Input ratings: Typical power-supply modules are designed and rated to operate with their inputs connected to lines delivering 105 to 125 Vac.

Disc motors are permanent-magnet stepping motors that exhibit performance comparable to that of hybrid motors.

Dc servomotors are normally used as prime movers in computers, numerically controlled machinery, or other applications where starts and stops are made quickly and accurately.

Operational supplies are frequently used to regulate the intensity of heavy-duty light sources such as xenon or arc lamps.

Movement differential:For basic and plunger-actuated switches, this is stated as a range.

Power supplies available today offer more than just a source of voltage or current.

Industrial applications use direct current motors because the speed-torque relationship can be varied to almost any useful form -- for both motor and regeneration applications in either direction of rotation.

Self-protecting starters (SPSs) were first introduced to the U.

A typical linear encoder consists of a scanning unit and a scale.

Power-circuit modules containing several power semiconductor switching devices can reshape ac power into other required forms and often have current ratings from 30 to 50 A.

Incandescent miniature and subminiature lamps are used in applications requiring high brightness, a wide viewing angle, and a variety of display colors.

Input/output devices are the interface between the controller and the controlled system.
