Frequency Inverters

Frequency inverters are devices designed for the smooth control of speed, torque, and acceleration of asynchronous AC motors. Advanced control functions also allow drive operation in synchronization and positioning applications. Together with geared motors, frequency inverters ensure high efficiency of the drive system and significant energy and material savings.

With years of experience and the use of modern technologies, Danfoss is a global leader in the field of controlled electric drives. Specialized application support, advanced control methods, and compact design ensure reliability, low installation costs, and the operation of the offered electric drive devices.

VLT HVAC Drive FC100

The VLT HVAC Drive series frequency inverters are designed for use in HVAC (heating, ventilation, and air conditioning) applications. They provide the best drive solution for powering and controlling pumps, fans, or compressors. They can operate as standalone units or be components of advanced building control systems (BMS).

VLT AQUA Drive FC200

The VLT AQUA Drive is a drive dedicated to powering and controlling pumps and blowers used in modern water and wastewater management systems. The wide power range, with standard and optional features offered by the VLT AQUA Drive, ensures the lowest investment and operating costs for electric drives.

VLT AutomationDrive FC300

The VLT AutomationDrive frequency inverters are designed for use in all industrial applications, from standard vector drives to servo drives. One drive type for the entire production line. A rich set of functions and many available additional options contribute to the universal nature of the drive.

VLT Micro Drive FC51

The VLT Micro Drive is a compact frequency inverter designed for all popular drive applications with asynchronous AC motors up to 22 kW. It provides good performance on the motor shaft, energy consumption optimization, and efficient operation of the drive system.

VLT 2800

The VLT 2800 series frequency inverters are compact multi-purpose drives primarily intended for tasks in the power range up to 18.5 kW. The small dimensions of the housing and the possibility of direct mounting side by side significantly save space in the control cabinet.

Soft starters

Soft Start Systems

Soft start systems, commonly known as soft starters, are devices designed to limit the current surges and mechanical stresses that occur when starting AC electric motors.

VLT Soft Starter MCD 100

The VLT Soft Starter MCD 100 is a compact and cost-effective soft starter used for starting AC motors with a power range from 1.1 to 11 kW. The MCD 100 provides voltage-based starting and stopping. Starting and braking times can be set in the range from 0.4 to 10 seconds.

VLT Compact Starter MCD 200

The VLT Compact Starter MCD 200 family includes two compact and highly functional models, MCD 201 and MCD 202, offered in the power range from 7.5 to 110 kW. They have 2 or 3-wire start/stop control and excellent starting capabilities (4 x Ie for 6 seconds). The starting time can be up to 20 seconds. Both models in the power range up to 30 kW can be mounted on a standard DIN rail.

VLT Soft Starter MCD 500

The MCD 500 Soft Starter is the most technologically advanced soft starter available in the Danfoss product range. It features high functionality and rich application and protective functions. Motor current control is carried out in all three phases, allowing for precise starting control and continuous monitoring of the parameters of the driven drive.
