Some types
use electromechanical components and others use electronic
components. Electronic reduced voltage starters are often
referred solid-state reduced voltage starters soft
starters.29
Random Access Memory Usually refers type semiconductor memory often used
(RAM) for temporary storage.

SIRIUS Soft Starters
Resistance property material circuit that opposes current flow.
ResistanceTemperature device used sense temperature that varies resistance as
Detector (RTD) temperature changes.The unit for
reactive power the var.
.The symbol for reactance “X. RAM requires the continual application
of power retain information. For some systems, battery
backup used prevent data program loss the event a
power outage.
Read Only Memory (ROM) Usually refers type semiconductor memory often used
for permanent storage data programs that not change.
Rectifier device circuit that converts alternating current direct
current.
There are variety reduced-voltage starters.
Reactive Power Power associated with inductance capacitance.
Resistance symbolized “R” and measured ohms.
Input
Rectifier
Output
Reduced-Voltage Starter type motor starter that applies less than the full-line
voltage three-phase induction motor while starting.
Reactance The opposition alternating current resulting from circuit
inductance and capacitance
