Read Only Memory (ROM) Usually refers type semiconductor memory often used
for permanent storage data programs that not change. Electronic reduced voltage starters are often
referred solid-state reduced voltage starters soft
starters. RAM requires the continual application
of power retain information.
ResistanceTemperature device used sense temperature that varies resistance as
Detector (RTD) temperature changes.

The unit for reactance the ohm.The symbol for reactance “X.
Reactive Power Power associated with inductance capacitance.
Rectifier device circuit that converts alternating current direct
current.The unit for
reactive power the var.
.
Resistance symbolized “R” and measured ohms. For some systems, battery
backup used prevent data program loss the event a
power outage.29
Random Access Memory Usually refers type semiconductor memory often used
(RAM) for temporary storage.

Output
Reduced-Voltage Starter type motor starter that applies less than the full-line
voltage three-phase induction motor while starting. Some types
use electromechanical components and others use electronic
components.
Reactance The opposition alternating current resulting from circuit
inductance and capacitance.
There are variety reduced-voltage starters.
