Overview

A contact-type variable autotransformer, servo motor and automatic control circuit continuously stabilize the supply. When mains voltage or load changes, a sampling/control circuit drives the servo motor to reposition the carbon brush and bring output voltage back to its rated value.

The text describes TND and TNS as updated products based on the SVC AC voltage-stabilizer series; the page heading and dimensional table are for TND single-phase units. Brochure describes an attractive exterior and economical design.

Applications

Office equipment, test equipment, medical equipment, industrial automation equipment, household appliances, lighting systems and communications systems.
