The 20DD077A3EYNANDNL, classified as an adjustable frequency AC drive, is built by Allen-Bradley under the Rockwell Automation umbrella. This drive is designed to function at 480V AC within a three-phase voltage setup and can support a normal-duty current of up to 77 amps.
Constructed with a NEMA Type 1, IP20-rated enclosure, this unit offers basic protection suitable for indoor applications. For user interaction, the drive integrates a full numeric LCD display, which assists in monitoring and configuration.
In terms of safety features, it utilizes an IGBT braking system, ensuring effective control during operation. The adjustable bus undervoltage trip allows for flexibility, accommodating different operational requirements. Additionally, the heat sink thermistor is supervised by a microprocessor, providing essential protection against overheating by triggering an over-temp trip when necessary.
The drive also incorporates a logic control ride-thru capability of 0.25 seconds while not in operation, maintaining stability during brief power outages. Furthermore, it offers a power ride-thru duration of 15 milliseconds under full load conditions, ensuring reliable operation despite transient power fluctuations. The 20DD077A3EYNANDNL delivers robust performance across a range of demanding applications.
