The KL2791 bus terminal efficiently controls single-phase AC motors.
The device permits direct connection of small, 1-A, single-phase 120-V, 60-Hz motors. The terminal reduces energy use of capacitor, universal, and shaded pole motors as well as drives with quadratic load characteristics such as fans and pumps. Motor speed is specified by a 16-bit value. With the terminal, the motor is switched on and off with a mains synchronous pattern so the motor consumes less power.
