Energy-saving controller

The Powerboss Integra Intelligent Motor Controller is designed to control electric motors and can achieve energy savings.

The thyristors are switched on at a calculated point in the waveform; the closer this is to the zero crossing point in the waveform, the smaller the value of the current that will be allowed to flow.

Using this principle and by connecting two thyristors in anti-parallel to each of the phase connections of a motor, the controller continuously adjusts the voltage to the motor terminals by precisely controlling the thyristor's switch on points.

Continuous dynamic control is applied to the motor through a microcontroller embedded with software. Used on the right application, a saving of more than 28% is claimed to be achieved.

The unit is also designed to consistently monitor the flux from the motor and thus is able to maximise potential savings without stalling the application, adversely reducing its speed or altering its ability to effectively carry out its job of work at any point in the application duty cycle.

Available in single phase up to 10 kW and in three phase from 4 up to 650 kW in 415 V and from 200 up to 1500 kW in 1100 V.
