Features:

  • Interface Between the PowerFlex 750 Drive System and Motor Power Stage
  • Provides Capability of AC Power Signal Conversion with High-Power Drive Support
  • Operates in Conjunction with the PowerFlex 750 Series Variable Frequency Drives
The Allen Bradley 333299-A01 serves as the Inverter Power Drive Board within the PowerFlex 750 drive architecture, delivering reliable power conversion and signal distribution to all drive modules within the system. It continuously processes incoming AC power (480 VAC, three-phase) and converts this power through the drive backplane to support steady state operation of the inverter section and associated control modules. Consistent power transfer is standard with the 333299-A01, ensuring stable motor control under varying load conditions. The 333299-A01 incorporates industrial-grade circuitry designed for high-anti-interference performance within the PowerFlex 750 rack.

The 333299-A01 provides essential power interface functions common to the entire drive system, and is a critical component of the motor control path, directly affecting the proper, normal operation of the overall variable frequency drive system. One 333299-A01 power drive board is required per Frame 7 chassis depending on the power rating requirement up to 300 HP. The 333299-A01 occupies a dedicated position within the drive assembly and is always integrated as part of the core power stage infrastructure.

For high-power motor applications, the PowerFlex 750 system requires the 333299-A01 power drive board installed in the designated slot. In addition to standard power conversion operation, the 333299-A01 also performs precise signal conditioning. The 333299-A01 configuration executes power distribution using the internal circuitry specified in the drive options. Using this method, the power drive system continually monitors the health of power signals. If the system detects that power parameters are outside configured voltage or tolerance levels, it will automatically regulate output and maintain system stability through the integrated control mechanisms.

The 333299-A01 Allen Bradley Power Drive Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
