The Kinetics model SVRS-PF is a heavy
industrial, solid state, limited range,
closed loop regulation, SCR excitation
rectifier. The model SVRS-PF closed
the output feedback loop by use of
a vernier generated power factor signal
for the automatic adjustment of the
exciter output voltage to the motor
field to maintain a desired leading,
lagging or unity power factor value.
Kinetics’ power factor regulated
units incorporate a combination power
factor and voltage regulated system.
PF is regulated within an adjustable
minimum to maximum range. Outside
of the minimum and maximum range the
unit regulates output based on excitation
voltage to maintain the motor in synchronous
operation. If or when the motor power
factor value comes back within the
minimum to maximum range, the unit
automatically switches back to a power
factor regulated mode of operation.
The Kinetics dual mode of operation
system provides for stability in operation
where impulse, cycling or surge loading
is common such as compressors, rolling
mills, ball mills, and paper mill
grinders. The Kinetics power factor
regulated excitation system, with
or without a KinetSync digital logic
controller and annunciation module,
can be applied to reciprocating compressors.
A standard Kinetics excitation rectifier,
model SVRS-PF is designed and manufactured
with full current capacity rating
from 110% to 80% of the DC voltage
rating. Below 80% volts, the current
rating capacity is reduced directly
proportional to voltage. Extended
lower voltage range units and units
with field forcing capacity are available
upon request.
Standard units come with an output
adjustment potentiometer at the unit.
A local or remote output mode of operation
selection switch can be added as an
option for applications where output
adjustment from a remotely supplied
signal or remote location is desired.
Units are available in the 500 watt
to 2,000 Kw capacity range.
A standard SVRS-PF would include an
industrial free standing enclosure,
input circuit breaker or line fusing
for inputs above 600 volts, isolation
transformer with copper conductor,
heavy duty DC surge suppression for
highly inductive loads, DC ammeter
& voltmeter and semi-conductor
fuse monitoring indication lights.
For applications where re-using existing
enclosures will be re-used or supplied
by "other", Kinetics offers
open panel chassis and cell-in-cell
package.
Units are available in the 500 watts
to 2,000 Kw capacity range. As an
integrated manufacturer, Kinetics
has the manufacturing flexibility
to offer systems in single phase or
three phase AC input configurations.
Cautionary
note: when using a logic controller
by a manufacturer other than Kinetics,
check with the specific manufacturer
to determine if the controller is
suitable for power factor regulation
in a given application, such as a
reciprocating compressors.
The SVRS-PF
exciter can be provided with Kinetics’
solid state field application system,
Synchapp-SS and Kinetics’ digital
logic controller & annunciation
module, KinetSync-SR for brush type
motors. The KinetSync-NB is available
for brushless motors. |
