February 1, 1947

Regulated DC voltages at currents and stabilities previously available only with batteries are now possible through a new line of voltage regulation units, called Nobatrons, which have been announced by Sorensen & Company, Inc., 375 Fairfield Avenue, Stamford, Connecticut.

Nobatrons, available in six standard models, operate on a 95-125 volt AC source of 50 to 60 cycles and provide amperages of 5, 10 or 15 with output voltages of 6, 12 or 28 respectively. Regulation accuracy of one half of one percent, maximum ripple voltage (rms) of one percent and recovery time of one fifth of a second make Nobatrons ideally suited for critical applications where constant, unvarying DC voltages are required.

Among the more important uses for Nobatrons are in DC ammeter calibration in experimental, standardization and quality control laboratories, in photographic studios to replace batteries for furnishing power to light sources, in battery operated relays, in supplying current to filaments of DC amplifiers and in every other place where it is desirable to replace a battery to guarantee continuous regulated supply and to eliminate the difficulties of maintaining a power pack source.

Control features of the Nobatron line include an "on-off" switch, a voltage adjustment, a control circuit fuse and a pilot light. Models are available either for panel mounting or encased in a cabinet with a gray wrinkle finish.
