The Allen-Bradley 25B-B8P0N104 is a PowerFlex 525 adjustable Frequency AC drive. This drive is capable of implementing basic and advanced motor control via its modern features and specifications. This drive supports a variety of control methods such as Volts / Hertz, Sensorless Vector Control (SVC), Closed loop velocity vector control and Permanent Magnet motor control method. Which enable it to implement both Speed and Torque control. In addition, this drive is also capable of PointStop which stops motor load in a consistent position without encoder feedback, Closed loop feedback with an optional encoder card and Point-to-point positioning mode. For automatic control of analog loops, the 25B-B8P0N104 may act as a Proportional + Integral + Derivative (PID) controller and supports up to Two (2) analog control loops.

The 25B-B8P0N104 has an input supply rating of 200-240VAC, 3-phase while output ratings include 0-230VAC, 3-Phase, rated Current of 8.0 A and Power of 1.5 kW (2.0 HP) both for normal and heavy-duty operation. This drive has a fully programmable frequency output of 0-500 Hz.

This drive is equipped with increased number of I/O terminals. I/O terminals include Seven (7) Inputs; Two (2) Opto Outputs and Two (2) Relay Outputs; Two (2) Analog Inputs that support 4-20 mA signal; One (1) Analog output that delivers 0-10VDC and 4-20 mA signals. A dedicated potentiometer input terminal is also provided that may be used to regulate the drive’s output frequency locally. Compatible potentiometer is 1-10KOhms, 2W, minimum.

This drive has an acceptable input range of -15% to +10% of the drive rating at 47 to 63 Hertz, and it has a total power rating of 1.5 Kilowatts. It has a programmable current limiting capability, programmed for 200% on the hardware limit, and 300% of the total output rating on the instantaneous fault. It has an overload capacity of 110% of the rated output for 60 seconds, and it is capable of providing Class 10 Electronic motor overload protection that meets the NEC article 430 standard. The 25B-B8P0N104 does not come standard with a line filtering capability but it has a removable metal oxide varistor, which provides trouble-free operation in ungrounded electrical settings. It has a robust ride-through time (100 milliseconds), which allows for continuous output even in low voltage conditions, and it is designed with Bus AC voltage regulation with standard trip ratings of 290 Volts AC (overvoltage) and 150 Volts AC (under voltage). It is programmed for enhanced performance via the standard volt per hertz control, sensorless vector control, or the closed loop vector control. It has a performance range of ±0.5% of the base speed across a 100: 1-speed range, and it offers an operational efficiency of 97.5%. It features an adjustable pulse modulated frequency for reliable speed control, and it provides a 3-phase voltage output, which is a function of it programmable output frequency (0 to 500 Hertz). The 25B-B8P0N104 supports the MainsFree protocol which allows for easy configuration by a PC using USB a cable, and it also supports DSI communication, which allows the drive to be connected in a multi-drop configuration. The 25B-B8P0N104 has an ambient operating temperature of -20 to 50 degrees Celsius (-4 to 122 degrees Fahrenheit), with a storage range of -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit), and it has an IEC level 3C2 conformal coating designed to prevent wears and tears from chemicals and gases. The 25B-B8P0N104 has an approximate weight of 1.1 Kilograms, with 72 x 152 x 172 millimeters shipping dimension, and it is CE, c-UL-us, RCM, RoHS, and KCC certified.

The 25B-B8P0N104 comes with integrated safety functionality as this drive supports Safe-Torque Off (STO) functionality. Dedicated STO terminals are embedded along the drive’s input terminals.
