Part number 20DC105A3QYNARNNA from Allen-Bradley is classified as an adjustable frequency AC drive. This unit is designed for three-phase applications and operates efficiently at a voltage level of 400 volts AC. It manages a normal-duty current rating of 105 amps, making it suitable for various industrial applications.
This drive is encased in an IP20-rated NEMA Type 1 enclosure, providing protection against dust and other environmental factors. The human-machine interface includes a full numeric LCD, which allows for straightforward monitoring and configuration of the drive settings. However, it does not come with accompanying documentation.
The 20DC105A3QYNARNNA features an IGBT brake, ensuring smooth motor control during operation. Additionally, it incorporates an adjustable bus undervoltage trip feature that can be customized based on operational requirements, improving the safety of the system.
For temperature management, the heat sink thermistor is continuously monitored by a microprocessor, providing overtemperature protection when necessary. When the drive is not in use, it supports a logic control ride-thru time of 0.25 seconds, which helps maintain system integrity. The power ride-thru capability allows it to sustain operation for 15 milliseconds at full load during brief power interruptions.
