20DD385ACENNBDANE

The 20DD385ACENNBDANE model from Allen-Bradley is an adjustable-frequency AC drive explicitly designed for demanding industrial applications. Operating at 480 volts AC, it handles three-phase configurations with a robust normal-duty current capacity of 385 amps. This drive ensures reliability across various motors and setups.

Its construction meets NEMA Type 1 standards and is rated IP20, which protects against dust and other contaminants in non-harsh environments. A significant feature of this module is its full numeric LCD, which is mounted on a door. This allows users to easily monitor and manage the unit's settings.

Safety features include an adjustable bus undervoltage trip mechanism, enabling customization according to specific application needs. While this model does not feature a traditional braking system, it compensates with a heat sink thermistor that is actively monitored by an onboard microprocessor. This setup triggers an overtemperature trip if conditions exceed safe operating limits. For enhanced operational stability, a logic control ride-thru function is available for 0.25 seconds when the drive is not in operation. Additionally, it maintains power ride-thru for up to 15 milliseconds under full load, ensuring consistent performance during transient conditions. Overall, the 20DD385ACENNBDANE is engineered to provide reliable motor control across a variety of demanding industrial tasks.
