PCB-mount current transducer features high stability and accuracy

Danisense has launched an ultra-stable, high-precision DP series of PCB-mount current transducers for isolated DC and AC current measurement up to 72A. With a footprint of 64.9mm x 60mm, a height of 32mm and light weight of 250g, this compact device is ideal for 1U power supplies and other space-constrained applications.

Benefitting from the company’s closed-loop, compensated Fluxgate technology which gives a fixed excitation frequency and second harmonic zero flux detection for excellent accuracy and stability, the series PCB-mount current transducers provide a maximum linearity error of 10ppm and a measurement resistance of up to 100Ohm at full scale. Devices are programmable for 12.5A, 25A, or 50A use via the PCB layout.

Applications incorporate MPS for particle accelerators, stable power supplies, precision drives, battery-testing and evaluation systems, power measurement and power analysis. Comments Loic Moreau, sales and marketing director, Danisense A/S: “Our technology has enabled us to deliver a PCB-mount current transducer with class-leading stability and accuracy. Its small size and low weight make it possible to include such high-performance measurement functionality on the PCB for the first time.”
