VFD units S1100-4t15G Frequency Inverter 380V | Three phase | 15KW
A Variable Frequency Drive (VFD) is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the electric motor. Other names for a VFD are variable speed drive, adjustable speed drive, adjustable frequency drive, AC drive, microdrive, and inverter.
FEATURES:
- Professionally customised core computing program.
- Smooth shift on forward and reverse rotation.
- Automatic torque compensation.
- Automatic slip compensation.
- Advanced control technology of switching 3-phase to 2-phase, reduces heat by 33.3o/o.
- Adopting nanometer manufacturing technology.
- CPU with built-in dual core dramatically improves the computing speed.
Reliability
- Protect function: over voltage(OU), low voltage(LU), over current(OC), over heat(OH), over load(OL).
- Over voltage and over current stall prevention.
- The technology of integration hardware and software wave filtering for better anti-jamming effects.
- 3-level prohibited frequencies can avoid resonance effectively.
- Braking using software control,be able to adjust brake-bit and brake occupating coefficient.
High Performance
- Automatic torque compensation-start torque can be up to 150% at 2HZ.
- Automatic slip compensation-more accurate speed.
