Having manufactured wire wound resistors for well over 50 years there are very few applications that we have not come across. Current sensing resistors are often required in applications from motor speed control, electric motor overload sensing circuits and the likes. With the increased uptake of solar power in Australia in recent years, both off grid and grid connected there have been a number of local manufacturers (particularly in South Australia), involved in the manufacture of solar inverters ranging from 50 watts up to several kilowatts. One of the requirements of switch mode solar inverters is the need for a […]
