Benefits of CoolSiC MOSFETs in Bi-Directional Inverter Applications - July 2021
With the move to renewable energy, there is an increased focus not only on generation but also storage, to make the most of the intermittent supply from wind and solar. Batteries are the common...

Three transducers have Hall-Effect ASICs
The models, for 6, 10 or 25A nominal measurements of DC, AC, and pulsed signals benefit from the revised open-loop Hall-effect ASIC introduced with the HO 8, 15 and 25-NP and –NSM models. The HO 6, 10 and 25-P models’ offset and gain drift are twice as accurate (over the temperature range -25 to 85ºC) as the previous generation, says the company. They provide an aperture of 8 x 8mm to carry the primary conductor under measurement. There is a high level of insulation between primary and measurement circuits, due to the high clearance and creepage distances of more than 8mm and a CTI (comparative tracking index) of 600, allows a test isolation voltage of 4.3kV RMS/50Hz/1min. The transducers require an area of only 2.88cm² and weigh 10g. The transducers also provide fault reporting should the memory contents be corrupted. The transducers operate from a single supply voltage at 3.3 or 5V.
