Parker – AC20 Series – AC Variable Frequency Drive

The AC20 Advanced Compact Drive is a highly featured yet economical solution to general purpose motor control applications. AC20 provides speed or torque control in the power range 1.5 kW to 180 kW. Its compact dimensions house many features normally only associated with system drives, including sensorless vector mode for control of Permanent Magnet (PMAC) and AC induction motors, encoder feedback and IO expansion option cards, Safe Torque Off and an onboard Ethernet port that supports major industrial Ethernet protocols. AC20 provides the perfect solution for OEM machine builders looking for a compact, cost-effective drive without compromising on performance.

Simplicity
AC20 is designed to reduce the time and effort required to select, install, set up and commission Two variants of option card are available, and both are user installable/retrofittable. Minimal wiring requirements with two easily accessed terminal rails and removable power cable earthing brackets make AC20 fast and simple to install. All AC20 come with a high quantity of user configurable IO and a user disconnectable C3 EMC filter as standard. Programming and commissioning is made simple through its easy to use integrated keypad and the DSELite programming tool

Reliability
Proven technology and manufacturing techniques ensure AC20 has been engineered and built to deliver consistently outstanding levels of performance day in, day out - ensuring maximum uptime and productivity. Thanks to its conformally coated PCBs, AC20 is built to withstand C3 environments.

Compatibility
AC20 has been designed with system compatibility in mind. The compact footprint allows installation into existing spaces, while the IO count has been chosen to allow maximum possible flexibility. The internal block diagram is fully featured to enable replacement of legacy Parker inverters, and the onboard Ethernet communications protocols aid integration into wider systems. Retrofittable, plug-in communications cards cover all popular protocols and are simple to configure.

Applications
AC20 provides a no-fuss approach to general purpose industrial motor control applications across a wide range of industries, giving users the benefits of the inherent energy-saving properties of using a variable speed drive, as well as the improved reliability and extended service life benefits associated with smoother starting and stopping of regularly cycling loads.
