22KW 400V three-phase inverter EU UMI-0220EE-B1

22kW Three-phase Inverter – Precise Control and Efficiency

This advanced inverter, with a power of 22kW and a 400V supply, is the heart of the motor control system. Designed for both industrial applications and more demanding installations, it offers reliable operation and a wide range of functionalities. It is an ideal solution for installers looking for an efficient and versatile device, as well as end-users expecting precise control over drive operation.

Versatility and Functionality

The inverter allows smooth speed control of three-phase motors, which translates to process optimization and energy savings. Available control modes – vector and scalar – allow you to adapt the operating parameters to the specifics of the application. Built-in safety functions, such as Safe Torque Off (STO), guarantee protection for both the machine and the operator. Thanks to the ability to program the inverter, it can be adapted to individual needs, and the built-in PID controller allows for precise maintenance of process parameters.

Design and Application

The device is characterized by a solid construction and compact dimensions, which facilitates installation in control cabinets or directly on the wall. The built-in EMC filter of category C3 minimizes electromagnetic interference, ensuring compatibility with other devices in the installation. An optional EMC filter of category C2 further improves interference immunity. The inverter complies with IEC 61800-3, which confirms its safety and reliability. The ability to separate the control panel (from 4kW) increases installation flexibility.

• Wide input voltage range: the device operates in the range of 380V (-15%) – 440V (+10%), with a rated voltage of 400V, ensuring compatibility with various power networks.
• High efficiency: the output rated current is 45.0A at 22kW, guaranteeing efficient energy use.
• Advanced control functions: vector control (SVC) and scalar U/f (SVPWM) modes are available, allowing precise adaptation of operating parameters to a specific application.
• Built-in protections: the device is equipped with protection against over/under voltage, overcurrent, and overheating, ensuring reliable operation.
• Communication: MODBUS RTU RS-485 communication enables integration with industrial automation systems.
• Installation flexibility: wall or DIN rail mounting simplifies installation in various conditions.
• EMC filter: the built-in EMC filter of category C3 reduces electromagnetic interference affecting other devices in the installation; the optional C2 filter provides even better protection against interference.
• PLC mode: allows programming the inverter to perform simple sequences of operations without the need for an external PLC controller.

Please remember the temperature limitations - optimal operation in the range of -10 to 40°C (above this temperature, the inverter power may be reduced). Altitude above sea level should also be considered – above 1000m, the inverter power may require correction.
