VARIABLE AUTO\u00a0TRANSFORMERS<\/p>\n
Variac or variable auto transformer manufactured by teczhar is available with AC control voltage controls that offer continuous AC voltage supply. Variac ensures a distortion free output that is suitable for sensitive electronic appliances and equipments in residential areas and industries. Manufactured with cutting-edge technology, these auto transformers ensure a consistent linear regulation of AC voltage to provide high output and negligible waveform distortion. It is suitable way of controlling current, light, heat and motor speed with a voltage factor. This transformer finds its wide applications in Auditorium, hotels, conference hall, laboratories, College & universities, Welding equipments, Servo stabilizer, rectifiers, battery charger and Testing instruments.<\/p>\n
CONSTRUCTION<\/p>\n
There is a single layer winding on toroidal core of high-grade cold rolled grain oriented (CRGO) steel<\/p>\n
A contact arm with a carbon brush is fitted on the centre shaft<\/p>\n
A special durable contact surface is made on one side of the copper winding and a specially finished carbon brush slide smoothly on the surface<\/p>\n
As the control knob is rotated, the carbon brush slides over the winding<\/p>\n
FEATURES<\/p>\n
These step-up and step-down transformers are widely used for:<\/strong><\/p>\n Can enhance the output voltage in excess of twice the input voltage<\/p>\n Low temperature rise<\/p>\n Any desired voltage within the maximum range can be obtained by adjusting the carbon brush<\/p>\n Wide assortment of current rating 4 Amp. To 1200 Amp<\/p>\n Calibrated dial show approximately output voltage at no load<\/p>\n Spare carbon brushes provided up to 28 Amp<\/p>\n The contact arm can be moved both manually and by motor<\/p>\n High quality carbon brush<\/p>\n Delivers an output voltage from 0 to above line voltage<\/p>\n Step-less voltage control<\/p>\n Constructed with 99.9% pure copper<\/p>\n Short time overload capacity<\/p>\n High grade CRGO steel is used for constructing coils<\/p>\n Maintenance cost<\/p>\n APPLICATION<\/p>\n Auditorium, hotels, conference hall, laboratories etc.<\/p>\n Testing instruments<\/p>\n Servo stabilizer, rectifiers, battery charger<\/p>\n College & universities<\/p>\n Welding equipments<\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" CONSTRUCTION<\/p>\n There is a single layer winding on toroidal core of high-grade cold rolled grain oriented (CRGO) steel<\/p>\n A contact arm with a carbon brush is fitted on the centre shaft<\/p>\n A special durable contact surface is made on one side of the copper winding and a specially finished carbon brush slide smoothly on the surface<\/p>\n As the control knob is rotated, the carbon brush slides over the winding<\/p>\n","protected":false},"featured_media":8798,"comment_status":"open","ping_status":"closed","template":"","meta":{"om_disable_all_campaigns":false,"_themeisle_gutenberg_block_has_review":false},"product_cat":[131],"product_tag":[],"_links":{"self":[{"href":"https:\/\/www.teczhar.com\/index.php?rest_route=\/wp\/v2\/product\/8796"}],"collection":[{"href":"https:\/\/www.teczhar.com\/index.php?rest_route=\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.teczhar.com\/index.php?rest_route=\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/www.teczhar.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=8796"}],"version-history":[{"count":1,"href":"https:\/\/www.teczhar.com\/index.php?rest_route=\/wp\/v2\/product\/8796\/revisions"}],"predecessor-version":[{"id":8799,"href":"https:\/\/www.teczhar.com\/index.php?rest_route=\/wp\/v2\/product\/8796\/revisions\/8799"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.teczhar.com\/index.php?rest_route=\/wp\/v2\/media\/8798"}],"wp:attachment":[{"href":"https:\/\/www.teczhar.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=8796"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.teczhar.com\/index.php?rest_route=%2Fwp%2Fv2%2Fproduct_cat&post=8796"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.teczhar.com\/index.php?rest_route=%2Fwp%2Fv2%2Fproduct_tag&post=8796"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
