In Factory Industries, Hotels, Hospitals There are equipment that uses Induction Motor for general and heavy duty applications Among them are Pumps, Compressors, Fan, Blowers, Conveyors, and other production process drivers. For the process it takes a low speed and initial torque setting for gar according to needs. To overcome this problem, the control system can be used by adjusting the input voltage and frequency namely VSD (Variable Speed Drive) / VFD (Variable Speed Drive) Inverter thus getting speed and torque settings according to the needs of the production process in Industry, Hotels, Hospitals Slanvert Inverters have obtained ISO9001: 2008, ISO14001 and CE certification Available from 3 phase 380-400 V with a power of 0.4 - 1650KW
