Chapter 1 General Information
1.1 Introduction
ST1778 DC Bias Current Source adopts high-performance MPU and can provide a constant current
ranging from 0A to 20A. The maximum current output can reach 0-120A by connecting up to five slaves.
ST1778 can be used with most of Sourcetronic
’s L meters and LCR meters. ST1778 provides a
convenient and practical DC Bias Current Source for AC+DC overlap inductor measurement and
magnetic material analysis.
