This is a handy bench tool for testing or controlling AC-powered devices. It's a variable AC voltage supply (sometimes called a variac or variable transformer). You plug it into a standard 120V wall outlet, and it gives you a dial to adjust the output voltage anywhere from 0 volts all the way up to 120 volts. The maximum current it can handle is 15 amps (with a 1.5 HP motor rating). What's it for? Great for testing equipment at different voltages, controlling the speed of universal, shaded pole, or PSC (Permanent Split Capacitor) motors – think fans, blowers, or small pumps to make them run slower or faster. You can also use it with resistive loads like dimming heaters or incandescent lights. Important: It's NOT designed for capacitor-start motors. It has a power switch, an indicator light, an 18-inch power cord with a plug, an 8-inch output cord with a female receptacle, and fuse protection. The unit itself is compact, about 5.5\ x 4\ x 3.8\. A useful piece of gear for hobbyists, technicians, or in a workshop for all sorts of AC power experiments and controls.
