The catalog number 25C-CTM1 is the catalog number for a spare part that has been designed and manufactured by Allen-Bradley/Rockwell Automation for applications with the adjustable frequency AC drives from the Allen-Bradley PowerFlex 527 series. The product code 25C-CTM1 specifically represents a control module that is made to operate as a part of a high-performance industrial AC drive system. The 25C-CTM1 control module comes as part of a spare parts kit and it includes a front cover for installation. The module is compatible with drives that have frame sizes of A to E. These compatible drives can also operate on voltages ratings of 240 Volts, 480 Volts, and 600 Volts AC. The 25C-CTM1 control module is made for drives with various protective features and drives that can tolerate a force of 15 g of shock and 2 g of vibration while operating. These drives can be mounted on DIN rails or with screws.

The storage temperature range of the Allen-Bradley/Rockwell Automation 25C-CTM1 PowerFlex 527 series control module is from -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit) for frames A to D, and the storage temperature range is from -40 to 70 degrees Celsius (-40 to 158 degrees Fahrenheit) for drives with Size E frames. The ambient temperature range of the surrounding air is -20 to 60 degrees Celsius (-20 to 140 degrees Fahrenheit) for operation. The maximum operating altitude for the 25C-CTM1 control module without derating is 1000 meters (3300 feet) and the maximum operating altitude is 4000 meters (13,200 feet) with derating. The frequency tolerance range is 47 to 63 Hertz and the voltage tolerance range is -15% to +10%. The efficiency rating of the drives compatible with the 25C-CTM1 control module is 97.5% (typical) and the programmable output frequency range is 0 to 590 Hertz.
