eldec is well-known for its SDF® technology - patented dual-frequency generators capable of being operated separately or simultaneously with high or medium frequency. SDF® generators are often too expensive, despite being ideal for users seeking a generator with a switchable frequency, but do not want a simultaneous frequency.
Eldec supplies dual-frequency (DF) generators for these applications: switchable dual-frequency generators with the product and service quality customers expect from eldec.
Operating Modes:
- Largest frequency and power range and largest adjustment range on the market
- Precise energy dosing (+/- 2%) => high process capability (reproducibility)
- Control types: temperature, electricity, output
- Optional heating with high and medium frequency
- Automatic adjustment to resonance frequency and thus inductor impedance
- Robust IGBT transistor technology => short-circuit and open-circuit proof
- permanent, jog, timer
- Efficiency > 90%
- Profibus
- High frequency-shallower case depth; medium frequency-higher case depth
