The unit 20DD180A3NNNACNNN, manufactured by Allen-Bradley, is classified as an adjustable frequency AC drive. Operating at a substantial voltage of 480V AC and configured for three-phase connections, it can accommodate normal-duty currents measuring up to 180 amps.
This device is constructed within an IP20-rated enclosure compliant with NEMA Type 1 specifications, which provides basic environmental protection. Users can interact with the system via a full numeric LCD display. Furthermore, the 20DD180A3NNNACNNN does not feature a built-in braking system.
Safety features include an adjustable bus undervoltage trip that enhances operational stability. Additionally, the drive incorporates a heat sink thermistor monitored by a microprocessor, which is responsible for overseeing temperature levels and activating a trip if overheating occurs.
For resilience, the drive permits up to 0.25 seconds of logic control ride-thru when not in operation, ensuring settings are maintained during brief power interruptions. Moreover, it can sustain a power ride-thru for up to 15 milliseconds at full load, allowing for continued operation even amidst short variations in power supply.
