Programmable three-phase source of current and voltage (phantom power)
The source was modernized to provide single / three-phase current and voltage test signals suitable for testing power quality according to IEC 61000-4-30 (including generation of harmonics up to 50th and interharmonics).
Energoforma 3.3 current and voltage (phantom power) source is designed to create a three-phase or single-phase system of currents and voltages, as specified by the programmable digital model of the signal.
