INDUCTION GENERATOR PFG60K25S2


Compact Induction generator PFG60K25S2 is purposed for wide need in metal industry, for induction hardening, forging, melting welding or optical fiber industry.

 

Characteristics and advantages

  • Compact design and small dimensions of the generators with separate output LC unit with transformer and capacitor battery with connection for a quick change off inductor coils.
  • Separate LC-heating unit, connected to Generator due flexible leads lengthup to 7m with power connectors, for easier access to appliance or automatically serving plant.
  • Aluminum casing of generator and the output part
  • Small weight of the whole unit
  • Output Power regulation from 6 to 100% with step per 1% (Control unit)
  • Over voltage and overload protection on output
  • Dynamic short-circuit protection of the IGBT transistors
  • Thermal protection of the power semiconductors
  • Adjustment possibility of two-time intervals -timers (T1+T2 -240s, P-from 6 to 100%) with adjustment of two output power levels in sequence
  • On O-LED 4x20, display countdown- time- warming intervals with simultaneous display of output voltage, power and output frequency with fault diagnostics
  • The most modern Power IGBT technology in combination with insensitive analog +/- 15V CMOS circuit regulation, controlled with processor unit
  • Pure parallel final resonant circuit, thereby high efficiency of the circuit and the static frequency inverter >90%
  • High reliability, simple handling and operation, Soft-Start
  • Connection on three-phase voltage, without neutral conductor
