Small Current Transducer Sports 10-ppm Maximum Linearity Error
Designers of PCB-mounted power electronics will see the need for a small current transducer that handles up to 18 A. That’s what you get in Danisense’s DP12IP, which is designed for isolated DC and AC current measurements.
Based on the company’s closed-loop compensated fluxgate technology, the DP12IP series combines a maximum linearity error of just 10 ppm and high long-term stability. The device comes in a compact PCB-mount package featuring a form factor of only 32 mm in height and weighing only 250 g. Thus, it can be integrated into 1U power supplies and other space-constrained equipment.
The transducer supports current measurements up to 18 A and accommodates measurement resistors up to 100 Ω at full scale. It uses fixed excitation frequency and second-harmonic, zero-flux detection to deliver highly stable and precise current measurement performance.
Typical applications include magnet power supplies for particle accelerators, stable precision power supplies, precision servo drives for motion control, battery test benches, battery emulators, and power-measurement and power-analysis systems.
