Variable frequency drives A550

The A550 series frequency inverter from VYBO Electric is a versatile integrated unit that belongs in economy class. It is characterized by the transparency of its control elements and its simplicity. It is perfectly adapted to clients requirements and has been developed on the basis of years of experience and user feedback. The A550 is pre-programmed and ready for immediate use. All you have to do is properly plug it into the mains. It can be controlled directly from the panel or even externally. Switching the frequency converter on is easy, just press the START button and rotate the built-in control knob. This causes the motor to accelerate or decelerate automatically.

STANDARD A550 is a practical, simple frequency converter designed for standard applications. It is designed so that its operation can be handled by ordinary users. The A550 is already factory-programmed for the basic application, so it only needs to be connected properly and can work immediately. The A550 frequency inverter can operate at an output frequency of up to 400 Hz. Control is scalar V/F. As standard, the A550 has a built-in brake unit (except some models), DC braking, PID, PLC, MODBUS communication, EMS safety stop, PTC motor or thermocontact connection, torque booster, AVR, etc. The A550 has the option of connecting an external control panel with a cable up to approx. 50 m. Standards IEC 61800-5-1, IEC 61800-3 (Environment 1 and 2, Category C2). Integrated with 4 digital inputs, 1 analog 0-10 V input and 4-20 mA, 1 multifunction relay output, etc.
