DC Bias 6225

The DC bias of the 62X0 series is combined with the impedance analyzer 6632 (frequency up to 50MHz) and are controlled directly via the 6632 LCR or impedance meter. Up to 6 units of the DC current source series 6210 (10A) /6220 (20A) can be connected in parallel to provide a maximum current of 120A at 20Vdc. Up to 8 units of the 6240 (40A) can be connected in parallel at a maximum voltage of 12Vdc. The maximum current is then up to 320A. The 6632 offers a graphical current scan to check I sat and I rms. It offers analysis capabilities for temperature change and inductance saturation to see if a coil would burn out due to temperature.
