20BD156A3AYNANC0

The Allen Bradley 20BD156A3AYNANC0 is part of the PowerFlex 700 series and is classified as an adjustable-frequency AC drive. This unit accepts an input voltage of 480 V AC from a three-phase source and is capable of providing a motor output voltage of 460 V AC, making it compatible with a variety of electric motors. The continuous output current for this drive reaches 156 A, allowing significant loads to be managed effectively. This model has a rated horsepower of 125 HP, indicating its capability for robust application in industrial contexts.

In terms of efficiency, the drive operates at an impressive rate of 97.5%, resulting in an approximate power loss of 1.85 kW during operations. Its overcurrent and overload protection systems can handle a maximum of 300% of normal operating conditions, with the ability to sustain 150% for up to 3 seconds, ensuring resilience during demanding operational phases.

The maximum frequency this drive can achieve is 420 Hz, while it employs either a sensorless vector or V-Hz control strategy to maintain performance across various applications. The enclosure is rated at IP20 / NEMA 1, suitable for installation in non-hazardous indoor environments, providing basic protection against dust and contact. Inputs and outputs are plentiful with 6 digital inputs, 3 digital outputs, 2 analog inputs, and 2 analog outputs, enabling flexible configuration and integration.

The unit incorporates advanced ride-thru capabilities that allow logic to last between 0.5 to 2 seconds, while power can withstand up to 15 milliseconds during brief interruptions. For controlling motor operations, it implements a pulse-width modulation (PWM) strategy with frequencies ranging from 2 to 10 kHz, ensuring smooth and precise operation throughout its duty cycle.
