Product number: RCP500
Manufacturer: Micsig


The Micsig RCP500 current probe offers a measurable range in AC current from 200mA to 500A and a bandwidth from 15 Hz to 300 KHz. Thanks to the Rogowski coil design, the flexible loop can be easily wrapped around a cable, allowing measurements in hard-to-reach places. The RCP500 has an accuracy of 1% and noise of less than 2mV.  The compact design makes the RCP500 current probe ideal for mobile use and can be used on Micsig oscilloscopes without an external power supply via the UPI multifunction interface.

When used with any other manufacturer's oscilloscope, a universal adapter (PA05) is included to provide power to the probe via an ordinary 5V USB output. The AC current clamps can measure current signals with complex waveforms, such as transient inrush currents of power devices, sinusoidal currents of three-phase power systems, harmonic components of measured currents, current measurement of IGBTs and MOSFETs, etc.
