1. Constant power output and fast melting speed: IGBT intermediate frequency is a kind of power source with real constant power output. The inverter step rate keeps track of load changes, achieves complete resonance and maintains constant power output, so the melting speed is fast.
2. Energy-saving: Since the inverter part adopts IGBT half-bridge inverter, the inverter voltage is high, which is 30% more energy-efficient than ordinary thyristor power supply.
3. No high-order harmonic interference: Because the IGBT intermediate frequency adopts three-phase full-wave rectification, there is no phase sequence, no high-order harmonics are generated, and the power grid is not polluted.
4, 100% start: due to the use of serial inverter technology, so easy to start, can achieve 100% start.
