The 22C-B145A103 is an adjustable frequency AC drive from the PowerFlex 400 family, which is manufactured by Allen Bradley. These drives are suited for fan and pump applications and offer a wide range of features for system integration. This module from the PowerFlex family has a built-in PID control loop, which is used to maintain a process variable, such as pressure or flow, at the desired set point. The 22C-B145A103 operates on an input voltage of 30-phase 240 Volts AC and has a current rating of 145 Amperes. The power at the rated current is 37kW or 50 HP.  It comes in a panel mount IP30 NEMA Type 1 enclosure with a fixed keypad as an interface module. The 22C-B145A103 drive measures 370 millimeters in width, 605.5 millimeters in height and 259.2 millimeters in depth. This drive supports various communication protocols, such as RS-485, Drive Serial Interface (DSI), Modbus RTU, Metasys N2 and P1-Floor level Network. The interface keypad has an integral 2 line by 16 character display LCD with 5 LED indicators.

The temperature tolerance for the 22C-B145A103 is from -10 to 45 degrees Celsius and the relative humidity should be 0 to 95%, non-condensing. It is recommended that this drive is not installed in an environment that contains volatile or corrosive gas, dust, or vapors, as these may damage the drive’s components. This drive should be stored away from the corrosive atmosphere if it is not being used for longer periods of time. The 22C-B145A103 has a UL certification and is also certified to AS/NZS, 1997 Group1 class A, and CE certified for all applicable European directives, including EMC Directive (89/336) and Low voltage directive (72/23/EEC).
