As power systems handle larger loads, a new current measurement approach aims to support testing, monitoring, and performance analysis.
Danisense has introduced the MBC4000I fluxgate AC/DC current transducer for high-current measurement applications, supporting AC and DC current measurements of up to 4000A and beyond. The device is designed to provide measurement performance significantly higher than conventional Hall-effect current transducers.
The transducer can be used by engineers and system designers working in power electronics, renewable energy systems, battery testing, industrial equipment, grid infrastructure, and other high-current applications. It enables users to monitor, measure, and analyze large currents with high accuracy, helping improve system testing, performance evaluation, efficiency monitoring, and fault detection.
Built on Danisense’s closed-loop fluxgate technology, the MBC4000I delivers accuracy better than 0.05% across a temperature range of -20°C to +85°C. It also offers low sensitivity drift and stable current output, helping maintain reliable measurements under varying operating conditions.
Designed for busbar applications, the transducer features a large 121 mm aperture and a primary-to-secondary ratio of 1:5000. It also maintains low offset drift across temperature changes, making it suitable for environments where precise measurement of high currents is required.
“As electrification expands across industries as part of the global energy transition, power generation and consumption levels continue to rise. This is creating a growing demand for current measurement solutions that can accurately monitor currents of 4,000A and above,” said Loic Moreau, Sales and Marketing Director at Danisense. “Improving power converter performance in areas such as power quality, efficiency, and system stability also requires current measurement technologies with higher accuracy, long-term stability, and low temperature dependence. In many high-performance applications, conventional closed-loop Hall-effect current transducers are reaching their limits in terms of linearity, offset drift, and measurement precision,” he added.
“These challenges led our engineering team to revisit and redesign Danisense’s fluxgate measurement principle. The result is a new generation of current transducers that delivers measurement performance up to ten times higher than traditional Hall-effect sensors,” Moreau said.
