The Allen-Bradley 22A-B8P0N104 PowerFlex 4 variable frequency drive is manufactured by Rockwell Automation. It offers output current of 8 Amperes and an output power rating of 1.5 kilowatts, equating to 2 Horsepower. It also offers a programmable output frequency of the full range from 0 Hertz to 240 Hertz. The Allen-Bradley 22A-B8P0N104 PowerFlex 4 variable frequency drive allows the operator to exercise complete control of speed. It also provides users with an accessible interface via its the human-machine interface module (HMI), a liquid crystal display (LCD), and a built-in fixed-position keypad. The output voltage range of the Allen-Bradley 22A-B8P0N104 PowerFlex 4 variable frequency drive runs from 200 Volts to 240 Volts AC. Its input current is 9.5 Amperes, and it is rated 4.5 kilovolt-amps of apparent power. The Allen-Bradley 22A-B8P0N104 PowerFlex 4 variable frequency drive makes use of circuit protection provided by an Allen-Bradley 140M-C2E-C16 motor and an Allen-Bradley 100-C12 contactor.

This drive uses an IP20 type of open enclosure, and it is rated for 60 Watts of power dissipation along the wire. The operational efficiency falls slightly below some of the more sophisticated units from Allen-Bradley at a peak of 97.5%. The Allen-Bradley 22A-B8P0N104 PowerFlex 4 variable frequency drive offers integral motor overload protection of 150% for 1 minute and up to 200% overload for no more than 3 seconds. It also has a 200% hardware limit for no more than 1 minute, and instantaneous fault protection of up to 300% for a maximum of 3 seconds.

The installation of the Allen-Bradley 22A-B8P0N104 is fast and simple due to the DIN rail mounting system. For added flexibility, panel mounting is also available. A built-in keypad allows for immediate use through the control and potentiometer keys. To further ensure quick and easy use, the ten most typically used application parameters are programmed in the Basic Program Group. As with the other PowerFlex drives, the keys for programming have the same function, so the same methodology can be used to program all PowerFlex drives. An easily understandable display of drive information and status is available due to a four-digit display with ten LED indicators. Connection with a personal computer can be achieved through the RS-485 or connection with a DF1 port on a controller can be achieved with a serial converter module. A trademark function for control and programming flexibility called the Copycat function, is integrated into the NEMA/UL Type 4X remote and NEMA/UL Type 1 liquid crystal display keypad. Designed to minimize panel space, the PowerFlex has zero-stacking so that multiple drives can be mounted adjacent to each other with no space between drives. For adjacent stacking, ambient temperatures up to 40 °C are allowable, saving valuable panel space. If there is minimal space between the drives, up to 50 °C temperatures are allowed. The PowerFlex 4 Drive automatically provides auto boost (IR compensation) and slip compensation. The Allen-Bradley 22A-B8P0N104 provides superior regulation of speed, consistently maintained levels of high torque across the entire range of speed, and good regulation of speed with increased loads.
