20DD248A3EYNA1CEK

The 20DD248A3EYNA1CEK is an adjustable-frequency AC drive belonging to Allen-Bradley’s PowerFlex 700S series, built by Rockwell Automation. This model is engineered to work effectively at 480V AC and is set up to handle three-phase power systems. With a normal-duty current capacity of 248 amps, this drive is capable of managing significant loads and works well in various industrial applications.

Its enclosure is rated as IP20 and meets NEMA Type 1 standards, offering basic protection against dust and other particulates. Drive integration and interactions are facilitated through a full numeric LCD human-machine interface, making it accessible to operators for monitoring and adjustments.

Incorporating an IGBT braking system ensures that the drive performs reliably, contributing to effective control during operation. An adjustable bus undervoltage trip adds a critical safety feature, allowing customization to meet certain operational thresholds. For thermal management, the heat sink thermistor is monitored by a microprocessor that responds to overheating conditions by triggering an overtemperature trip when necessary.

The drive has embedded logic control ride-thru capability lasting 0.25 seconds when not in operation, which allows the drive to maintain settings during brief outages. Additionally, it supports a power ride-thru functionality that lasts for 15 milliseconds at full load, ensuring reliable operation in the event of short power losses. Overall, the 20DD248A3EYNA1CEK model is structured to provide efficiency and strength in diverse applications.
