{"title":"Variable Frequency Drives","description":"\u003ch5\u003eVariable frequency drives for variable-speed fans\u003c\/h5\u003e\u003cp\u003eVariable frequency drives enable stepless speed control of electric motors and are therefore an important tool for energy-efficient extraction and ventilation systems. Instead of running fans continuously at full power, the speed can be adjusted to match the actual air demand. This reduces unnecessary energy consumption and allows for significantly more flexible system control.\u003c\/p\u003e\u003cp\u003eIn this category, you will find variable frequency drives for various motor power ratings and applications in extraction and air technology. Depending on the model, setpoints can be specified via potentiometers, sensors, external signals, or higher-level control systems. Functions such as soft start, ramp times, fault messages, and motor protection may also be part of the system.\u003c\/p\u003e\u003cp\u003eWhen selecting a variable frequency drive, the motor power, line voltage, rated current, control range, and installation conditions must be compatible. Equally important are the ambient temperature, protection class, and the desired control method. Additional measures may be necessary for longer motor leads or special EMC requirements. A technically sound design ensures that the fan, motor, and drive work together reliably.\u003c\/p\u003e\u003cdiv style=\"background:#f5f5f5;border-radius:10px;padding:18px;margin:22px 0;\"\u003e\n\u003ch5\u003eYour Benefits\u003c\/h5\u003e\n\u003cp style=\"margin:0;\"\u003e✅ Demand-based speed control\u003c\/p\u003e\n\u003cp style=\"margin:0;\"\u003e✅ Lower energy consumption at partial load\u003c\/p\u003e\n\u003cp style=\"margin:0;\"\u003e✅ Smooth motor start-up and flexible operating modes\u003c\/p\u003e\n\u003cp style=\"margin:0;\"\u003e✅ Can be combined with sensors and controllers\u003c\/p\u003e\n\u003cp style=\"margin:0;\"\u003e✅ Better adjustment of the flow rate to the process\u003c\/p\u003e\n\u003c\/div\u003e","products":[],"url":"https:\/\/strahltechnik-express.de\/en-lu\/collections\/frequenzumrichter.oembed","provider":"ABS Strahltechnik","version":"1.0","type":"link"}
