Toshiba VFAS3-4110KPC

One high-performance and adaptable adjustable speed drive (ASD) in Toshiba's AS3 series is the VFAS3-4110KPC. This drive incorporates state-of-the-art features and standards to cater to the rigorous requirements of different industries, making it ideal for demanding industrial applications. The VFAS3-4110KPC is a great option for managing motor speed and torque in important operations since it is efficient, has complete safety features, and is adaptable.

Technical Specifications:

Toshiba VFAS3-4110KPC input voltage is 460 VAC, and the output voltage is equally divided over three phases. It can handle loads up to 150% overload for 60 seconds in heavy-duty mode and 200 HP in normal-duty mode with 120% overload. Two power ratings are available. The drive's versatility lets it handle various loads.

The VFAS3-4110KPC works with several motor speeds because of its 0.1 to 400 Hz frequency range. It uses little power and has a 95% efficiency rating. Adjusting the output current from 250 A for normal duty to 211 A for heavy duty meets many industrial demands.

Built-in two-wire/four-wire RS485 interfaces and dual-port Ethernet IP make the VFAS3-4110KPC easy to connect to modern industrial networks. Its built-in web server lets you monitor and control drive operations from anywhere. This feature simplifies quick changes and boosts efficiency.

Eight programmable digital inputs let you design the drive for different control methods. Three digital outputs can be set to indicate operating conditions or faults. These outputs contain one Form-C and two Form-A dry contact relays. Three programmable analog inputs (4-20mA, 0-10 VDC, and +10 VDC) and two programmable analog outputs (4-20mA or 0-10 VDC) increase their adaptability to diverse sensors and control systems.

Safety and Additional Features:

The VFAS3-4110KPC was designed with safety as its first priority. It meets the requirements of IEC 61800-5-2 and obtains a SIL 3 rating according to IEC 61508, and it has an integrated Safe Torque Off (STO) terminal. In order to safeguard the equipment and staff, this feature guarantees that the drive can be securely turned off without power cycling.

In addition, the real-time clock is a standout feature that helps track previous trips and use the calendar to record operational occurrences in the past accurately. Both predictive maintenance and troubleshooting benefit from this. The drive's QR code display makes it easy to access parameter information and fix faults, which improves maintenance ease and reduces downtime.

Physical Characteristics and Compliance:

The VFAS3-4110KPC is physically 33.5 inches tall, 11.8 inches wide, and 15.1 inches deep, making it suitable for typical industrial settings. Most industrial systems can handle its modest weight of about 219 lbs. The drive meets all established safety criteria since it is UL-approved (file number E204788). Thanks to its effective forced air cooling system, it can withstand large loads without overheating.
