20DD300A3EYNB6CSK

The 20DD300A3EYNB6CSK is a robust adjustable frequency AC drive from Allen-Bradley’s PowerFlex 700S lineup. It operates at a rated voltage of 480V AC in three-phase applications, providing significant capacity with a maximum input rating of 300 amps. This design makes it ideal for a variety of demanding industrial uses.

The AC drive is housed in an IP20 enclosure conforming to NEMA Type 1 specifications, ensuring protection of internal components in normal indoor environments. It is equipped with a full numeric LCD, facilitating easy monitoring and control of settings for the user. A quick start guide is also included to aid in installation and operation.

For safe operation, the drive features an adjustable bus undervoltage trip function, which responds to varying conditions. The braking mechanism employs IGBT technology, ensuring effective stopping power during operation. Additionally, thermal protection is enhanced through a microprocessor-monitored heat sink thermistor that activates an overtemperature trip to prevent overheating.

Users benefit from a logic control ride-thru time of 0.25 seconds when the drive is inactive, which helps maintain system stability. Moreover, it can sustain power ride-thru for 15 milliseconds at full load, supporting resilience against brief power interruptions. This makes the 20DD300A3EYNB6CSK a reliable choice for applications requiring precise motor control and efficient energy management.
