DC Bias Current Source/System

MICROTEST DC Bias Source Test System provides precise verification of magnetic components' magnetic saturation current (Isat) and temperature rise current (Irms). It is equipped with a DC bias current source integrated with an LCR meter/Impedance Analyzer and can be configured as a desktop unit or integrated into a testing cabinet. Operation settings and test results are displayed on the LCR meter/Impedance Analyzer and can also be accessed through PC connection software.

The DC bias current output ranges up to a maximum of 640A/120A/60A/20A, with frequency responses of 100Hz-30MHz/10MHz/3MHz.

For research and development (R&D) or scientific research institutions, there is the option of the 6632+ / 6632S+ series, which includes a current curve sweep analysis feature.

For production lines, the 6350+ series is available as an option.
