In many industrial nations, electric motors account for more than half of the electricity consumption so that they offer enormous energy saving potential. Speed control can easily reduce excess energy requirements.
The KL2791 Bus Terminal from Beckhoff is suitable for use as a speed controller for direct connection of single-phase AC motors up to 100 W. Besides the saving of energy, a decrease in speed also offers noise reduction and an increase in the service life of the motor. The module facilitates speed control between 10 and 100% for capacitor, universal and shaded-pole motors and is particularly suitable for drives with quadratic load characteristic such as fans and pumps.
The KL2791 Bus Terminal can control the speed of single-phase AC motors up to 100 W
The compact controller is housed in a standard 12 mm bus terminal unit and can be used in any bus system supported by the Beckhoff Bus Terminal system. The set value for the motor speed is specified by a 16-bit value and the motor is switched on and off with a practice-proven mains-synchronous pattern, so that the motor consumes less power.
