Danfoss FC-202P90KT4E20H2 FC202 VLT AutomationDrive frequency converters

Here is the technical parameter introduction of Danfoss FC-202P90KT4E20H2 VLT® AquaDrive FC202:

General Information

Model: FC-202P90KT4E20H2

Series: It belongs to the VLT® AquaDrive FC202 series, which is designed specifically for water - related applications, such as water supply systems, wastewater treatment plants, etc. It provides reliable and efficient motor control solutions.

Power - related Parameters

Rated Power: The "P90K" in the model indicates a rated power of 90 kW, which is suitable for driving high - power motors 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 166 A (varies depending on the specific model and input voltage), ensuring 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, ensuring 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, which is suitable for the often - humid environments in water - related applications.

Control and Functionality

Control Modes: The drive supports multiple control modes, including V/F control, sensorless vector control, and closed - loop vector control, to meet different application requirements for motor speed and torque control.

PI Controller: It is equipped with an automatically - tuned PI controller. This controller can monitor and adjust system parameters in real - time to maintain stable operation of the water system, prevent issues such as water hammer, and protect system equipment.

Flow Compensation Function: The flow compensation function allows the drive to adjust the pressure setpoint according to the actual flow rate in the system. This helps optimize energy consumption, especially in variable - flow applications.

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

Communication and Interface

Communication Protocols: The drive supports standard communication protocols such as Modbus RTU, Profibus DP, and CANopen, facilitating seamless integration with other industrial automation devices and control systems for remote monitoring and control.

I/O Interfaces: It is equipped with a variety of digital and analog input/output interfaces, which can be connected to external sensors, switches, and other control devices to achieve complex control functions and system integration.
