The 20DJ156A3ENNA1CNK is an adjustable frequency AC drive from Allen-Bradley, part of the Rockwell Automation line. Functioning at a voltage of 600V AC, it supports three-phase circuitry. The unit also permits an input amperage of up to 156 amps. Designed to comply with NEMA Type 1 standards, the drive is housed within a protective IP20 enclosure which safeguards the internal components against contaminants.
User interaction is facilitated through a full numeric LCD, which aids in easy configuration and monitoring. Accompanying the drive is a quick start guide, ensuring proper installation and setup. The model does not include a braking feature, but it incorporates an adjustable bus undervoltage trip, enhancing safety during operation.
For temperature management, a thermistor is present on the heat sink. It is monitored by a microprocessor that can trigger an overtemperature trip if necessary. Logic control functionality allows for a brief ride-thru period of 0.25 seconds when the drive is not in use. Additionally, during full load situations, it can sustain power for 15 milliseconds, providing stability during minor power fluctuations.
