SIRIUS Soft Starters
Resistance property material circuit that opposes current flow.
Read Only Memory (ROM) Usually refers type semiconductor memory often used
for permanent storage data programs that not change.
ResistanceTemperature device used sense temperature that varies resistance as
Detector (RTD) temperature changes.

Reduced-Voltage Starter type motor starter that applies less than the full-line
voltage three-phase induction motor while starting.The symbol for reactance “X.
There are variety reduced-voltage starters. Electronic reduced voltage starters are often
referred solid-state reduced voltage starters soft
starters.
Reactance The opposition alternating current resulting from circuit
inductance and capacitance.
Resistance symbolized “R” and measured ohms. RAM requires the continual application
of power retain information. For some systems, battery
backup used prevent data program loss the event a
power outage.
Reactive Power Power associated with inductance capacitance
