The Allen Bradley 20DD027A0NYNANANE, part of the PowerFlex 700S series, is an AC drive tailored for various industrial applications. This unit operates from a 480 V AC, 3-phase, 60 Hz input. It provides a robust power capacity of 20 HP under normal duty conditions and 15 HP for heavier loads. The continuous output current capability reaches 27 A when connected to a 650 V DC bus.
For operational safety, this drive features overvoltage trip points set at 600 V AC and 810 V DC. Additionally, the undervoltage trip settings can be adjusted by the user according to specific application needs. Integrated into the design is an on-board brake IGBT, which improves braking performance. The system also maintains a nominal DC-bus voltage of 648 V DC, ensuring stability during operation.
In terms of noise management, the drive utilizes an internal EMC filter and a common-mode choke to suppress electromagnetic interference effectively. Users can select the switching frequency, which ranges from 2 kHz to 10 kHz, with a factory default of 4 kHz.
The drive’s control architecture features Phase II control combined with an expanded cassette slot, enhancing flexibility for various applications. It comes equipped with a total of 6 digital inputs and 2 digital outputs, as well as 3 analog inputs and 2 analog outputs to facilitate comprehensive control and monitoring capabilities.
Notably, this AC drive boasts an impressive full-load efficiency of 97.5% at rated current and voltage. The enclosure is rated IP20 per NEMA Type 1 standards, ensuring adequate protection for indoor applications.
