The Teledyne LeCroy T3RC3000-LF is a flexible Rogowski AC current probe engineered for non-intrusive measurement of AC currents up to 3,000 A across a bandwidth of 0.11 Hz to 6.5 MHz. Its open coil design eliminates the need to break circuit connections, making it ideal for power electronics, motor drive, and inverter characterization in both laboratory and field environments.
