20DD300A3ENNBNASE

The 20DD300A3ENNBNASE from Allen-Bradley is an adjustable frequency AC drive designed to meet the sophisticated needs of industrial applications. Operating at 480 volts AC, this drive is configured for three-phase systems and can handle an input current of up to 300 amps. It is housed within an enclosure rated IP20, compliant with NEMA Type 1 standards, facilitating adequate protection against dust and other contaminants in standard indoor environments.

Interaction with the drive is made efficient through a full numeric LCD, which presents vital operational data and settings in an accessible format. A quick start guide is included to assist with installation and configuration processes, promoting ease of use.

Notably, this model does not feature a braking system but incorporates an adjustable bus undervoltage trip to provide protection against voltage drops. Thermal safety is ensured via a heat sink thermistor, which is monitored by a microprocessor that can trigger an overtemperature trip if exceeding defined limits.

When it comes to stability, the drive is equipped with a logic control ride-thru capability lasting 0.25 seconds when the drive is not in operation. This allows it to maintain critical system functions during brief power interruptions. For peak operational resilience, it offers a power ride-thru duration of 15 milliseconds while under full load, ensuring reliable performance under demanding conditions.
