Get a firm handle on how fast your industrial motors run with this inverter drive from Siemens. It works by converting the input AC supply voltage to your motor to a DC value and then back to an AC output with variable frequency, so speed control stays in your hands. Thanks to a current rating of 16.5A and a 7.5kW power rating, this piece of kit can handle heavy-duty applications without breaking a sweat. For optimal performance, it comes with a built-in fan to ensure that it stays cool in the heat of the moment. You'll find it used to manage high-pressure compressors in food processing industries, as well as conveyor drives on assembly lines.

• Broad operating temperature range between -10°C and +60°C for use in demanding conditions
• IP20 rating means it's protected from anything larger than 12mm, such as wires and hand tools
• Light weight of 4kg for easy handling during installation

For versatility, this unit can be hoisted on a wall frame or installed side-by-side with other control devices in your panel.
