Multi-Switch Inverter Panel (VIP)

Multi-switch induction inverter is a panel with one inverter that can be switched to multiple coils or zones by fast power electronic switches with high frequency This feature is used in processes that require accurate control of temperature in different zones of the melt or susceptor independently, such as the production processes of jet turbine blades, production of mono crystal silicon, etc.

Mehronic Company’s offering of Multi-Switch Induction Inverter panels spans a power range from 145 to 1500 kW.
