Danfoss FC-202P55KT4E20H2 FC202 VLT AutomationDrive frequency converters

Here is the technical parameter introduction of Danfoss FC-202P55KT4E20H2:

General Information

Model: FC-202P55KT4E20H2

Series: VLT® AquaDrive FC202, designed specifically for water - related applications such as water supply systems, wastewater treatment plants, and other industrial processes involving water management.

Power - related Parameters

Rated Power: The "P55K" in the model indicates a rated power of 55 kW. This makes the drive suitable for driving high - power motors commonly used in large - scale water - related equipment.

Input Voltage: It operates with a three - phase input voltage in the range of 380 - 480 VAC. This wide voltage range allows the drive to be used in various industrial settings with different power supply voltages.

Output Current: The rated output current is approximately 103 A (varies depending on the specific model and input voltage). This ensures a stable and sufficient power supply to the connected motor.

Temperature and Environmental Parameters

Temperature Class: "T4" represents the temperature class. The drive is designed to operate in an ambient temperature of up to 40°C without the need for derating. This ensures reliable operation in typical industrial environments.

Enclosure and Protection: "E20" indicates an IP20 enclosure rating. This provides basic protection against solid objects and dust, making it suitable for indoor installation in relatively clean environments.

Humidity: The drive can function in an environment with a relative humidity of up to 95% non - condensing. This allows it to operate in environments with high humidity levels commonly found in water - related applications.

Control and Functionality

Control Modes: The drive supports multiple advanced control modes, including V/F control, which provides a simple and effective way to control the motor speed; sensorless vector control, which offers better torque control and dynamic performance without the need for additional sensors; and closed - loop vector control, which provides the highest level of accuracy and performance for applications requiring precise speed and torque control.

PI Controller: It is equipped with an automatically - tuned PI controller. This controller continuously monitors and adjusts the system parameters in real - time to maintain stable operation and prevent issues such as water hammer, which can cause damage to the pipes and equipment in a water system.

Flow Compensation Function: The flow compensation function is a key feature of the FC - 202. It allows the drive to adjust the pressure setpoint based on the actual flow rate in the system. This helps to optimize energy consumption, especially in variable - flow applications where the demand for water varies over time.

Multi - pump Control: The built - in multi - pump control function enables the drive to manage up to three pumps, including variable - frequency pumps. This allows for efficient operation of multiple pumps in parallel, improving the overall reliability and energy - efficiency of the water system.

Communication and Interface

Communication Protocols: The drive supports a variety of standard communication protocols, including Modbus RTU, Profibus DP, and CANopen. These protocols enable seamless integration with other industrial automation devices and control systems, allowing for remote monitoring and control of the drive.

I/O Interfaces: It is equipped with a comprehensive set of digital and analog input/output interfaces. These interfaces can be used to connect external sensors, such as pressure sensors, flow meters, and level sensors, as well as control signals from other devices, enabling the drive to interact with the surrounding equipment and perform complex control tasks.
