Danfoss FC-202P45KT4E20H2 FC202 VLT AutomationDrive frequency converters

Here is the technical parameter introduction of Danfoss FC-202P45KT4E20H2:

General Information

Model: FC-202P45KT4E20H2

Series: VLT® AquaDrive FC202, which is designed for water - related applications like water supply and wastewater treatment to offer efficient and reliable motor control.

Power-related Parameters

Rated Power: The "P45K" indicates a rated power of 45 kW, suitable for driving motors of this power level, commonly used in medium - to - large - sized water - related equipment.

Input Voltage: It operates with a three - phase input voltage ranging from 380 - 480 VAC, ensuring compatibility with various industrial power supplies.

Output Current: The rated output current is around 84 A (varies depending on the specific model and voltage), providing a stable power supply to the connected motor.

Temperature and Environmental Parameters

Temperature Class: "T4" means the drive is designed to work in an environment with a maximum ambient temperature of 40°C without derating.

Enclosure and Protection: "E20" represents an IP20 enclosure rating, offering basic protection against solid objects and dust, suitable for indoor use in clean environments.

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

Control and Functionality

Control Modes: The drive supports multiple control modes, including V/F control, sensorless vector control, and closed - loop vector control, providing flexible control options for different application needs.

PI Controller: It features an automatically - tuned PI controller that can monitor and adjust the system in real - time to prevent water hammer effects and protect the equipment and pipelines in the water system.

Flow Compensation Function: This function can adjust the pressure setpoint according to the flow rate, helping to save energy during operation.

Multi - pump Control: The built - in multi - pump control function allows for the control of up to three pumps, including variable - frequency pumps, improving the overall efficiency and reliability of water - related systems.

Communication and Interface

Communication Protocols: It supports 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 connected to 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 safeguard the drive and motor from damage caused by excessive current.

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

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