25B-D017N114 Allen Bradley PowerFlex 525 4kW (5Hp) AC Drive

The 25B-D017N114 is a PowerFlex 525 adjustable frequency AC drive from Allen-Bradley. This drive a compact, scalable drive that is used primarily for modulating speed control of an AC motor. Aside from this purpose, Adjustable AC frequency drives simultaneously offers energy saving features and motor protection functionalities as it comes with fully-programmable start-up, operational and shutdown parameters which can be configured according to the control requirements intended for the motor.

The 25B-D017N114 operates when supplied with voltage range of 323-528 VAC and frequency range of 47-63 Hz. It delivers output current of 17 Amperes and 7.5 kW or 10 HP towards the motor. Additionally, the programmable output frequency is 0-500 Hz. This drive maintains the basic motor control features such as Start / Stop; Forward / Reverse / Jog and Local / Remote operation. Speed control can be initiated manually through the installed potentiometer / frequency adjustment dial installed to the Human Interface Module (HIM), by installing an external potentiometer and wiring to the potentiometer input terminal or via an external speed reference which can be 0-10VDC, 0-20 mA or 4-20 mA signal. Additionally, speed control may also be implemented over communication network, via the embedded Ethernet I/P or RS485 communication interface. All these methods can be done manually or remotely, utilizing different control methods supported by this drive, specifically, 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).
