The Allen-Bradley 25B-D4P0N104 is an alternating current drive that is primarily used in a variety of control systems to control the rotational speed of mechanical components in the industrial system. The device is equipped with an isolated gate bipolar transistor that improves the efficiency and efficacy of the alternating current drive. A standard braking system is also provided to enhance the speed control characteristics of the device. The drive can also be used for torque control applications and possesses the ability to modulate the frequency of the input signals transmitted to the device. The drive functions on an input power supply of 480 volts of three-phase alternating current and is compatible with a voltage supply with a frequency ranging from 47 Hertz to 63 Hertz.

The Allen-Bradley 25B-D4P0N104 is produced by Rockwell Automation and is equipped with fuses and circuit-breakers to protect the components of the industrial automation system from sudden spikes in voltage and current. In order to add an additional layer of protection to the control system, the alternating drive is also designed to incorporate the PowerFlex Safe-Torque-Off function. The primary function of the Safe-Torque-Off mode is to block gate-firing signals from affecting the insulated gate bipolar transistors in the alternating current drive. This ensures that the transistors function as per the user’s requirement and allows the operator to control several aspects of the control system. The Safe-Torque-Off mode can also be used in conjunction with other safety devices and switches to ensure the protection of critical components in the automation system.

Part number 25B-D4P0N104, which is a frequency AC drive, is part of the PowerFlex 525 series product line that was produced by the company known as Allen-Bradley. With an input voltage rating ranging from 323 (three hundred twenty-three) to 528 (five hundred twenty-eight) volts, this AC drive by Allen-Bradley has a power loss of sixty-two (62.0) watts (W) total. The maximum input rating in kVA of this product is five point two (5.2) kVA, and it also has an input rated current of five point seven (5.7) amps, or amperes. With a frame size belonging to category A, this frequency drive has a design that utilizes an enclosure of the open-type variety. On normal duty, this Allen-Bradley product has a 2.0 (two) horsepower (Hp) output and 1.5 kW (kilowatts) of power. When operating at heavy-duty, this Allen-Bradley frequency drive has a 2.0 (two) horsepower output and 1.5 kW (kilowatts) of power, as well. The output current is four point zero (4.0) amps, therefore, approximately making this Allen-Bradley product 85% efficient. This AC drive by Allen-Bradley offers support for accessory cards. This is done without the worry of the device's footprint changing. This device can support up to 2 cards at a time. The 25B-D4P0N104 frequency drive is capable of interacting with other devices, as well as controlling the Ethernet network through its embedded Ethernet port. This Allen-Bradley product also has an RS-485 serial interface embedded within it. This serial interface allows for a multi-drop communication setup. The temperature range recommended for this AC drive to be suitable for operation ranges between -20 to 50 (negative twenty to fifty) degrees Celsius, or -4 to 122 (negative four to one hundred twenty-two) degrees Fahrenheit. The dimensions of this drive measure out to 152 millimeters x 72 millimeters x 172 millimeters. This product weighs 1.1 kilograms, which equals 2.4 pounds.

The 25B-D4P0N104 is a PowerFlex 525 frequency drive. The drive is AC-powered and requires an input voltage rating of 323-528 volts. The drive has a total power loss of 62 watts. During both normal and heavy-duty, the drive has a horsepower rating of 2.0 hp and a power rating of 1.5 kilowatts. During both, the drive maintains an output current of 4 amperes. The drive is rated for an open type of enclosure and has an A frame size. The driver provides protection against bus overvoltage, bus undervoltage, overcurrent, ground faults, and short circuit trips. The 25B-D4P0N104 also comes with the MainsFree programming feature, which lets users quickly configure the 25B-D4P0N104 without having to power up the control module. The 25B-D4P0N104 interacts through an embedded Ethernet/IP port, allowing control of the Ethernet network, as well as a built-in RS-485 serial interface, allowing for a multi-drop communication setup. It is recommended that the drive be operated in a temperature range between -20-50 degrees Celsius, otherwise derating will occur. The drive also has a recommended maximum operating altitude of 1000 meters, or 3300 feet. If the drive is used above this maximum, the maximum ambient temperature must be derated by 5 degrees Celsius (9 degrees Fahrenheit) for every additional 1000 meters. The output current must also be derated by 10% for every additional 1000 meters. The 25B-D4P0N104 AC drive is ATEX, KCC, KUV, CE, RCM, and cUL-us certified. The drive has dimensions of 152 x 72 x 172 millimeters and weighs 1.1 kg or 2.4 pounds.
