TYPICAL APPLICATIONS:
Capacitors
modules are intended for use in ventilation and
extraction
systems for regulation of three motor speeds with capacitor switching.
PRINCIPLE OF OPERATION:
By connecting the motor to a change-over switch, one
necting the motor to a change-over switch, one
necting the motor to a change-over switch, one
capacitor
circuit to other is activated, producing different combinations of
capacitance and
reactance
that result in three output levels.
