ST9400 Powerful Frequency Inverters

The ST9400 series of frequency inverters is designed for high power and high performance applications. These drives are available in a variety power classes. You have the following choices: 45 KW55 KW75 KW93 KW110 KW132 KW160 KW187 KW200 KW and 220 KW.

All frequency inverters from the ST9400 series operate at three-phase 400V. They can also be custom built for other voltage classes like 690V or 500V. Due to their great performance, they can be reliably used with motors for professional applications. These frequency inverters are resistant to overloads, and can handle excessive loads of 150% for as long as one minute, and 180% for up to 2 seconds. The commissioning of these drives is very easy thanks to their intuitive and simple operation, the default pre-configuration, and the plug and play installation. Thus, you can have them fully operational in a very short while. They have large knobs that let you effortlessly adjust various parameters like voltage, current, frequency, PID, and torque. All values are shown clearly on a large digital display. The controls can also be detached, allowing you to operate them remotely over a network using a LAN cable.

The ST9400 variable-frequency drives can be housed in three different cabinet variants.

In addition, the frequency inverters have a wide range of accessories such as resistors, an EMV Filter, and an RS485 interface. The programs, ST® Drive, ST®A PP 1.1, and ST® DLV 1.0 can be chosen as well.
