Variable Voltage Auto Transformers (Variac)

Indostat continuously variable voltage auto transformers, Indostab servo controlled voltage stabilisers, UPS systems, isolation transformers, inverters, etc., are products from Indu Power-Tech, an ISO 9001-2000 company. It has always believed in consistently providing top-notch products to the customers, which are well received by them. Applications: to obtain variable AC voltage from a fixed AC voltage, to obtain stabilised AC voltage from a varying input supply, in testing of electrical equipments where a gradually varying is a must to ensure non-destructive testing, to eliminate the possibility of high surges, for exact control of furnace and heater temperature. Range of products: 4 A to 700 A in various models and types, air cooled type variacs available up to 100 A. Indostat is a reliable name in continuously variable voltage auto-transformers, manufactured with state-of-art technology. This produces a steplessly variable voltage from available supply voltage. Characteristics: extremely low magnetising current due to use of selected material in toroidal form; easy to maintain and to handle; noiseless construction; smooth, specially ground silver plated brush track; production of distortion free replica of input wave-form; and specially made carbon brushes form material having the most desired features and limit regulations to achieve high efficiency. Models: Indostat continuously variable voltage auto-transformers are available in three different models: Flush type – for back of panel mounting (for air-cooled ratings only); Enclosed –for table/floor mounting (for air-cooled ratings only); and Oil cooled – Indostat of all ratings are available in oil cooled constructions suitable for highly corrosive or hazardous atmosphere, arduous duties involving high surge currents or short time overload capability requirement.
