VLG30004A480 Lovato THREE PHASE AC DRIVE 380-480VAC 0.4KW

Why Choose the Lovato VLG30004A480 Variable Speed Drive?

The Lovato VLG30004A480 is a compact and versatile three-phase AC variable speed drive (VSD) designed for precise speed and torque control of asynchronous motors in industrial machinery and automation systems. As part of the Lovato VLG3 variable speed drive series, it combines flexible motor-control functions, integrated communications and a compact monoblock design for efficient machine and control-panel integration.

The VLG30004A480 supports multiple motor-control modes including linear V/f, quadratic V/f, custom V/f and sensorless vector control. Integrated functions such as PID control, autotuning, slip compensation, flying restart, DC braking and preset speeds provide the flexibility required for a wide range of machinery, pumps, fans, conveyors and automated equipment.

With a rated output power of 0.4 kW, rated output current of 1.3 A and a three-phase 380–480 V AC supply, the VLG30004A480 is designed for smaller industrial motors. It also features an integrated Category C3 EMC suppressor, RS485 communication with Modbus RTU and a built-in brake chopper for comprehensive industrial motor control.
