The purest source current up to 200 A

Power Series

The purest source current up to 200 A

The water chilled unipolar (UCS) and bipolar (BCS) current sources deliver up to hundreds of Amps with so far unprecedented precision and fast response. The constant low temperature of the water chilled power electronics results in extremely high stability and low noise figures. The Power-Series feature all comfortable control units. The operation of the Power-Series is just as easy as of any other of HighFinesse’s current source.
