Because the key part of the frequency converter is a monolithic micro-computer,it works erriciently: Protection of overcurrent,short-circuit,overvoitage,undervod-tage,instant power-off and phase. Display of frequency speed and load with digital or pointer. Designation of technology curve or speed by time. Frequency converter of the board is selected form JAPAN's FUJI os SANKEN components or by user,Ammeter, voltammeter,auto-airs-witch,indicating lamp and AC contactor are incuded.Operation mode could be besigned according to suer's technology requirement.
