The Kinetics model SVRS-CR is a heavy industrial, solid state, limited operating range, closed loop regulation, SCR excitation rectifier. The model SVRS-CR is configured with the DC feedback loop closed on the rectifier output current. The excitation current from the regulated rectifier to the motor field can be adjusted while the motor is running and synchronized via an operator’s control potentiometer. Holding the excitation current constant, at a set point, permits the voltage to fluctuate with changes in field resistance associated with motor loading and field winding temperature. The highly reliable Kinetics regulator will hold the DC current within +/- 1% of the desired DC output. Output current is set by an infinitely variable adjustment potentiometer. 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.

A standard unit is designed with current capacity from 110% to 80% of the DC voltage rating. Below 80% volts, the current capacity is reduced directly proportional to voltage. Extended lower range units and units with field forcing capacity are available upon request.

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-CR 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, DC surge suppression for highly inductive loads, DC ammeter & voltmeter and semi-conductor fuse monitoring indication lights. For applications where the existing enclosure will be re-used or an enclosure provided by "other", Kinetics offers open panel chassis and cell-in-cell packaging.

The SVR-CR 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.
