PFG25K20R1

Transistor MF static frequency changer PFG25K20R1 with induction heating plant manufactured for the inductive heating up of steel tubes for example, preheat from uncoated tube ends on the temperature approx.. 180º - 200º C in oil and gas distribution industry.

Characteristics and advantages

• Compact design and small dimensions of the generators with separate output transformer with capacitor battery and Flexinduktor
• Compact building method and dimensions
• Output Power regulation from 10 to 100%
• Regulation and stabilization of MF –Output voltage, current and/or power
• Over voltage and overload protection on exit
• Dynamic short-circuit protection of the transistors
• Thermal monitoring of the power semiconductor large load adjustment by resonance alignment of the resonant circuit within range 75% to 125% of the nominal frequency
• The most modern achievement IGBT technology in combination with interference-proof +/- 15V CMOS similar to tax and regulation circuit technology, with processor control and monitoring
• Parallel final resonant circuit, thereby large efficiency of the static frequency inverter >90%
• Simple handling and operation
• Connection at three-phase alternating current without zero-leaders
