Transistor Generator/PTG type

Highly regarded for its ability to conserve both space and energy, the cutting-edge high frequency generator PTG Type finds wide use in high-frequency applications.

  • 1.More compact than conventional oscillators (compared to DKK products).
  • 2.There is no need for water purification equipment.
  • 3.There are no high-voltage parts since the matching network is a parallel, resonance type which simplifies maintenance and allows more freedom in installing the unit.
  • 4.Circuit design is simple, without the need for the commutator or starter circuits of thyristor inverters.
  • 5.Superior compatibility and reliability in the face of varying load conditions.
  • 6.Maintenance is easy with modular packaging of transistor elements.
  • 7.Economical: Saves energy and water. Output adjustment is selectable from constant power, constant voltage, and constant current.
