25B-D024N104 Allen Bradley PowerFlex 525 AC Drive

Allen-Bradley 25B-D024N104 is a PowerFlex adjustable Frequency AC Drive. This drive, among any other adjustable frequency drives are primarily used to implement discrete motor control such as Start / Stop, Forward / Reverse, Jog / Manual and Automatic and Single / Continuous operation. Aside from carrying standard motor control commands, this adjustable frequency AC drive enables analog speed control through by providing PWM signal to the motor, implemented through a variety configurable control methods such as Volts per Hertz (V/Hz), Sensorless Vector Control (SVC), Closed loop velocity vector control and Permanent Magnet motor control.

Aside from the control methods supported by the 25B-D024N104 include positioning control through Closed loop feedback with an optional encoder card and Point-to-point positioning mode. It also implements PointStop technology which is a trademark of Allen-Bradley, used to halt motor load in a consistent manner without requiring use of an encoder feedback. This adjustable frequency drive also comes with integral Proportional + Integral + Derivative (PID) control algorithm capability which allow the drive to automatically regulate and maintain the speed of the motor at a specified setpoint without the need of an external controller that implements the same control algorithm.

Commonly called as a Variable Frequency Drive (VFD), Variable Speed Drive (VSD), Adjustable Speed Drive (ASD) or simply a frequency inverter, this unit operates when supplied with nominal voltage of 480VAC, 3-Phase. It delivers output power of 7.5 kW or 10.0 HP for both normal and heavy-duty operation. The drive’s output Current is 24.0 Amperes with an IP20 NEMA / Open rated enclosure.

The 25B-D024N104 features an innovative modular design and it is, therefore, one of the fastest and easiest PowerFlex 525 drives to install. The 25B-D024N104 is a cost-effective drive because it comes with the economizer motor control features that allow the motor to save energy. The 25B-D024N104 comes with an embedded EtherNet/IP port with integral an RS-485 port with Modbus RTU/DSI for communication. Another human-machine integration interface is the LCD screen which allows for text scrolling. The LCD screen comes with support for multiple languages and allows programming through the provided USB cable. The 25B-D024N104 also features embedded input/output ports with 7 digital inputs and 2 digital outputs. There are 2 analog inputs with 1 analog output and 2 relay outputs. The 25B-D024N104 comes with an internal brake IGBT for the brake resistors. The 25B-D024N104 comes with various certifications that include the ACS 156, ATEX, C-Tick, c-UL, UL and CE, among several other certifications.
