Dual-frequency generators

Dual frequency generators from eldec: an energy source designed in Germany

eldec is well-known for its SDF® technology – patented dual-frequency generators which can be operated simultaneously or separately with medium and high frequency. Although SDF® generators are suitable for users looking for a generator with a switchable frequency, but do not want simultaneous frequency, they are often too expensive.

We can now supply DF generators (dual-frequency generators) for these applications: switchable dual-frequency generators with the product and service quality you expect from eldec.

Dual-frequency generators

Dual frequency generators from eldec: medium and high frequency from the same generator

Operating modes:

  • permanent, jog, timer
  • Control types: output, electricity, temperature
  • Profibus
  • Optional heating with medium and high frequency
  • Medium frequency – higher case depth;
    High frequency- shallower case depth
  • Robust IGBT transistor technology => short-circuit and open-circuit proof
  • Efficiency > 90%
  • Automatic adjustment to resonance frequency and thus inductor impedanc
  • Precise energy dosing (+/- 2%) => high process capability (reproducibility)
  • Largest frequency and power range and largest adjustment range on the market

Technical Dates

MF frequency ranges:

  • 8-20 kHz, 10-25 kHz or 16-40 kHz

HF frequency ranges:

  • 140-350 kHz or 160-400 kHz
  • DF generators are available in various output rating combinations of the medium frequency range with the high frequency range.

The following output rating combinations can be selected as required
