SPX650A0-4A2N1

The Eaton Cutler-Hammer SPX650A0-4A2N1 drive is a variable frequency AC drive from the SPX9000 Series of AC drives. This powerful industrial device features ratings of 650 Horsepower of output power, 380 to 500 Volts AC input voltage, 0 to 320 Hertz maximum output frequency, a frame 12 housing, and 920 Amps of output current. The SPX650A0-4A2N1 drive operates with heavy-duty AC induction motors, and it has techniques to efficiently run these motors with reference speed and to limit torque in a situation where a consistent current to torque relationship is not established. This sophisticated drive implements the SPX sensorless vector control that makes mathematical motor models in order to accurately control the speed and torque or to limit the torque. This drive performs extremely well even in situations where users will expect strange situations from the gearbox and significant torque changes.

The Eaton SPX650A0-4A2N1 adjustable frequency AC drive is delivered in an open housing, and the users should additionally protect it from arcing by preventing foreign substances and metal parts from entering the drive’s enclosure. When performing maintenance on the device, the internal parts should not be touched immediately after the power supply disconnection because the capacitors within the drive remain at a hazardous voltage charge level for several minutes. The SPX650A0-4A2N1 drive is a modular motor speed controller that accepts up to 5 optional cards that can increase the functionality of the drive. The drive enables the monitoring of 3 preselected parameters which are refreshed every 0.3 seconds. These parameters are the output and reference frequency, motor speed, torque, current, power, voltage, DC bus voltage, heatsink temperature, and the calculated motor temperature parameters.
