PEM Rogowski coil 1.2 mm ultra-fine ultra-mini CWTUM-S/06 high-frequency current probe 120 A/30M

CWTUM-S is a thinner version of PEM's original CWT UltraMini probe. The Rogowski coil has a cross-sectional diameter of only 1.2mm, without compromising operating temperature, high-frequency performance, or insulation voltage. This thin coil offers another solution for measuring current in tight spaces without disturbing the tested circuit.

The wideband AC current probe with BNC output can connect to most types of oscilloscopes or data acquisition devices.

Main Features

• Wide operating temperature range: -40°C to 125°C.

• High frequency (-3dB): 30MHz.

• Loads the tested circuit by only a few pH.

• Standard coil length (circumference) of 80mm.

• Coil insulation 1.2KV PK, 1.2mm cross-sectional diameter.

• Peak DI/DT capability up to 100KA/μs.

• Current rating from 30A PK to 30KA PK.

Applications

• Switching current waveforms in circuits: small MOSFET or IGBT devices in TO-220, D2PAK, and other SMT power devices.

• Measuring power loss in semiconductor switching lines of power devices.

• Monitoring currents in small inductors, capacitors, snubber circuits, etc.

• Measuring small AC currents in the presence of large DC currents (such as monitoring capacitor ripple).

• Development and diagnostics of power converters.

• Measuring high-frequency sine, pulse, or transient currents at power frequencies up to RF applications.
