20DR248A0ENNANANE

The 20DR248A0ENNANANE adjustable frequency AC drive is a product of Allen-Bradley, part of the PowerFlex 700S series. This unit is rated for a maximum DC voltage of 650V and accommodates three-phase configurations. It provides a maximum input current of 248 amps, making it suitable for high-demand applications.

Constructed with an enclosure rated at IP20 and compliant with NEMA Type 1 standards, it meets basic protection requirements for certain environments. The design features a blank cover for the human-machine interface, indicating a straightforward setup without external controls. A quick start guide is available to assist with installation and commissioning, though detailed documentation is not provided.

This drive does not incorporate a braking system but includes an adjustable bus undervoltage trip feature, allowing users to set operational limits. A heat sink thermistor is continuously monitored by a microprocessor, which can trigger an overtemperature trip if required, ensuring safe operation.

The logic control offers a ride-thru capability lasting 0.25 seconds when the drive is not actively running, maintaining stability during brief interruptions. Additionally, the power ride-thru ensures continued operation for up to 15 milliseconds at full load, providing reliability for critical processes. The combination of these features supports efficient motor control in a range of industrial applications.
