INDUCTION GENERATOR PFG25K25S3

Compact Induction generator PFG25K25S3 is purposed for wide need in metal industry. For induction hardening, forging, welding of different metals or of diamonds on blades and thermally shrinking tools and of machine parts.

Characteristics and advantages

• Compact design and small dimensions of the generators with separate output transformer with capacitor battery and connection for a quick change off inductors
• Separate heating unit with inductor, connected to Generator due flexible leads length to 5m, for easier access to appliance or automatically serving plant.
• Aluminum casing of the generator and the output part
• Small Weight of the whole unit
• Output Power regulation from 6 to 100% with step per 2%
• 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 protection of the power semiconductors
• Adjustment possibility of two-time intervals -timers from (T1+T2 -2 x 25,5s, P-from 6 to 100%) or (T1+T2 -2 x 255s) with adjustment of two output power levels in sequence.
• LCD display with error memory diagnostics
• Large load adjustment and resonance frequency of the output circuit
• The most modern Power IGBT technology in combination with reliable analog +/- 15V CMOS regulation circuit technology controlled with processor unit
• 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
