Eaton PowerXL DC1 Variable Frequency Drive DC1-349D5FB-A20N, 4 kW, 3-Phase, 400 V, 9.5 A, IP20, EMC Filter, Modbus RTU 169487

Controlling the speed of a three-phase motor without wasting energy or risking premature wear requires a drive that matches your motor's ratings and your control system. The Eaton PowerXL DC1-349D5FB-A20N variable frequency drive delivers 4 kW of power from a 380-480 V three-phase supply, with a rated output current of 9.5 A. Its integrated EMC filter and braking transistor simplify installation and reduce panel clutter.

Who is it for

This drive suits machine builders, panel builders, and maintenance engineers who need a compact, reliable speed controller for pumps, fans, conveyors, and other industrial applications. It is also a practical choice for retrofitting older motor starters with modern variable speed control.

Tips

When commissioning, set the motor parameters exactly as per the motor nameplate to ensure optimal performance and protection. Use shielded control cables and separate them from power cables to avoid interference. The integrated Modbus RTU allows direct connection to PLCs and HMIs for remote monitoring and speed commands.
