Energy saving motor controller
POWERBOSS Integra intelligent motor controller, available from Control Supplies , is designed to control electric motors and achieve an ROI (return on investment) in energy saving flowing through the thyristors, by controlling the voltage.
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, Powerboss 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 micro controller embedded with unique software. Used on the right application, a saving of more than 28% can be achieved.
The Powerboss 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.
Powerboss works hard on:
1. Assessing the load on the motor every cycle of the supply.
2. Adjusting the voltage proportionately to the load.
3. Giving the motor intelligence.
4. Putting the user in control.
Available in single-phase up to 10kW and in three-phase from 4kW up to 650kW in 415V and from 200kW up to 1500kW in 1100V.
