The Allen Bradley 20BD156A3NNNAND0 is a highly capable adjustable-frequency AC drive equipped to efficiently manage motor operations. It can support a maximum output frequency of 420 Hz while providing an output current rating of 156 A. The drive operates at an input voltage of 480 V AC specifically designed for 3-phase connections.

This model is built without a brake resistor and incorporates an IGBT module for enhanced braking capability. User interaction is simplified through an integrated LCD screen coupled with a numeric keypad, facilitating direct monitoring and control. The control method employed is a vector type, operating with 120 V I/O, ensuring precise motor control.

With a power draw of 122 kVA, the drive supports significant operational loads, accommodating both 125 HP and 100 HP motor power ratings. The frequency precision of the output is maintained within ±0.01%, reflecting the drive's reliability for sensitive applications.

Moreover, the digital I/O latency during startup ranges from 9.2 to 16 ms, while the stopping phase achieves 9.2 ms. The logic ride-through feature allows for continuity during transient events, configurable from 0.5 to 2 seconds. This drive is also capable of supporting adjustable acceleration and deceleration ramp settings of up to 3600 seconds, with two distinct ramp profiles available. The carrier frequency settings can be configured at 2, 4, 8, or 10 kHz to suit specific operational needs, making the 20BD156A3NNNAND0 adaptable for various industrial requirements.
