20DD300A3EYNBNDNL

The Allen-Bradley 20DD300A3EYNBNDNL is a robust adjustable frequency AC drive suitable for industrial applications requiring reliable performance. This unit operates at a nominal voltage of 480V AC and is configured for three-phase systems. With an input current capacity of 300 amps, it ensures adequate power management.

Constructed in an IP20-rated enclosure that meets NEMA Type 1 standards, this drive is designed for indoor environments where basic protection is sufficient. For user interaction, it features a full numeric LCD, allowing operators to easily read and adjust settings as needed. Comprehensive documentation includes a quick start guide for straightforward installation.

The 20DD300A3EYNBNDNL employs IGBT technology for braking, enhancing control during operation. Users can customize settings with an adjustable bus undervoltage trip to safeguard against low voltage situations. Thermal protection is achieved through a heat sink thermistor, which is monitored by a microprocessor that triggers an overtemperature trip when necessary.

This drive also includes logic control ride-thru capabilities lasting 0.25 seconds during periods of inactivity, ensuring stability during brief power interruptions. It supports power ride-thru for up to 15 milliseconds at full load, maintaining functionality when facing transient power fluctuations. Overall, the 20DD300A3EYNBNDNL ensures effective and reliable motor control for demanding applications.
