VLT® HVAC Drive is designed to provide optimized process control for various heating, ventilation and air conditioning (HVAC) applications. The inverter has a built-in intelligent system, which is simple to use, convenient and quick to debug and cost-effective. At the same time, it has the ability to control multiple high-efficiency permanent magnet synchronous motors in parallel. In addition, it also has a wide range of functions developed specifically for pumps, fans and compressors, so as to comply with environmental regulations to save energy and reduce modern building costs.
    VLT® HVAC Drive has a compact structure and an efficient thermal management system, which is especially suitable for applications with limited installation space. A series of selected safety features, such as Safe Torque Off and Safe Maximum Speed, ensure the safety of applications and operators at the same time.
    The inverter is sturdy and durable, and can run without failure even in harsh environments, ensuring normal operating time. The enclosure protection level can be as high as IP 66 (depending on the model). Provide options with special coatings to strengthen the protection of the circuit board. The built-in DC reactor and radio frequency interference filter protect the installed equipment by reducing harmonic distortion and electromagnetic interference.

Features and advantages
    The maximum ambient temperature is 50°C, no capacity reduction, no need to add external cooling equipment or expand heat dissipation space, and benefit from the intelligent logic controller, no need to use the PLC modular design concept and rich options, which is the initial investment reduction and easy The upgrade is equipped with the control functions of pumps, fans and compressors, without external control or conversion device with automatic energy efficiency optimization function, which can save 5-15% of energy. It conforms to a variety of HVAC protocols suitable for the connection of building management system controllers, reducing Demand for gateway solutions EMC solutions comply with IEC61800-3 category C1 (housing), 50 meters of motor cable standards, so no external filter is required. The C1 standard can save debugging time by correctly connecting the motor cable and the motor terminal to complete the built-in intelligent start-up wizard, and guide the user to complete the setting process in a simple and easy-to-understand language. The user interface of 1.1-1400kW products is exactly the same, understanding one is equivalent to understanding All, setting a 1.4MW inverter is as simple as setting a 3kW inverter. Built-in NABERS compatible energy meter reduces the need for external energy meters. VLT® HVAC Drive FC 102 provides free common fieldbus Modbus and BTL BACnet in the list. BACnet allows the inverter to be quickly integrated into the building management system. It can read and share data points, and can input and output actual values and required values in the system
