DC Bias Current Source

The Sourcetronic DC bias current sources can be used for inductance measurement of inductors and transformer windings. ST DC bias current sources have a precise and constant current output up to 20A, a wide spectrum of responding frequencies and very low additional error. They can be controlled and operated with high frequency LCR meters like the Sourcetronic ST2816A, ST2817A, ST2818, ST2819, ST2828 and therefore are a perfect solution for testing the magnetic characteristics. With MPU controlled auto current balance technology the DC bias current sources from ST are adopted to realize AC+DC current overlap and constant current output.
