The three-phase Allen-Bradley 25A-E9P9N104 is a PowerFlex 523 AC-powered drive that uses a C frame size and which is equipped with a standard brake and interface module, but it does not have any EMC filter installed. It uses an IP20, NEMA open enclosure and it has a voltage rating of 600V AC. At an input that ranges from 525 to 600V, the 25A-E9P9N104 drive has a 9.9 A output current, and when the drive is used for both normal duty and for heavy-duty operations, it has output ratings of 5.5 kW and 7.5 HP each. Its voltage tolerance is -15% or 10% and it also has a frequency tolerance that ranges from 47 to 63 Hz. The output voltage of this drive ranges from 0 to the rated motor voltage of the drive and its programmable output frequency range is from 0 to 500 Hz.

Present on this drive are 6 programmable digital inputs, 1 digital input that is dedicated for stopping, 2 isolated analog inputs, 2 programmable relay outputs (Form A and Form B), 1 non-isolated analog output, and 2 programmable opto outputs. Various control options available for the 25A-E9P9N104 drive are volts per Hertz, sensorless vector control, sinusoidal PWM, and economizer SVC motor control. For protection, this drive has a bus Undervoltage trip of 487V DC bus (which is the same as a 344V AC incoming line), as well as a bus overvoltage trip of 1005V DC (equal to a 711V AC incoming line). The 25A-E9P9N104 also has an overcurrent protection that is 300% of the instantaneous fault and 200% of the hardware limit.
