Compact Drive Technology

Compact Drive Technology

The KL2791-xxxx AC motor speed controller is intended for direct connection of different low-power single-phase AC motors. The KL2791 enables speed reduction of typical motors such as capacitor motors, universal motors and shaded-pole motors. The required output power is specified via the process data. The output setting matches respective output value through targeted on and off switching at optimized times. This technique is particularly suitable for drives with quadratic load characteristic such as fans and pumps.

 

Special features:

  • direct motor connection
  • Leading edge phase control and full-wave control
  • Available rated voltage/power
    • 230 V AC/200 VA (KL2791, KL2791-0011 without power contacts)
