Allen-Bradley's manufactured 25A-D4P0N104 variable frequency AC drive is a PowerFlex 523. This Drive is proficient in speed and torque regulation using a number of control techniques, including volts/hertz (V/Hz) and Sensorless Vector Control (SVC) economizer mode. The 25A-D4P0N104 has a Frame A that may be mounted directly to the panel through the included mounting tabs or via a conventional DIN rail. It should be fitted in an enclosure with an IP20 / NEMA UL Type Open protection classification. It is critical to consider the vibration and shock resilience of a DIN rail while installing. Install this Drive directly to the enclosure to get slightly greater resistance than with DIN rail installation.
In general, a variable frequency AC drive is referred to as a Variable Frequency Drive (VFD), a Variable Speed Drive (VSD), an Adjustable Speed Drive (ASD), a frequency inverter, or just a drive. All of these phrases relate to a device capable of performing main speed control, torque control, and energy conservation, such as the 25A-D4P0N104. To save energy, the 25A-D4P0N104 may be set to avoid excessive inrush current production during start-up and shutdown by offering acceleration, deceleration, ramp-up, and ramp-down characteristics. Additionally, it may be utilized to reduce On/Off cycles by enabling the Drive to work effectively at low speeds, avoiding the Drive of cycling the motor on and off, hence eliminating motor hunting.
The 25A-D4P0N104 AC drive is rated at 1.5 kW or 2.0 Hp and has an input power range of 380-480VAC, 47-63 Hz. The Drive has a modest footprint and is ideal for a broad range of motor control applications. It is modular in design, with a revolutionary and changeable control core that allows for simultaneous program installation and setup. It can work at temperatures as high as 70 °C without derating and comes with a scheme consists fan kit. It is installed side by side, with a 50 millimeter (1.9 inch) essential airflow space at the bottom and top of the Drive. This module is essential for allowing low-cost networking through an integrated RS485/DSI interface. It is designed to be installed in an IP20 NEMA / Open Type chassis and has a frame size of A class. It also comes with a standard interface card and an EMC filtration option.

The Allen-Bradley 25A-D4P0N104 is a PowerFlex 523 adjustable frequency AC drive. This drive is used for implementing Speed control as well as Torque control through a variety of supported control methods such as Volts / Hertz (V/Hz), Sensorless Vector Control (SVC), and Sensorless Vector Control (SVC) economizer mode.
The 25A-D4P0N104 is a Frame A drive that supports both direct panel mounting through the provided mounting tabs or using a standard DIN rail. It requires installation to an enclosure with protection rating of IP20 / NEMA UL Type Open. When installed using a DIN rail, it is important to consider that it offers lesser vibration and shock resistance. To afford slightly higher resistance than DIN rail installation, install this drive directly to the enclosure.
Generally, an adjustable frequency AC drive is more commonly termed as Variable Frequency Drive (VFD), Variable Speed Drive (VSD), Adjustable Speed Drive (ASD), Frequency inverter, inverter or simply a drive. All these terms refer to a device that is capable of primary implementing speed control, Torque control and contribute to energy savings such as the 25A-D4P0N104.
For energy savings, the 25A-D4P0N104 may be programmed to prevent generation of large amount of inrush current by providing start-up and shut-down patterns such as acceleration, deceleration, ramp-up and ramp-down characteristics. It may also be used to lessen On/Off cycles by allowing the drive to operates efficiently with minimum speed, preventing the drive from cycling the motor On and Off thus, preventing motor hunting.
