20DD034A5EYNARCBL

The 20DD034A5EYNARCBL adjustable frequency AC drive from Allen-Bradley operates with a voltage rating of 480 volts AC, designed specifically for three-phase applications. It can manage an input current of 34 amps, suitable for various demanding tasks in industrial settings. This unit is housed in an enclosure that meets the IP20 and NEMA Type 1 specifications, providing adequate protection for routine use.

An integrated programming-only LCD serves as the human-machine interface, allowing users to navigate settings easily, although there is no detailed documentation included apart from the Quick Start Guide. The drive is equipped with an IGBT braking system, ensuring efficient control for connected motors.

Safety features are highlighted by the adjustable bus undervoltage trip, allowing tailoring based on operational needs. For thermal regulation, a heat sink thermistor is continuously monitored by a microprocessor, which activates an overtemperature trip if surpassing safe limits. This unit is designed with reliability in mind, as indicated by its logic control ride-thru feature, supporting a duration of 0.25 seconds when the drive is not currently operational. Moreover, it offers a power ride-thru function for a span of 15 milliseconds at full load, maintaining operation during brief disruptions. Overall, the 20DD034A5EYNARCBL is a capable AC drive for precise control within industrial applications.
