Variable Auto-transformer- (Dimmer Or Variac)

We offer a wide range of Variable auto- Transformer- (Dimmer or Variac) to our customers. The importance of continuously variable voltage in Electrical Engg. Works cannot be overemphasised, ARKAY
'VARISTAT' are made to make such continuously variable voltage most easily available.
The intrinsic quality control check-ups under the supervision of highly experienced engineers ensures the ruggedness and reliability of operation

Input Voltage: The voltage that should be applied to the input terminals to make the dial calibration
correct is 240v, 50Hz, 415v, 50Hz

Output Voltage: The output voltage from the varistat is continuously adjustable from zero to 12.5%
above the line voltage (i.e. 270V or 470V). The dial reads the approximate voltage.

No load current: Less than 2% of full load

-Construction: Both single and three phase units are supplied enclosed in sheet metal covers, unless
asked for open type construction for panel mounting,oil cooled units are supplied in sheet-metal tanks with
or without cooling radiators.

-Current ratings: (single wound type)
