Danfoss FC-202P30KT4E20H2 FC202 VLT AutomationDrive frequency converters

Technical Parameter Introduction of Danfoss FC-202P30KT4E20H2 VLT® AquaDrive FC202

1. General Information

Model: FC-202P30KT4E20H2

Series: VLT® AquaDrive FC202. This series is specifically engineered for applications in water supply, sewage treatment, and other water - related systems, aiming to provide efficient and reliable motor control solutions.

2. Power - related Parameters

Rated Power: The "P30K" indicates a rated power of 30 kW. This means the drive is capable of powering a 30 - kilowatt motor, making it suitable for medium - to - large - scale water - related equipment such as pumps and blowers.

Input Voltage: It is designed to operate with a three - phase input voltage in the range of 380 - 480 VAC. This wide voltage range allows for compatibility with different industrial power supplies.

Output Current: The rated output current is approximately 57 A, which ensures a stable power supply to the connected motor.

3. 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. However, if the ambient temperature exceeds this value, appropriate derating measures may be required.

Enclosure and Protection: The "E20" indicates an IP20 enclosure rating. This provides basic protection against solid objects (such as fingers) and dust, but it is not suitable for use in wet or dusty environments. It is typically intended for indoor installation in a relatively clean environment.

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

4. Control and Functionality

Control Modes: The drive supports various control modes, including V/F control, sensorless vector control, and closed - loop vector control. These modes provide flexibility in motor control, allowing for precise speed and torque regulation according to different application requirements.

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

Flow Compensation Function: The flow compensation function can reduce the pressure setpoint based on the flow rate, thereby saving energy during operation.

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

5. Communication and Interface

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

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

6. 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 the power components. If the temperature exceeds the safe limit, it will reduce the output power or shut down to prevent damage.
