The OC7000 Series combines high-current measurement capability with wide bandwidth and accurate signal transfer for power electronics, electrical testing, maintenance, and troubleshooting applications. Three models are available: OC7015, OC7030, and OC7050, offering bandwidths of 12 MHz, 6 MHz, and 5 MHz respectively. Depending on the model, maximum measured current ranges from 150 Arms to 500 Arms, with peak current capability from 300 Apk to 750 Apk. Each probe provides two selectable measurement ranges and corresponding current transfer ratios, allowing accurate measurement across different current levels. The probe includes overcurrent protection as well as audible and visual alarms to help protect the instrument from excessive current and overheating.
