ABOUT US

An official Varsan said "Our firm was established in 1980 in Küçükçekmece, İstanbul.Until 1990 it offered variable transformers (Variac). Reosta, Centrifugal Gold mould machines,Serve automatic regulators from 1 KVA to 750 KVA, Troid transformers and various products to Turkish industry.

But, 1990 we stopped these productions except variable transformers (Variac) in order to achieve world quality and we directed to produce according to keeps world standards inside our new factory build on a 3.000 m square covered area. Our products are produced by band methods and transformers from 0,5 KVA to 15 KVA H18 and M5 silica metal sheet

Besides assuring plentiful availability of standart spare parts; also you can use repair and maintenance services.

We can also produce every kind of variable transformers and special propose production on order.



PRODUCTS





WE CAN ALSO PRODUCE EVERY KIND OF VARIABLE TRANSFORMERS AND SPECIAL PURPOSE PRODUCTION ON ORDER



ISSUES TO CONSIDER BEFORE USE

  • Never touch to variac while electricity.
  • Do not remove variac components without qualified technicians.
  • Get contact with the manufacturer if are there any fault.
  • Do not use the rover tip as inlet.
  • Use a dry swab during variac cleaning.
  • Do not use chemicals for cleaning the variac.
  • Use variac in the recommended voltages.
  • Installation must be done by qualified technicians with electrical knowledge.
  • For protect to variac, use fuse protection on variac input.
  • Environmental humidity where variac is located shouldn't be higher than 80%
  • Keep away the variac from water, dust or other similar environmental factors.






WORKING PRINCIPLE OF THE VARIACS

Description: (VARIAC – Variable Transformer)

The variacs can run with only specific section of primary winding or completely of winding, same like secondary winding. Also it works in same magnetic influences.

Structure:

There are two windings (primary and secondary) in the traditional transformers. But in the variable transformers there are only single winding, it works like primary and secondary winding. With this single winding lost of the reactances get minimize.

The variacs can use like a potentiometers.





For Example;
S = 10A x 220V
S = 2200 VA
S = 2,2 KVA
*** Please do not pass over determined maximum variac output current even if changes of variac output voltage, because of the variacs winding with single and fixed dimension copper.





USER SERVICE INSTRUCTIONS

After cut off the power;
Clean dusts with compressed air.
Clean to carbon brush contact areas on variac surface with fine sandpaper.
Check up all the screws and nuts against loosening.



INSTALLATION INSTRUCTIONS

For 1 KVA to 5 KVA
Use M6 bolt nuts in variac polyester base during installation and Complete the electrical connection like below diagram.

For 6,5 KVA to 15 KVA
Use M6 bolt nuts in variac aluminum base during installation and Complete the electrical connection like below diagram.
