AC Speed Control, Chassis/No Enclosure, 120VAC Supply, 10A, .25" Male QC Supply Connection and Output Connection, Includes Mounting Hardware

The 55/57 series are cost-effective and compact triac variable AC voltage supplies that are manufactured especially for the vibratory feeder, fan, pump, heating, and lighting industries. All models feature single-phase AC input and fully variable AC output. The enclosed version comes with a rugged housing, power on/off switch, power on indicator lamp, front access fuse, as well as convenient input and output cords and plugs. The heart of the control is a triac fired in a manner to adjust phase and thereby vary speed. The 55 Series is designed to work with shaded pole, permanent split capacitor, permanent split-phase, universal motors or any resistive load. It is not designed for capacitor start motors. It also can be used with heating elements as a simple temperature control. Open chassis models include speed pot knob and dial. The 55/57 Series AC Motor Speed control is a triac based single phase variable voltage supply. It is used primarily with single phase AC motors and universal motors that ARE NOT CAPACITOR START designs. 55AC10E- Enclosed, NEMA 1, 120V, 10 Amp, 1hp 55AC15E- Enclosed, NEMA 1, 120V, 15 Amp, 1.5hp 57AC10E- Enclosed, NEMA 1, 240V, 10 Amp, 2hp 57AC15E- Enclosed, NEMA 1, 240V, 15 Amp, 2.5hp Change E to C on any of the above for the chassis versions
