and operating temperature, enabling adaptation to complex application scenarios. It features a standard BNC interface for use with any oscilloscope. Its compact, flexible design easily solves the hard-to- reach part issue, and the coil diameter supports customization to meet more test requirements.
