Toshiba VF-AS3 inverters

Toshiba VF-AS3 inverters
Inverters are the "beating heart" of modern automation. Their primary function is to convert the fixed electrical current from the power supply into a variable current, allowing precise control of electric motor speed and torque. In extraction systems, the inverter is not simply an electrical component, but the true "director" of energy savings and mechanical protection.
In an extraction system, the workload is not always constant. Using a Toshiba VF-S15 or VF-AS3 inverter allows the system to move from an "always running at maximum capacity" approach to an intelligent and adjustable solution.
The VF-AS3 inverter represents the top-of-the-range model in the Toshiba inverter family. It is an intelligent inverter designed for Industry 4.0 applications, capable of managing complex systems and heavy-duty loads with exceptional precision.
  • Constant pressure control: manages duct pressure sensors to automatically increase or decrease the extraction unit speed according to the number of suction points opened or closed.
  • Motor protection: continuously monitors the extraction unit workload. If it detects clogged filters or blocked ductwork, it intervenes to prevent overheating or motor failure.
  • Remote monitoring: allows filter status and energy consumption to be monitored directly through the company management system or network, simplifying scheduled maintenance.
  • Complete connectivity: supports advanced communication protocols (such as Ethernet and Ethernet/IP), enabling remote monitoring of machine operation.
  • Harmonic suppression: thanks to its integrated high-performance filter, it reduces electrical disturbances on the power network, protecting other electronic components inside the control panel.
  • Integrated Web Server: provides access to operating data, diagnostics, and predictive maintenance information directly through a web browser, without requiring dedicated software.
  • Advanced motor control: smoothly manages both traditional induction motors and modern permanent magnet motors, delivering extremely high torque even at very low speeds.
Installing Toshiba inverters in electrical control panels means guaranteeing the end customer:
  1. Reliability: reduced risk of unexpected system downtime.
  2. Efficiency: reduced mechanical wear thanks to smooth motor starts and stops.
  3. Long-term value: use of globally recognized Japanese components known for their strength and durability.
  4. Energy savings: significantly lower electricity consumption compared to a motor connected directly to the power supply (direct-on-line starting).
  5. Reduced maintenance: fewer vibrations and belt shock loads mean fewer repair interventions.
  6. Compliance: systems ready for energy efficiency regulations and Industry 4.0 requirements.
