KL2791 | 1-channel AC motor speed controller 230 V AC, 200 VA
The KL2791 AC motor speed controller is designed for direct connection of different single-phase AC motors with small capacity. The KL2791 enables speed reduction of typical motors such as capacitor motors, universal motors and shaded-pole motors. The required output is specified via the process data. The output setting matches respective output value through targeted on and off switching at optimised times. This technique is particularly suitable for drives with quadratic load characteristic such as fans and pumps.
