Allen Bradley 20BD125A0ANNANC0 PowerFlex 700 AC Drive 20B

The 20BD125A0ANNANC0 is a PowerFlex 700 AC drive that has an outstanding performance. Manufactured by Allen-Bradley, the 20BD125A0ANNANC0 is one of the AC drives that is meant to be used for controlling a three-phase induction motor in applications that require simple speed control to those that require demanding torque control. The 20BD125A0ANNANC0 is fitted with volts per hertz control, vector control, and it also includes sensorless vector control. The 20BD125A0ANNANC0 Voltage is 480 Volts AC and 3-phase power, 125 Amps current, 100 Horsepower output in normal duty operation and 75 Horsepower of heavy-duty operation. The enclosure type used on the 20BD125A0ANNANC0 is the IP20, NEMA/UL Type 1 enclosure and the 20BD125A0ANNANC0 does not come with a mounted brake resistor. The frequency tolerance for the 20BD125A0ANNANC0 is 47 to 63 Hertz while the displacement power factor is 0.98 across the entire speed range. The maximum short circuit rating is 200,000 Amps Symmetrical with three-phase inputs providing a full rating for the 20BD125A0ANNANC0 drive. For single-phase operation, a rated current of 50% is provided. The output voltage range is 0 to the rated motor voltage while the output frequency range is 0 to 420 Hertz. The 20BD125A0ANNANC0 drive is also designed such that it meets the following standards: The NFPA 70 US National Electrical Code, the NEMA ICS 3.1 Safety standards selection guide and construction code, the IEC 146 International Electrical Code, and the CMAA Specifications. The operating temperature range is 0 to 50 degrees Celsius while the storage temperature is -40 to 70 degrees Celsius. Note that the 20BD125A0ANNANC0 should not be installed in an area where there is an ambient atmosphere with volatile or corrosive gas. In addition, the relative humidity is 5 to 95%, non-condensing. The 20BD125A0ANNANC0 supports multiple programmable stop modes that include the ramp stop, the coasting stop, the DC-brake stop, the ramp to hold stop, and the S-curve stop.

The 20BD125A0ANNANC0 by Allen-Bradley is a Variable Frequency drive which is primarily used to regulate the speed or torque of an AC motor in a wide variety of industrial applications and industries. The 20BD125A0ANNANC0 delivers an output voltage of 0-460 Volts AC, 3-Phase, and an output current of 125 Amperes along an output power of 100 Horsepower at Normal Duty operation and 75 Horsepower at heavy-duty operation. This drive implements speed and torque regulation via the selectable control methods supported by this drive such as Volts/Hertz (V/Hz) and Sensorless Vector Control (SVC).

Aside from the standard selectable control methods, the 20BD125A0ANNANC0 is provided with Allen-Bradley’s trademark technology - specifically, Vector Control with FORCE technology. This control method allows excellent torque control even in low to zero speed zones of the motor. Another patented technology included to this drive is the TorqProve technology which is used to assure control of the load when transferring control between the drive and mechanical brake.

This drive also features open loop and closed loop speed regulation - similarly, open loop and closed torque regulation. The latter provides +/- 5% torque regulation and without an encoder feedback and +/-2% regulation with encoder feedback.

The 20BD125A0ANNANC0 also supports Integral Proportional + Integral (P+I) control, allowing the drive to function as a stand-alone controller, eliminating the need of external PID controllers to implement automatic control of the loop. This also comes with integral IGBT brake, Fast-acting Current limit and Bus voltage regulation, Flying start, Inertia ride-through, Position indexer, and speed profiler.
