DC Current Bias Supply
DC1000A
To guarantee the quality and performance of inductive components such as inductors, chokes and transformers they are tested at their real-life operating point. If the inductor is designed to carry a DC current, then its inductance must be measured with that DC current present. Until now, these measurements were made by an LCR meter connected via special interfacing to a DC bias supply available only from the manufacturer of the LCR meter. The unique NEW DC1000A can be used with any precision LCR meter and connects simply into existing test fixturing.
