20DR156A0NNNACGNE

The 20DR156A0NNNACGNE from Allen-Bradley belongs to the PowerFlex 700S series and is classified as an adjustable frequency AC drive. It operates at a voltage specification of 650 volts DC, designed to facilitate three-phase applications with an input current capacity of up to 156 amps.

Housed in an IP20-rated enclosure that corresponds to NEMA Type 1 standards, this unit is suitable for indoor installations, ensuring basic protection from dust and contact. The human interface design features a blank cover, indicating that this unit does not come with an integrated control panel or interface.

Documentation for this model is not provided, suggesting that users should already possess familiarity with similar devices or seek external resources for integration and management. The drive does not include a braking system, focusing on core adjustable frequency functionality.

For user safety, the device includes an adjustable bus undervoltage trip feature that allows customization for operational thresholds. The heat sink is supplemented with a thermistor that is monitored by a microprocessor, which activates an overtemperature protection mechanism when necessary.

During operation, the drive can maintain logic control ride-thru for a period of 0.25 seconds when not actively powering a motor. Furthermore, it has the capability to sustain power ride-thru for 15 milliseconds while at full load, ensuring operational continuity during brief power fluctuations.
