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.

Main features:

• Flexible and practical solution for small to medium applications.
• Easy parameterization through a flexible control unit with a digital potentiometer.
• Increased energy savings through a special OEC function.
• Multiple self-diagnostics to prevent failures.
• Advanced functions such as a) controlled deceleration during short power losses, b) emergency stop, c) auto-adjustment even with the motor stopped in less than a minute.
• Support for password-protected operation, parameterization via FR software with PC, and remote I/O.
• Control methods: General Purpose Magnetic Flux Vector & Optimal Excitation.
• Overload capacity: 150% for 60 sec (1Hz), 200% for 0.5 sec (from 3Hz).
• Advantages of installing an INVERTER:
  • Energy savings, as the fan does not operate continuously at full power.
  • Extended fan lifespan with controlled operating conditions.
  • Full control & protection of the fan against overvoltage, overcurrent, undervoltage, overload, overheating, etc.
  • Reduced noise & prevention of annoying buzzing-humming sounds with Soft-PWM operation.
  • Smooth start and stop of the fan with adjustable time or preset speeds.
• Speed adjustment via built-in potentiometer or automatic control through dedicated sensors.
• Standardized according to all international standards CE, UL, CUL, EN (LVD) & compliant with ROHS Directive for the inverter's friendliness towards humans & the environment.
