FAT M

A special type of inverter is systems for powering asynchronous motors – FAT. These inverters are characterised by frequency control of motor speed and control of motor faults.

ASK ABOUT THE PRODUCT

Product description

FAT M are drive inverters made as a 19″ module. They are adapted for mounting in 19″ industrial cabinets. The inverters operate on-line. They are dedicated to operating on sites that require a high reliability power supply for asynchronous motors. As the FAT M modules can be supplied with DC voltage from the DC switchgear, they are used to power, for example, emergency pumps in power and heating plants.

Ask about the product

The application of the FAT system brings the following benefits:

ensuring the uninterruptible operation of system-critical equipment that is sensitive to power failures and whose disconnection (caused by a mains power failure) could result in significant material damage
optimisation of the system’s operating parameters by adjusting the engine speed (power) – possibility of reducing the energy demand under certain operating conditions
providing a soft start for the motor – reducing the current surges in the motor supply circuits while reducing the shock torques on the motor shaft
