Parker's AC series of Variable Frequency Drives (VFDs) offers a new robust and scalable solution for industrial motor speed and torque control. From simple standalone applications to sophisticated, multi-axis feedback-driven systems, the new AC15, AC20, and AC30 series delivers a range of high performance, flexible, solutions that make it suitable for a broad array of industries including manufacturing, HVAC, packaging, and process automation.
While there are myriad options for VFDs from many manufacturers on the market, Parker’s AC Series VFDs stand out for their simplicity, reliability, and wide array of advanced features usually only found in more expensive products. Across the four models, power outputs from 0.37 kW up to 450 kW are supported. All three models are equipped with Ethernet for easy communication and programming. Additionally, all of the Parker AC Series feature Safe Torque Off (STO) for SIL2 and PLd rated safety circuits.
