Compact PCB-Mounted Current Transducer Delivers High Precision

Danisense’s high-precision current transducer is designed for isolated DC and AC current measurement in PCB-mounted power electronics.

Danisense’s latest high-precision DP12IP current transducer is designed for isolated DC and AC current measurement in demanding PCB-mounted power electronics applications.

Based on Danisense’s closed-loop compensated fluxgate technology, the DP12IP series combines ppm-class accuracy with a maximum linearity error of 10 ppm and long-term stability in a compact PCB-mount package featuring a form factor of only 32 mm. This allows for integration into 1U power supplies and other space-constrained equipment, Danisense said.

The transducer handles current measurements of up to 18A 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 measurements. Typical applications include precision power supplies and servo drives for motion control as well as battery test benches, battery emulators, and power measurement and power analysis systems.

Lee Goldberg is a self-identified “Recovering Engineer,” Maker/Hacker, Green-Tech Maven, Aviator, Gadfly, and Geek Dad. He spent the first 18 years of his career helping design microprocessors, embedded systems, renewable energy applications, and the occasional interplanetary spacecraft. After trading his ‘scope and soldering iron for a keyboard and a second career as a tech journalist, he’s spent the next two decades at several print and online engineering publications.

Lee’s current focus is power electronics, especially the technologies involved with energy efficiency, energy management, and renewable energy. This dovetails with his coverage of sustainable technologies and various environmental and social issues within the engineering community that he began in 1996. Lee also covers 3D printers, open-source hardware, and other Maker/Hacker technologies.

Lee holds a BSEE in Electrical Engineering from Thomas Edison College, and participated in a colloquium on technology, society, and the environment at Goddard College’s Institute for Social Ecology. His book, “Green Electronics/Green Bottom Line - A Commonsense Guide To Environmentally Responsible Engineering and Management,” was published by Newnes Press.

Lee, his wife Catherine, and his daughter Anwyn currently reside in the outskirts of Princeton N.J., where they masquerade as a typical suburban family.
