VOLTCRAFT VC-15D Flexible Rogowski Coil AC Current Clamp Adapter, 10000 A, CAT IV 600 V, 4 mm Banana Output VC-17500290

The VC-15D from VOLTCRAFT redefines high-current measurement by replacing rigid clamp jaws with a flexible Rogowski coil, allowing you to wrap around conductors up to 140 mm in diameter and measure AC currents up to 10000 A without interrupting the circuit. Unlike traditional clamp meters, this adapter connects to any multimeter with 4 mm banana inputs, turning your existing meter into a high-range current logger or monitor. Its dual-range output (1 mV/A on the 1000 A range, 0.1 mV/A on the 10000 A range) ensures compatibility with a wide range of instruments, while the CAT IV 600 V safety rating provides confidence even in industrial power distribution environments.

Highlights

• Flexible Rogowski coil with 450 mm loop length and 140 mm max conductor diameter for easy access to large or awkward conductors
• Wide measurement range from 0.1 A to 10000 A AC, covering everything from leakage currents to heavy industrial loads
• Dual output ratios: 1 mV/A (1000 A range) and 0.1 mV/A (10000 A range) for optimal resolution on different multimeters
• Safety rated CAT IV 600 V and CAT III 1000 V for use in power distribution and fixed installations
• Frequency response 40 Hz to 500 Hz, suitable for mains and variable frequency drives
• Powered by 2 AAA batteries (included) with auto power-off to preserve battery life
• 1.5 m output cable with 4 mm safety banana plugs for universal multimeter connection

In daily use

Electricians and maintenance technicians will appreciate how quickly the VC-15D can be deployed. Simply loop the flexible coil around the conductor, select the appropriate range on your multimeter, and read the current directly. The coil's flexibility allows measurement in tight panels, around busbars, or on multiple parallel conductors. With an accuracy of ±1% of reading at 50-60 Hz, you can trust the readings for energy audits, load balancing, and troubleshooting. The adapter's low output voltage (max 3 V) and safety banana plugs ensure safe connection to your meter. When not in use, the coil can be coiled for storage, and the auto power-off function prevents battery drain.
