The Allen-Bradley 25B-E012N104 is an electronic device that functions as a Variable Frequency Drive (VFD) or Variable Speed Drive (VSD). It is part of the PowerFlex 525 product family that is used to control the Speed or Torque of an AC motor. It is supplied by an input voltage of 446-660 VAC, 3-Phase and converts this to a Pulse Width Modulated (PWM) output, in the form of 0-575 VAC, 3-Phase along a motor applicable output current of 12.0 Amperes, 10 Horsepower or 7.5 kiloWatts. It also provides a fully programmable output frequency of 0-500 Hz. To implement modulating control, the 25B-E012N104 is capable of implementing a variety of control methods including Sinusoidal PWM, Volts/Hertz, Sensorless Vector Control, Economizer SVC motor control, Closed Loop Velocity Vector Control, Surface Mount and Interior Permanent Magnet Motor (without encoder), Interior Permanent Magnet Motor (with encoder). Aside from these standard control techniques, the 25B-E012N104 is also capable of acting as a stand-alone controller as it is capable of Proportional + Integral (PI) control algorithm which is applicable in a wide range of applications, The 25B-E012N104 support local and remote configuration through the embedded standard Human Interface Module (HIM) while remote configuration and operation can be implemented in a variety of ways - with the utilization of the embedded I/O channels by hardwiring external input signals to dictate the drive operation or through the Ethernet I/P communication interface via premiere integration where drive parameters are linked with Logix controller add-on instructions to become part of the actual user program, enabling the drive to be dynamically operated.

The 25B-E012N104 is manufactured by Allen Bradley. This device is a drive that is used to control an AC motor The drive is part of Allen Bradley’s series of PowerFlex 525 Drives. The 25B-E012N104 has an input voltage rating of up to 600 Volts AC. The output current of this drive can be set to support motors rated 12 Amps. The drive also features a three-phase power solution to provide a more effective approach to ensuring the motor attached to the drive can be controlled with a significantly lower risk factor associated as compared to utilizing a drive with a single-phase power supply. An open-type IP20-certified enclosure is installed in the Allen Bradley PowerFlex 525 Drive 25B-E012N104. This provides for a protected device that can be used in a facility where physical hazards may be a problem during day-to-day operations. The device is protected against larger physical interferences. At the same time, it is important for a facility to realize that this device will not offer protection against hazardous environments where liquids and smaller particles are present. The device can be connected through a variety of communication ports included in the drive, including an EtherNet port. This allows configuration files to be uploaded to the drive in order to support the facility’s operations without producing any problems in regards to the automation required to improve the overall production rate of the facility.
