The Teledyne LeCroy T3RC3000-HF is a Rogowski AC current probe engineered for non-invasive, high-accuracy current measurement up to 3,000 A across an extended frequency range of 3 Hz to 23 MHz. The flexible coil design wraps around conductors without circuit modification, ensuring minimal loading on the device under test while capturing both low-frequency and transient phenomena. With a sensitivity of 2 mV/A, maximum noise of 1.4 mV rms, and peak di/dt capability of 80 kA/µs, the probe delivers precise waveform acquisition in power electronics, renewable energy, and component-level R&D environments. The 200 mm coil and 4 m cable support field deployment and benchtop integration. Rated for 5 kV peak insulation with operating temperature range of -40 °C to +125 °C, the T3RC3000-HF powers via battery or AC adapter for flexibility across lab and field conditions.
