The 20DD040A3EYNADACE is an adjustable-frequency AC drive within Allen-Bradley's PowerFlex 700S range. This unit is engineered to function efficiently at 480V AC in three-phase systems and supports a continuous normal-duty current of 40 Amps. Its robust construction, including an IP20-rated enclosure that meets NEMA Type 1 standards, makes it intended for indoor use where protection from incidental contact and dust is required.
For user interaction, the drive includes a full numeric LCD, providing clear information visibility for operators. The braking system uses IGBT technology, which allows for efficient motor control under varying operational demands.
An adjustable bus undervoltage trip feature helps prevent malfunction due to voltage drops, and the heat sink thermistor is supervised by an integrated microprocessor. This ensures that overheating is detected and managed effectively, activating an overtemperature trip if threshold conditions are met.
For operational continuity, the device can maintain logic control ride-thru for up to 0.25 seconds when not actively running. Furthermore, it can hold power for 15 milliseconds at full load during brief interruptions, enhancing its reliability in demanding environments.
