The Teledyne LeCroy T3CP150-12 is an AC/DC current probe delivering precise, non-invasive current measurements up to 150 A RMS with 12 MHz bandwidth. Engineered for power electronics, motor drives, and electric vehicle testing, this dual-range probe combines DC and AC measurement capability with selectable sensitivity (30 A and 150 A ranges) to capture both transient detail and steady-state behavior. The probe integrates dual-indicator over-current protection (audible buzzer and LED alert), automatic zero setting, and degaussing functions to maintain measurement integrity across extended test sessions. A compact probe head (176 × 39.5 × 18 mm) accommodates conductors up to 5 mm diameter, while the control box supplies range selection and user-initiated calibration controls. Connected via 1 m cable to the control unit, the T3CP150-12 interfaces with oscilloscopes through standard BNC high-impedance input.
