CONTROL AC SPEED W/DIODE

Controls of all kinds are integral parts of restaurant equipment operation. A control is a switch or other device by which a machine is regulated. A control may be manual or automatically operated. An electro-mechanical control typically consists of multiple relays, timers, and/or counters wired together on an enclosure panel. Electro-mechanical control is also referred to simply as "Relay Control", which is a more accurate term since solid state electronic relays, timers, and counters are standard components. Contactors, motor and compressor starters, valves, thermostats, and other output devices are used to turn on/off motors, indicator lights, heating elements, and other components used in the equipment.

A diode is a two-terminal electronic component that conducts current primarily in one direction (asymmetric conductance); it has low (ideally zero) resistance in one direction, and high (ideally infinite) resistance in the other. A semiconductor diode, the most commonly used type today, is a crystalline piece of semiconductor material with a junction connected to two electrical terminals. Semiconductor diodes were the first semiconductor electronic devices.
