Danfoss VLT® HVAC Drive AutomationDrive frequency converters

Danfoss VLT® HVAC Drive AutomationDrive frequency converters are designed specifically for heating, ventilation, and air - conditioning (HVAC) applications. Here is an introduction:

Features

High Energy Efficiency: The automatic energy - optimization function can save 5% - 15% of energy. It works efficiently at ambient temperatures up to 50 °C without output reduction, eliminating the need for external cooling or oversizing.

Compact Design: With a compact structure and an efficient thermal - control system, it is suitable for applications where space for frequency converters is limited.

Easy to Use: The integrated smart - start assistant guides users through the commissioning process in easy - to - understand language, reducing commissioning time. The operating concept is the same for all drives from 1.1 to 1400 kW, making programming easy.

Function-Rich: It has built - in intelligence and numerous functions developed specifically for pumps, fans, and compressors. It also has various safety functions, such as safe torque off and safe maximum speed, to protect systems and operating personnel.

Good Compatibility: The standard EMC filters ensure compliance with IEC 61800 - 3 category C1 (living area) with a 50 - m motor cable. The wide range of HVAC protocols allows easy connection to various building - management systems, and the built-in NABERS-compatible energy meter reduces the need for external energy meters.

Common Models

VLT® HVAC Drive FC 101: It is a basic - drive model suitable for some simple HVAC applications. It has a relatively wide voltage - input range, including 3×200 - 240V AC, 3×380 - 480V AC, and 3×525 - 600V AC. It can meet the basic control requirements of fans and pumps in HVAC systems and has functions such as energy saving and easy operation.

VLT® HVAC Drive FC 102: It is an intelligent - drive model with a power range of 0.75 - 250 kW. It has more advanced functions than FC 101, such as better - process control, a modular design, and rich expansion options. It can be easily connected to different building - management systems and is suitable for various complex HVAC system applications.
