CP4070 AC DC Current Probe 150 kHz Bandwidth 70 ArMS Continuous 200 A Peak

The CP4070 current probe from Siglent is a reliable AC/DC clamp probe designed for general-purpose electronics and industrial applications. It features a DC to 150 kHz bandwidth and supports 70 ArMS continuous current and up to 200 A peak current. With dual-range attenuation ratios (50 mV/A and 5 mV/A), the probe offers flexibility across low- to high-current measurements. It achieves high DC accuracy—±3%±20 mA in low range and ±4%±200 mA up to 140 A peak (±15% beyond that), depending on the selected range. Powered by a standard 9 V battery, the CP4070 includes auto-zero calibration and an overload indicator for user convenience and safety. The device clamps cables up to 10.3 mm diameter and connects via a 1 m BNC output cable, making it suitable for both oscilloscopes and multimeters. Compact and lightweight, this probe is ideal for power electronics, industrial maintenance, and troubleshooting high-current circuits.
