Cut your electricity bill by 10–20%. The most energy-efficient power supply for induction melting — featuring Infineon IGBT modules, PLC control, and built-in protection.
Older SCR power supplies waste 10–20% more energy per ton of metal melted. At high production volumes, this waste adds up to tens of thousands of dollars annually.
Inadequate protection circuits lead to IGBT or SCR failures that shut down your entire furnace line — often at the worst possible time.
Low power factor (0.75–0.85 in older systems) triggers reactive power penalties from your utility. A 0.95+ power factor eliminates these extra charges.
Generic or unknown-brand IGBT modules are impossible to source quickly. Each day of downtime costs thousands in lost production.
The YuRun IGBT Medium Frequency Power Supply is the heart of a modern induction melting system. Built with Infineon (Germany) or Fuji (Japan) IGBT modules — the same brands used in European industrial equipment — it delivers reliable, efficient power from 50kW to 3000kW with automatic frequency tracking from 100Hz to 2500Hz.
Unlike SCR power supplies that require external reactive power compensation and protection circuits, IGBT technology provides built-in self-shutoff protection against overcurrent, overvoltage, and overtemperature. The result is fewer components, fewer failure points, and significantly lower maintenance costs over the furnace's operating life.
IGBT inverter technology achieves conversion efficiency of 95%+. In real-world production, this means 480–560 kWh per ton of steel vs 580–650 kWh for SCR furnaces — a direct electricity cost reduction.
IGBT modules have built-in gate driver protection circuits that respond in microseconds to overcurrent events — far faster than external fuse or relay protection. No separate protection cabinet required.
As furnace load changes during melting (solid → liquid → pouring temperature), the inverter automatically adjusts frequency to maintain maximum power transfer. No manual frequency adjustment needed.
Power ramps up gradually over 2–5 seconds instead of slamming full power onto the grid. Eliminates voltage spikes that trip circuit breakers and protects induction coil insulation from thermal shock.
Siemens or Mitsubishi PLC records production data, fault codes, and operating hours. Export data via USB for production management or remote diagnosis by our engineers via TeamViewer.
IGBT modules are plug-in replaceable. If a module fails, a trained technician can swap it in 30–60 minutes. Infineon and Fuji modules are available worldwide from authorized distributors.
