Allen Bradley 20BH875N0NNNNNC0 DC Input AC Drive / Variable Frequency Drive

FAQ

Q1: What is the 20BH875N0NNNNNC0?
It is an Allen-Bradley PowerFlex 700 high-power drive designed for large industrial motor-control applications using a 540 VDC input.

Q2: What is the input voltage?
The drive uses a 540 VDC input and is specifically configured without a precharge circuit.

Q3: What are the current and power ratings?
It is rated at 875 A continuous output, with a 500 kW normal-duty rating and 400 kW heavy-duty rating. The short-term output ratings are 963 A for one minute and 1313 A for three seconds.

Q4: What frame size is this model?
The 20BH875N0NNNNNC0 uses the very large Frame 10 PowerFlex 700 chassis.

Q5: Does it include a HIM keypad or display?
No. The N0 configuration is supplied with an HIM blank plate rather than a local keypad/display.

Q6: Does it have a built-in braking resistor?
No. This configuration has no brake IGBT and no drive-mounted brake resistor.

Q7: Does the drive include a communication module?
No. The 20BH875N0NNNNNC0 is specified without an internal communication module and uses 24 VDC control I/O.

Q8: What should be considered when installing this drive?
Because it is an IP00/open-type, 875 A, Frame 10 drive, cabinet protection, DC-bus design, ventilation, grounding, protection devices, and mechanical handling need to be considered carefully before installation. Rockwell’s technical documentation specifies a 2 kHz PWM frequency and 40 °C operating-temperature basis for the rating data.
