5-Speed digital controller with autotransformer for single-phase motor
These digital autotransformer controllers allow you to vary the speed of a two wires single- phase induction motor (typically designed for air intake applications) in a simple and practical way using the keyboard on the front panel of the device.
WARNINGS:
• Before installing and plugging the device into the mains, check the integrity of the appliance, check that the specifications indicated on the data plate and the technical characteristics explained on this manual correspond to those of the electrical mains system, of motor of auxiliary output (ex. gas solenoid valve).
• Always use high quality and suitable section electric cables wire to connect the regulator to the mains and to loads.
• During the installation of the appliancet pay particular attention not to damage the sheath of the power cable.
• If the power cable (not supplied) is damaged, it must be replaced by authorized personnel, using an equal or better quality cable.
• We recommend that you keep within the device the lenghts cable short to avoid their contact with particular components that could reach high temperatures.
• lt is advised to use cable glands (at least IP55 or IP68) or suitable fittings that have enough space for the cables to exit but avoid seepage of moisture and condensation.
• Install the regulator in ventilated places and away from sources of heat, especially if the current load absorption are close to the maximum declared.
• Be sure to connect the ground wire of the motors (or the chassis of the motors) to the main board and the latter one to the grounding system of the network.
