The Allen-Bradley 74101-482-54 drive’s alternative part number is 1336-BDB-SP23D and it operates on a voltage of 575V AC. It is also a member of the Allen-Bradley PCB Gate Drive Board series that puts out 50 HP of power. This board is engineered for adjustable frequency AC drives and each of its modules fits well with the Frame Sizes A, B, C, D, or E. The series in which the 74101-482-54 board belongs can function as spare board parts for 1336 PLUS, REGEN, IMPACT, FORCE, and PLUS II adjustable frequency AC drives. The boards in these series can also operate effectively with drives rated between 3 and 800 horsepower. The operating voltage of the adjustable frequency drive powers this drive board.

The brake chopper module of the 74101-482-54 should be installed properly by the users for maximum performance, making it reliable. The brake chopper module should be installed vertically. The brake chopper modules are installed inside the enclosure. A minimum clearance of 152.4 mm must be allowed between the brake chopper modules during installation so that they can perform effectively. If the brake chopper requires more than one module, then they should be mounted within 10 ft. of the chopper module. All the resistor banks of the 74101-482-54 drive board should have a certain distance between them because they are all application dependent. Each module on this board also features a thermostat which effectively provides protection to the drive board against component damage and overheating. The user has to set Parameter 11 of this board to the disabled state when the installation of a dynamic braking is underway. The brake module ratings of this drive board have a fault contact which is effective in providing a remote output signal.
