IN Brief:
- Danisense will introduce the MBC4000I fluxgate AC/DC current transducer at PCIM Europe.
- The device provides measurement up to 4000A and beyond, with accuracy below 0.05%.
- High-current power systems are putting greater pressure on current measurement, isolation, and thermal design.
Danisense will launch the MBC4000I, a compact fluxgate AC/DC current transducer for high-current measurement up to 4000A and beyond, at PCIM Europe 2026 in Nuremberg.
The company will exhibit from 9 to 11 June in Hall 7, Stand 429, where it will also show the MK500ID DC and AC current clamp-on for galvanically isolated measurements up to 500Arms. Together, the devices extend Danisense’s current-measurement range across fixed high-current installations and clamp-on test applications.
Based on closed-loop fluxgate technology, the MBC4000I is designed for measurement environments where accuracy, offset drift, aperture size, and temperature behaviour influence both control and validation. The device provides accuracy below 0.05%, low sensitivity drift, current-output performance, a Ø121mm aperture for busbar applications, and a 1:5000 primary-to-secondary ratio.
The large aperture gives the device a role in busbar-based power systems, where high-current conductors often form part of the mechanical architecture of converters, cabinets, battery systems, and test benches. In those layouts, measurement hardware has to fit around the conductor without disturbing the current path or adding unnecessary installation complexity.
Danisense’s MK500ID current clamp-on adds a portable measurement route for AC and DC current up to 500Arms. It provides a phase shift of 0.05° at frequencies below 100Hz and high-frequency bandwidth up to 1MHz, supporting power analysis and dynamic measurements where phase error or bandwidth limits can distort efficiency results, switching behaviour, or control-loop assessment.
Current sensing is becoming more demanding as electrification, AI power infrastructure, and industrial conversion systems move toward higher current and higher power density. Silicon carbide and gallium nitride switching can reduce losses and enable faster conversion, while the surrounding sensing layer must preserve accuracy, isolation, and stability under greater electrical and thermal stress.
Gate-driver and sensing development is moving in the same direction. Allegro’s PCIM focus on current sensing and isolated gate drivers reflects the need to coordinate measurement, drive, and protection functions around faster SiC and GaN power stages.
Busbar power distribution is also gaining ground as systems move away from cable-heavy layouts. Busbars can reduce parasitic inductance, simplify packaging, and improve current handling, although they create their own sensing and serviceability requirements. A transducer designed around a large aperture and stable low-drift behaviour fits that shift, particularly where system currents are moving into the kiloamp range.
PCIM Europe will again bring together many of the power-density pressures now shaping data-centre power, renewable conversion, industrial drives, EV infrastructure, and battery systems. TDK’s PCIM programme for AI data-centre power spans passives, sensors, contactors, DC/DC conversion, capacitors, and thermal behaviour, showing how closely measurement and power conversion are now linked.
The MBC4000I sits in the measurement layer that allows high-current systems to be controlled and verified. As power architectures scale, current measurement becomes part of the system’s performance rather than a secondary test function.
