SEW-Eurodrive is supplementing its portfolio of drive electronics with the new frequency inverter, Movi 4R-U 'with IP54 degree of protection, which enables it to be mounted outside of a control cabinet. The frequency converter offers simple speed control of asynchronous motors, supported by a new, simple and intuitive operating concept, based on a control knob in a combination of rotary switch and push button.

The new product range covers the performance range from 0,25 to 1,1 kW (3x AC 400 V) or 0,25 to 0,55 kW (1 / 3x AC 230 V). Commissioning, setpoint specification and operating status including warning messages are covered by the operating concept; external PC software for operation is not necessary.

With the control button, the settings of all device parameters can be carried out via only two menu levels. The colored status LED indicates the status of the device and informs directly about the cause of the error in the event of a fault. The supplied operating card allows the user to handle the entire commissioning and fault diagnosis without external help or additional product documentation.

The device consists of a maximum of four main components, which are held together only by a screw. The frequency converter can be disassembled into its four main components in a few simple steps: aluminum housing, operating unit, internal power unit and fan.
