20DD125A0EYNANCEL

The 20DD125A0EYNANCEL AC drive from Allen-Bradley is designed for adjustable frequency applications. Functioning at an input voltage of 480V AC, this model is intended specifically for three-phase configurations. It can handle an input current of up to 125 amps, making it suitable for handling significant motor control operations.

This drive is housed in an enclosure rated IP20, consistent with NEMA Type 1 standards, offers basic protection suitable for indoor applications. The human interface is equipped with a blank cover, indicating that it does not have an integrated operational display.

The 20DD125A0EYNANCEL utilizes IGBT technology for its braking mechanism, which allows for precise control of motor speed and torque. An adjustable bus undervoltage trip feature is built into the unit to enhance its protective capabilities. Safety is further ensured through a monitored heat sink thermistor, which triggers an overtemp shutdown via a microprocessor if temperatures exceed operational limits.

For operational stability during interruptions, the device provides a logic control ride-thru capability lasting up to 0.25 seconds while the drive is inactive. Furthermore, it supports a power ride-thru of approximately 15 milliseconds during full load conditions. A quick start guide is included to facilitate setup and integration into existing systems.
