    Description
    APPLICATIONS DESIGN AND CONTROL
    • VFED-…-TA series controllers or inverters are designed for frequency control of three-phase asynchronous AC motors.
    • Speed control is effected by means of variation of supplied voltage frequency.
    • Applied for air capacity control of three phase motors.
    • The controller casing is made of flame-retardant thermoplastic.
    • The assembly transforms voltage of 220V, 50Hz supply mains into output impulse voltage with the frequency 3Hz to 400 Hz.
    • Motor rotor is powered with simple sinusoidal current and has the rotation speed as a function of the supplied voltage frequency.
    • Single-phase 220V, 50Hz power is supplied to the frequency controller inlet.
    • Three-phase voltage with the frequency up to 400 Hz for asynchronous motor supply is generated at the controller outlet.
    MOUNTING
    • The controller is designed for indoor mounting.
    • Installation shall be performed with respect to the free air circulation for inner circuit cooling.
    • The controller is for vertical installation.
    • Do not install the controller above the heaters and in bad air convection areas.
    CONTROL BY MEANS OF EXTERNAL DEVICE
    • Power output variation as a function of the external control signal 0…10V or 4-20 mA over the range set during the controller adjustment.
    • The external device is connected through RS-232 serial port.
