terima kasih untuk pertanyaan nya. saya coba jawab.
beban motor 7.5 kW bisa menggunakan kapasitas VSD diatas beban tersebut, dalal hal ini 11 kW.
pemilihan rating VSD ada beberapa pertimbangan :
1. power factor motor
- VSD akan mengkompensasi cos phi motor yang umumnya kurang bagus sehingga pada saat full load, output motor bisa sesuai dengan name plate.
2. kapasitas overload
- jika motor dipasang pada aplikasi hoist atau crane, biasanya membutuhkan arus start atau torsi yang besar di awal 150% - 170%. rating VSD diatas motor bisa mengkompensasi arus start tanpa harus terjadi trip karena overload atau over current.
