The Allen-Bradley 20DB028A3EYNA6CNL is an adjustable frequency AC drive that operates efficiently under 240V AC in a three-phase configuration. It is capable of supporting an output of 32.2 amps at 208V, catering to a variety of industrial applications. The drive's enclosure is rated IP20, aligning with NEMA Type 1 standards, which ensures adequate protection in standard working environments.
Users will benefit from the full numeric LCD human interface terminal, providing clear visibility and ease of use during operation and programming. Documentation is included in the form of a quick start guide, facilitating straightforward initial setup.
Key features of this model include an IGBT brake, which enhances operational efficiency, and an adjustable bus undervoltage trip to safeguard against voltage drops. The heat sink thermistor is closely monitored by the microprocessor to detect over-temperature conditions and act accordingly.
The drive allows for logic control ride-thru capability of 0.25 seconds while the drive is not in operation, ensuring minimal disruption during brief power outages. For critical load situations, power ride-thru is maintained for 15 milliseconds at full load, which helps in sustaining performance across varying operating conditions.
