The Allen Bradley 20DD027A3EYNACBSE is an AC variable frequency drive characterized by robust capabilities for motor control. Ideal for industrial environments, it runs on a 480 VAC supply and is specifically tailored for 3-phase systems. With a maximum input current of 27 A, it can effectively manage a motor capacity of 20 HP during standard use, while it can support up to 15 HP under heavy loading conditions.
This drive uses a Phase II control architecture, which, when paired with SynchLink, enhances its performance and connectivity. Communication is facilitated through ControlNet DPI, utilizing coaxial cable for reliable data transfer. It is equipped with safety features, including a safe-off function and compatibility with a second encoder, thus elevating operational safety.
For user interaction, the drive features an LCD display alongside a numeric keypad, making it user-friendly and straightforward to operate. The device has an enclosure rated IP20 / Type 1, which provides adequate protection for internal components from dust and accidental contact.
Accommodation for external components is also available, as the unit includes an installed brake IGBT while requiring an external brake resistor for optimal functionality. The EMC filter used within this drive meets CE compliance (89/336/EEC), ensuring that it adheres to stringent electromagnetic compatibility standards. In summary, the 20DD027A3EYNACBSE drive combines flexible functionality with essential safety features, making it suitable for a range of demanding applications.
