AC Motor Controller - LSI-LS7317

The LS7317 is a MOS circuit for controlling the speed of an AC motor. Five inputs are provided to select five speed/power levels between 40% and 96% of full power. A BOOST/ input is provided to override any selected power level with a jump to 99% of full power. A PULSE/ input provides for periodic two seconds on, two seconds off auto-pulse cycle for one minute. All these inputs require momentary activation which can very conveniently be produced by push-button dome or leaf switches. Phase synchronization of the external AC and the triac trigger is made with an internal PLL, with the AC signal being applied to the SYNC input of the LS7317. An OFF/ input is provided for turning the motor off with a momentary push-button switch. Note: This series has a minimum purchase requirement of 10 pieces, regardless of stock.
