The Eaton Cutler-Hammer SPX 9000 series drives are variable frequency drives (VFDs) engineered for applications in demanding industrial environments. They control industrial motors and are available with different ratings and features for operating with different kinds of motors. Some SPX 9000 drives come with internal brake choppers, and some come with optional extended I/O cards or communication cards. When the SPX 9000 drives are installed, they can be stacked vertically or mounted side by side.
The SPX 9000 drives operate with AC input voltage. Drives that operate at 208 to 240V AC, 380 to 500V AC, or 525 to 690V AC are available in this series, and each drive can tolerate -15% to +10% voltage fluctuation during operation. SPX 9000 drives typically operate at 50 or 60 Hertz of rated frequency, but they can tolerate frequency variations between 45 and 66 Hertz. The maximum symmetrical supply current ratings for the SPX 9000 drives are 100 kAIC at 208 to 240V AC, 380 to 500V AC, and 525 to 690V AC. These drives support output voltage ranges between 0V and their rated input voltage. The SPX 9000 drives come with closed loop control technology and open loop sensorless vector control technology. They support acceleration and deceleration times between 0.1 and 3000 seconds.
The SPX 9000 series drives can support enclosure ratings of IP21 or IP54. These drives can operate at ambient temperatures between 14 and 122 degrees Fahrenheit or 14 and 104 degrees Fahrenheit in environments with no frost or freezing conditions. The SPX 9000 drives can be stored at ambient temperatures between -40 and 158 degrees Fahrenheit. Their protection features include overcurrent protection, overtemperature protection, undervoltage protection, and short circuit protection. The SPX 9000 drives also include protective features for the connected motor, such as the motor overload protection, motor underload protection, and motor stall protection features. These features reduce downtime and system errors in the drives and the motors.
