The PowerFlex 70 series includes the 20AD027C5AYYANG0, an AC variable frequency drive engineered for precise motor control. This unit operates with a normal-duty capacity of 20 horsepower, and it can efficiently handle up to 15 horsepower under heavy-duty applications. An input voltage of 480 VAC in a three-phase configuration ensures reliable performance in various industrial setups.

The drive is designed for wall or machine mounting, encased in an IP66/NEMA 4X/12 enclosure. Thus, it meets the requirements for robust environments, safeguarding against dust and moisture ingress. Users interact with the drive via an LCD programming terminal, but it lacks a dedicated human interface module for direct command control.

An integral aspect of the drive is its IGBT dynamic braking system, paired with an internal resistor assembly that allows for effective dynamic braking in control applications. In terms of electromagnetic compliance, it features a dual-stage EMC filter that adheres to CE 89/336/EEC directives, significantly minimizing electromagnetic interference. However, the drive does not come with any preinstalled network modules for communication.

Advanced logic functions for parameterization enhance operational versatility, enabling customized control strategies for specific applications. The feedback system is organized in an open-loop configuration, which does not include an integrated feedback mechanism. Notably, the drive incorporates a Safe Torque Off (STO) safety circuit, contributing to operational safety. The emissions classification indicates that it is designed to operate within a filtered emission category, ensuring reduced electromagnetic emissions.
