Single-phase input (1˜200-240 Vac): 0.1 / 0.2 / 0.4 / 0.75 / 1.5 & 2.2 kW. Three-phase input (3˜380 Vac): 0.75 / 1.5 / 2.2 / 3.7 / 5.5 & 7.5 kW. The flexible and practical solution for small to medium applications.

• User-friendly configuration with a flexible control unit using a digital potentiometer.
• Energy saving through a special OEC function.
• Prevents faults with multiple self-diagnostics.
• Advanced features such as:
  • Controlled deceleration during brief power losses,
  • emergency stop,
  • auto-tuning even with the motor stopped in less than a minute,
  • password protection mode,
  • configuration via software with a PC,
  • remote I/O and many others.
• Control methods: General purpose magnetic Flux Vector & Optimum excitation.
• Overload capacity: 150% for 60 sec (1Hz), 200% for 0.5 sec (from 3Hz).
• Advantages of installing an INVERTER:
  • Energy savings,
  • Extended lifespan of the fan,
  • Full control & protection of the fan from overvoltage, overcurrent, undervoltage, overload, overheating, ground fault & connection errors, short circuit.
• Reduces noise & prevents the creation of annoying humming and buzzing sounds with Soft-PWM operation.
• Smooth start and stop of the fan with adjustable time or/& preset speeds.
• Speed adjustment using an integrated potentiometer or through automation of the working conditions via special sensors.
• Standardized according to all international standards CE, UL, CUL, EN (LVD) & compliant with ROHS Directive for inverter friendliness to humans & the environment.
