Danfoss VLT AutomationDrive frequency converters

VLT® AutomationDrive takes full advantage of all that the new digital age has to offer to ensure it completely fulfills the requirements of your applications and optimizes your processes throughout the entire lifecycle.

Its cutting-edge thermal design and unique back-channel cooling make VLT® AutomationDrive one of the most compact and cost-efficient drives in the market. Intelligent maintenance and monitoring functions improve the productivity, performance, and uptime of your systems in the long term.

Danfoss VLT AutomationDrive is a series of high-performance frequency converters designed for industrial automation applications. Here is a detailed introduction:

Features

High reliability: The circuit boards are coated with anti - corrosion materials, enabling them to adapt to corrosive environments. Removable fans facilitate quick cleaning and replacement. Built - in DC reactors and filters can reduce harmonics and meet EMC requirements. The unique heat management system prevents dust and oil from accumulating on the pins, reducing the risk of short - circuits.

Easy to use: It has a digital panel with a brighter LCD, better - tactile buttons, and an added left - right movement button. It allows for side - by - side installation, saving cabinet space. With application macro selection, it automatically loads the empirical values of relevant parameters, which simplifies the debugging time for users. The dual - component design allows for the quick replacement of vulnerable parts without the need for professionals.

Function-rich: It offers optional bus connections such as PROFIBUS and PROFINET to match the most advanced upper - level automation systems. The 0.37 - 22 kw models can drive permanent - magnet synchronous motors, improving motor efficiency. It also provides free PID control with feed - forward, which is suitable for constant - speed and constant - tension loads. In addition, the advanced model has functions such as PLC, automatic fine - tuning of motor control, and self - analysis of performance.

Common Models of Danfoss VLT

VLT® AutomationDrive FC360: The product line range is 3x380-480V, 0.37-75kW. It has the advantages of high reliability, easy use, and rich functions. For example, it has a built - in DC reactor that can reduce the harmonics of the frequency converter to within 43%, and a built - in RFI filter that meets the C3 level standard of EN61800 - 3.

VLT® AutomationDrive FC302: The power range is 0.25kW-1.4MW, and the voltage range is 220V - 690V. It adopts a frequency - converter - control concept that can control all operations from standard to servo control on any machine or production line. It has functions such as PLC, automatic fine-tuning of motor control, and self - analysis of performance, and can also perform high - precision positioning and synchronization operations.

VLT® AquaDrive FC202: It is a frequency converter designed specifically for water supply and sewage treatment applications. It has powerful standard and optional functions, such as pipe - filling mode, broken - pipe and leakage detection, empty - pump protection, motor alternation, and flow compensation, which can minimize the total cost of ownership in water supply and sewage treatment applications.

VLT® HVAC Drive: It is designed based on Danfoss's new modular plug-and-play platform and is specifically positioned for HVAC applications. It makes HVAC operations easy and is an ideal product for advanced building HVAC facilities such as pumps, fans, and water coolers (compressors).

VLT® OneGearDrive®: It is a high-efficiency permanent - magnet three - phase synchronous motor coupled with an optimized bevel-gear box. There are two types of frequency converters: standard type and hygienic type. The system has high efficiency and can save up to 40% of energy compared with traditional systems.

Application Areas

Danfoss VLT frequency converters are widely used in various industries such as pharmaceuticals, textiles, chemicals, food, water treatment, and building automation. For example, in the food and beverage industry, the VLT® FlexConcept® frequency-converter system is used to improve the productivity and energy efficiency of bottling production lines. In the water treatment industry, the VLT® AquaDrive FC202 is used to control pumps, which can prevent water hammers, detect pipe breaks and leaks, and save energy.
