The PPS 400.3 is a powerful and portable three-phase current and voltage source. All test values are generated absolutely synthetically with a high degree of accuracy and stability.

The PPS 400.3 is available in two versions: — PPS 400.3-12 A (maximum current up to 12 A) — PPS 400.3-120 A (maximum current up to 120 A) The PPS 400.3, portable power source may be used as enhancement of the reference standard PRS 400.3 as well as independently. The control software automatically recognises the model. It may therefore immediately be taken into operation, and automatic measurement of a load curve of the meter may begin.
