CP4070A AC DC Current Probe 300 kHz Bandwidth 70 ArMS Continuous 200 A Peak

The CP4070A current clamp probe from Siglent delivers dual‑range AC/DC current measurement functionality up to 200 A peak and 70 ArMS continuous, featuring a DC–300 kHz bandwidth (–3 dB) and fast rise time ≤ 1.2 µs. It supports two output sensitivities—100 mV/A and 10 mV/A—with high DC accuracy: ±3%±50 mA for currents between 50 mA–10 A peak at 100 mV/A, ±4%±50 mA for 500 mA–40 A peak at 10 mV/A, and ±15% up to 200 A peak. Powered via a 9 V battery, it includes auto-zero calibration and an overload indicator. Ideal for industrial, power electronics, and general-purpose test applications, it clamps cables up to ~11 mm, with safety ratings of CAT III 300 V / CAT II 600 V. Weighing only 260 g, and with compact dimensions (~280 × 70 × 32 mm; packaged 32 × 26 × 9 cm), it's lightweight and portable for field or bench use.
