The Kinetics model SVRS is a heavy industrial, solid state, limited operating range, closed loop regulation, SCR excitation rectifier. The model SVRS is configured with the DC feedback loop closed on the rectifier output voltage. The excitation voltage from the regulated rectifier to the motor field can be adjusted while the is motor running and synchronized via an operator’s control potentiometer. The highly reliable Kinetics regulation controller continuously adjusts the power semi-conductors to maintain the exciter output voltage within +/-1% of the desired DC output voltage.
A standard Kinetics excitation rectifier, model SVRS, is designed and manufactured with full current rating capacity from 110% to 80% of the DC voltage rating. Below 80% volts, the current capacity is reduced directly proportional to voltage. Extended range lower range units and units with field forcing capacity are available upon request.
Standard units come with a DC output adjustment potentiometer at the unit. A local or remote output mode of operation selection switch can be added as an option feature for applications where adjustment from a remote location is desired.
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.
A standard SVRS system would include an industrial freestanding enclosure, input circuit breaker or line fusing for inputs above 600 volts, isolation transformer with copper conductor, conservatively sized SCR regulator, heavy duty DC surge suppression for inductive loads, DC ammeter & voltmeter and semi-conductor fuse monitoring indication lights. For applications where the existing enclosure will be re-used or the enclosure will be provided by "other", Kinetics offers open panel chassis or cell-in-cell packaging.
The SVRS exciter can be provided with Kinetics’ solid state field application system, Synchapp-SS and Kinetics’ digital logic controller and annunciation module, KinetSync-SR for brush type motors. The KinetSync-NB is available for brushless motors.
