Danfoss FC-202P37KT4E20H2 FC202 VLT AutomationDrive frequency converters

Here is a technical parameter introduction of Danfoss FC-202P37KT4E20H2:

General Information

Model: FC-202P37KT4E20H2

Series: VLT® AquaDrive FC202. This series is designed for water - related applications such as water supply and sewage treatment, aiming to provide efficient and reliable motor control solutions.

Power-related Parameters

Rated Power: The "P37K" indicates a rated power of 37 kW, suitable for driving a 37 - kilowatt motor, which is commonly used in medium - to - large - scale water - related equipment.

Input Voltage: It operates with a three - phase input voltage in the range of 380 - 480 VAC, which is compatible with different industrial power supplies.

Output Current: The rated output current is approximately 70 A (varies by specific model and voltage), ensuring a stable 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 environment with a maximum ambient temperature of 40°C without derating.

Enclosure and Protection: "E20" indicates an IP20 enclosure rating, providing basic protection against solid objects and dust. It is suitable for indoor installation in a relatively clean environment.

Humidity: It can work in an environment with a relative humidity of up to 95% non - condensing.

Control and Functionality

Control Modes: The drive supports various control modes, including V/F control, sensorless vector control, and closed - loop vector control, offering flexible motor control for different application requirements.

PI Controller: It is equipped with an automatically - tuned PI controller, which can monitor and adjust the system operation in real - time to effectively prevent water hammer phenomena and protect equipment and pipelines in the water system.

Flow Compensation Function: The flow compensation function can reduce the pressure setpoint according to the flow rate, thus saving energy during operation.

Multi - pump Control: The built - in multi - pump control function can control up to three pumps, including variable - frequency pumps, enhancing the overall efficiency and reliability of water supply and sewage treatment systems.

Communication and Interface

Communication Protocols: It supports communication protocols such as Modbus RTU, Profibus DP, and CANopen, enabling seamless integration with other industrial devices and control systems for remote monitoring and control.

I/O Interfaces: The drive is equipped with various digital and analog input/output interfaces, which can be used to connect external sensors, switches, and other control devices to achieve more complex control functions.

Safety and Protection

Over-current Protection: The drive has built-in over-current protection to prevent damage to the drive and the motor in case of excessive current.

Over-voltage and Under-voltage Protection: It can detect over-voltage and under-voltage conditions in the power supply and take appropriate protective measures to ensure stable operation.

Over-temperature Protection: The drive monitors its own temperature and the temperature of power components. If the temperature exceeds the safe limit, it will reduce the output power or shut down to prevent damage.
