Dual-Frequency Generators

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
