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 solution for small to medium applications is characterized by:

• Friendly parameterization through flexible control unit with digital potentiometer.
• Energy saving via OEC function.
• Multiple self-diagnostics to prevent failure.
• Controlled slowing down during brief power outages.
• Emergency stop and auto-tuning functions.
• Password protection and parameterization via PC software.
• Remote I/O and other advanced features.

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 inverter placement:

• Energy savings, as the fan does not operate continuously at full power.
• Increased lifespan of the fan with controlled operating conditions.
• Full control and protection against overvoltage, undervoltage, overload, and overheating.
• Effective noise prevention through Soft-PWM operation.
• Smooth starting and stopping of the fan with adjustable time.
• Speed adjustment with built-in potentiometer or automation.
