DF-C Series AC Industrial Power Supplies

High-performance AC power supplies of the DF-C series are designed for continuous industrial use and can operate completely maintenance-free and autonomously. These power supplies have optional digital or analogue connections and can be configured with a wide range of options.

 

Maximum values of the series:
2kVrms L-N / 15kA per phase / 1MVA / ØPL = 0.32€/W

 

DF-CM Series High Frequency AC Power Supplies

Developed for particularly power-intensive applications in laboratories and industry, the alternating current-laboratory power supplies of the DF-CM series are a high-frequency version of the proven DF-C series and are completely maintenance-free at power levels up to the megawatt range, even with continuous use. These power supplies have optional digital or analogue connections and can be configured with a wide range of options.

 

Maximum values of the series:
2kVrms L-N / 15kA per phase / 1MVA / ØPL = 0.32€/W

 

DF-S Series AC Laboratory Power Supplies

The DF-S series has the advantages of the more powerful DF-C series with lower power. Developed for laboratory use, these AC laboratory power supplies are very user-friendly and compact.

 

Maximum values of the series:
300Vrms L-N / 42A / 3KVA / ØPL = 1.20€/W
