The 20DD3P4A3EYNACGNE is a variable frequency drive from Allen Bradley's PowerFlex 700S range. It functions using vector control (Field Oriented Control - FOC) with feedback, optimizing control for various applications. The user interface is accessible through an LCD screen paired with a numeric keypad, allowing for straightforward programming and monitoring.
This drive is contained within an enclosure rated at IP20 and NEMA 1, suitable for indoor applications. It includes a brake IGBT but does not come with a resistor, maintaining a compact design. The unit can handle overload conditions, providing 110% output for up to one minute and 150% output for a brief three seconds, thereby facilitating temporary peak demands.
Electrically, it operates off a three-phase input voltage of 480 VAC and offers a continuous output current of 3.4 A, while the input current on the DC bus measures 3.0 A. The frequency range spans from 0 to 400 Hz, catering to diverse operational needs. Communication with other devices utilizes ControlNet DPI coaxial connections. The speed accuracy of this drive is impressive at ±0.1% within a 120:1 range, ensuring precise motor control.
Operating efficiency is approximately 97.5% when at rated load, signifying low energy consumption relative to performance. Overall, the 20DD3P4A3EYNACGNE represents a robust solution for applications requiring reliable and efficient variable frequency drive capabilities.
