The 3G SmartVFD is the 3rd generation of SmartVFD variable frequency drives designed specifically for use in HVAC applications. Designed to control any HVAC pump or fan application to maximize system reliability and energy efficiency. SmartVFD will efficiently operate 3-phase induction, permanent magnet, and high-efficiency synchronous reluctance motors.

The 3G SmartVFDs for HVAC is easy to install, communicates effectively with building control systems to minimize energy consumption.

• Start-up Wizards—SmartStart and Automatic Motor Adaptation make commissioning easy for all motor types, enter nominal information and let the drive measure motor characteristics to optimize performance.
• Graphic Interface—Using the graphical keypad makes navigating parameters easy. INFO key provides easy access to help information in the onboard manual. BACK and OK buttons simplify programming.
• Embedded Communications—Standard BACnet, Modbus, FLN and N2 allow monitoring and control of serial communications, reducing installation cost.
• Dedicated for HVAC—The 3G SmartVFD includes intelligent functions for pumps fans and compressors.
• Built-in logic—Smart logic controller and four auto-tuning PID controllers can control HVAC functions reducing the need for control tasks in the building management system.
• DC-link reactor ensures low harmonic disturbance of the power supply
• Fire override mode for continued operation for essential services
• Enclosure classes NEMA 1 or NEMA 12
• Built-in protection, Overvoltage trip and undervoltage trip protection, Ground fault protection, Mains and motor phase supervisions, Overcurrent and unit overtemperature protection, Motor overload, motor stall and motor underload protection, Short-circuit protection of +24V and +10V reference voltage
