Technical Setup

97% Efficiency

Besides the high efficency of the bi-directional test system it provides extensive setting options which can be accessed via the touch display or an optional PC as control unit running a remote control terminal or Solfas Test Suite 2 for complex test sequences. The complete remote control allows safe testing from the control desk and increases productivity and safety.

It allows a wide variety of loads with capacitive, ohmic or inductive characteristics to be operated.

Regenerative DC Power Supply

The PSD100 series power supplies are able to source or sink current, the energy flow can be in both directions.
By the high efficient power electronics an output voltage with low ripple is generated.
Output voltage and current are measured and controlled with high accuracy.
