Danisense partners with National Instruments to provide current transducers for use in power analysis measurement signal conditioning

Stability, accuracy and ease-of-use highlighted

 

Key points:

  • Danisense products chosen for high accuracy, high bandwidth, low phase shift and quick connectivity
  • NI’s new RM-26999 integrates with the PXI platform and uses Danisense transducers to perform quality power analysis at a low price.
  • National Instruments offers 4 Danisense current transducers on the NI Shop

 

Taastrup, Denmark, May 2109…Danisense, the leader in high-accuracy current transducers for demanding applications, has revealed that National Instruments (NI) - a global leader in automated test and measurement systems – has selected Danisense products as its preferred current measurement sensor family for use with its RM-26999 4-channel power measurements conditioner. The Danisense DS50UB-10V, DS200UB-10V, DS600UB-10V and DS2000UB-10V current transducers features high accuracy, high bandwidth and low phase shift which are key requirements for accurate power measurement.

 

National Instruments’ RM-26999 is a rack-mounted, signal conditioning device that connects to simultaneous-sampling multifunction I/O devices for power measurements. It features four voltage input channels with peak voltages up to 2,000 V and four current transducer ports for current measurements. The current transducer ports are optimized for flux-gate transducers by providing all the power, communication, and signal lines required for accurate measurements. The RM-26999 can be used with the modular PXI platform, allowing test engineers to synchronize mixed measurements with their power analysis in one unified system. Engineers can use NI’s RM-26999 Getting Started Guide to select the correct components, safely connect hardware, install the necessary software, and acquire the first measurements in a power measurements system.

 “The RM-26999 was designed with Danisense sensors in mind,” according to Sam Burhans, the RM-26999’s Product Manager. “This device measures voltage up to +/-2,000 V directly, and measures indirect current up to +/-2000A thanks to the stable, isolated, and accurate Danisense current transducers. We designed the systems for quick connectivity - only a single cable is necessary to connect the RM-26999 to the Danisense transducer.” NI currently offers four models of Danisense’s isolated current transducers with voltage output. The models offered have measurement ranges of +/- 50A, +/- 200A, +/-600A, and +/-2000A and require a power supply, digital communication, and output signal lines.

Comments Loic Moreau, Sales & Marketing Director, Danisense A/S: “We are excited that National Instruments references and selects our current sense transducers for use with their signal conditioning equipment, and that the guide acknowledges that connection and installation is simple, and that the results are stable and accurate. It is a pleasure to be working with a respected industry-leading company.”

Danisense current transducers used at CERN in particle booster PSU

Extreme accuracy and immunity to magnetic fields required by renowned international physics institution

 

Key points:

  • Accuracy required to ensure quality of beam injected into the LHC
  • <1ppm resistance to magnetic fields of 1mT
  • Noise levels reduced to better than 30ppm pk-pk (1MHz bandwidth)
  • In-house manufacture enabled flexibility

 

Taastrup, Denmark, April 2109…Danisense, the leader in high-accuracy current transducers for demanding applications, has announced that its current transducers have been used by teams at CERN as part of a significant upgrade program. The Danisense zero-flux DC current transducers (DCCT) are used in the design of QTRIM power supplies for the PS booster accelerator which are part of a chain of accelerators that inject the beam into the LHC (Large Hadron Collider) at the European Laboratory for Particle Physics.

 

The upgrade, explains Miguel Cerqueira Bastos, team leader for the section at CERN which manages high precision current measurement for power supplies, will “increase the beam energy in the PS booster accelerator from 1.4GeV to 2GeV”. Stability and linearity in the order of 10ppm as well as noise performance of under 10ppm pk-pk for a 10kHz bandwidth were required for currents of 1000A - the quality of the beam is strongly dependent on the quality of the current measurement provided by Danisense. Other demanding specifications required by the CERN team included very high immunity to magnetic fields in the order of a few mT - which can be present in some locations - and tight noise controls on the outputs of better than 30ppm pk-pk with a 1MHz bandwidth.

 

Comments Loic Moreau, Sales & Marketing Director, Danisense A/S: “This is a significant win for Danisense, as it demonstrates the extreme accuracy of our Fluxgate technology and our ability to custom-build solutions for very demanding applications. In this instance we developed the CERN DCCT with a separate sensing head. We had to increase the magnetic shielding which is a complex process since it is built into the core windings. However, because we maintain all significant manufacturing processing in-house at our facility in Denmark, we were able to develop a solution and implement it quickly.

Concludes Bastos: “Danisense was very co-operative and willing to learn about our needs. In the end I believe that they have been able to improve the performance of some of their standard product range, so the experience has been beneficial for both sides.”

High-accuracy, large aperture current transducer from Danisense measures up to 1200Arms

Targets testing of high power converters for today’s electric and hybrid vehicles

 

Key points:

  • Measure signals up to 1200Arms/1500A DC
  • Excellent linearity (<1ppm) and very low offset (12ppm)
  • High bandwidth to 300kHz for SiC and GaN technology
  • Large 45mm diameter aperture facilitates ease of use
  • High EMC robustness provided by metal housing

 

Taastrup, Denmark, January 2109…Danisense, the leader in high-accuracy current transducers for demanding applications, today announced the DM1200, a high-accuracy current transducer capable of measuring signals up to 1200Arms and 1500A DC. Specifically targeting the eV and heV markets which requires higher power converters that can be rapidly-charged, the DM1200 also features a large, 45mm diameter aperture which makes testing easier and more cost-effectively as frequent installation and replacement of the system under test can be performed without the need to remove the primary cable connector.

Like all Danisense current sensors, the DM1200 is based on a closed loop system, powered by a flux gate as the magnetic field detector. This zero-flux technology enables the DM1200 to feature excellent linearity of <1ppm with a very low offset of 12ppm and very low amplitude and phase shifts. These parameters are critical for accurate measurement of the efficiency of the converter, as they cause measurement errors.

Comments Henrik Elbaek, CEO, Danisense A/S: “The E-mobility industry is a game-changer for power converter test and measurement tools. The increase in power combined with higher switching frequencies means that we must deliver higher performance, rugged and very accurate products, and the DM1200 is our first product to be specifically-designed to meet all these requirements.

The DM1200 also features a high bandwidth of up to 300kHz, to match increased switching speeds, especially of SiC and GaN devices. In order to shield against EMC disturbances caused by these high frequency signals, the DM1200 incorporates a metal body as a shield. Horizontal and vertical fixations are included to provide flexibility for the test bench mechanical design.

The DM1200 is part of a range of high-accuracy current sense transducers from Danisense that spans 50 to 10,000Arms
