55KW 400V three-phase inverter EU UMI-0550EE-B1

55kW Three-Phase Inverter – Precise Drive Control

This advanced Unitronics UMI-0550EE-B1 inverter is the heart of efficient induction motor control. Designed to operate in demanding industrial conditions, it offers reliable operation and a wide range of configuration options. The device is intended for powering three-phase motors with a voltage of 400V and a power of up to 55kW, ensuring optimal performance and control over processes.

Flexible Control and Safe Operation

The UMI-B1 inverter offers two control modes – vector and scalar, allowing you to adapt the operating parameters to the specifics of the application. The built-in STO (Safe Torque Off) protection guarantees safe stopping of the torque, minimizing the risk of accidents. Additionally, the factory-installed EMC filter category C3 reduces electromagnetic interference, and the optional C2 filter provides even higher compatibility with other devices.

Construction and Industrial Applications

The inverter is designed to work with three-phase asynchronous motors, finding application in a wide spectrum of industrial applications. The ability to separate the control panel (from 4kW models upwards) facilitates installation and servicing of the device. Thanks to its compact dimensions (282 x 560 x 238 mm) and the possibility of wall or DIN rail mounting, the inverter can be easily integrated with existing infrastructure. The built-in DC choke (in models ≥18.5kW) further stabilizes the system operation.

Key features and benefits:

• High output power: 55kW allows for efficient powering of demanding industrial applications.
• Universal control: Two control modes (vector and scalar) provide flexibility in adapting to different loads.
• Safety: STO function and EMC filters protect both the device and the environment.
• Wide input voltage range: Accepts a supply voltage of 380V (-15%) – 440V (+10%), which increases resistance to voltage fluctuations in the network.
• Advanced communication functions: MODBUS communication support enables integration with automation and monitoring systems.
• Motor protection: Comprehensive protection functions against damage related to over/under voltage, current and overheating ensure long-term and trouble-free operation of the motor.
• Voltage stabilization: Automatic voltage stabilization maintains a constant value even with an unstable mains voltage.
• Wide operating temperature range: From -10°C to 50°C (taking into account derating above 40°C).

Thanks to TÜV SÜD certification, the inverter meets strict safety and quality standards, guaranteeing reliable operation for a long time. It is an ideal solution for professionals looking for an efficient and reliable inverter for demanding industrial applications.
