20DR125A3ENNACNBN

The 20DR125A3ENNACNBN from Allen-Bradley is classified as an adjustable frequency AC drive geared for advanced industrial applications. This model is engineered to function at a voltage of 650V DC, making it suitable for systems requiring robust performance in heavy-duty environments. The drive supports three-phase operations, accommodating an input current capacity of up to 125 amps, which ensures effective handling of varying load demands.

This drive features an enclosure rated at IP20, adhering to NEMA Type 1 specifications, offering adequate protection for indoor use against dust and other physical contaminants. Designed with user-friendliness in mind, it provides a full numeric LCD display to facilitate straightforward monitoring and control.

In terms of safety features, there is no integrated braking system. However, the drive is equipped with an adjustable bus undervoltage trip, allowing users to customize protections based on operational conditions. Additionally, the unit includes a heat sink thermistor monitored by a microprocessor to trigger an overtemperature trip, ensuring that the system remains within safe operating parameters.

As for operational reliability, the logic control provides a ride-thru capability of 0.25 seconds when the drive is not actively running, helping to maintain control during brief power interruptions. Under full load conditions, the unit ensures power continuity for up to 15 milliseconds, fortifying its performance during transient events. The 20DR125A3ENNACNBN is, therefore, an ideal choice for applications demanding precise control and dependable operation.
