The unit for
reactive power the var.
Reactive Power Power associated with inductance capacitance.29
Random Access Memory Usually refers type semiconductor memory often used
(RAM) for temporary storage.
Reactance The opposition alternating current resulting from circuit
inductance and capacitance. Some types
use electromechanical components and others use electronic
components.
Read Only Memory (ROM) Usually refers type semiconductor memory often used
for permanent storage data programs that not change. RAM requires the continual application
of power retain information.
Resistance symbolized “R” and measured ohms.
3RW30/31 3RW40 3RW44
SIRIUS Soft Starters
Resistance property material circuit that opposes current flow.
ResistanceTemperature device used sense temperature that varies resistance as
Detector (RTD) temperature changes.
Input
Rectifier
Output
Reduced-Voltage Starter type motor starter that applies less than the full-line
voltage three-phase induction motor while starting.
Rectifier device circuit that converts alternating current direct
current. For some systems, battery
backup used prevent data program loss the event a
power outage.
There are variety reduced-voltage starters.The symbol for reactance “X.
”
The unit for reactance the ohm. Electronic reduced voltage starters are often
referred solid-state reduced voltage starters soft
starters.
