Medium Frequency Induction Heating Machine
The JLZ medium-frequency series is the workhorse power supply for through heating, forging and many melting packages. Catalogue output runs from 15 kW to 600 kW on three-phase 380 V, 50/60 Hz. Smaller sets sit around 1–20 kHz. Larger sets move toward 0.5–10 kHz. IGBT inverter sections run in parallel. The catalogue design is for continuous duty, with water cooling and protection against over-voltage, over-current and water failure. Use this page for the power supply. Use the melting and forging pages when you need kilograms per heat or kilograms per minute.
