Step less Auto Variable Transformer. (SAVT)

Introduction:-

Stepless  Auto  Variable  transformers  called  after  (SAVT)  having  a moving Carbon Brush Arm. Sliding on Copper Conductor , Rotation of the Brush Arm by either manual or  motor  Driven deliver an output Voltage from 0 Volt to Input Voltage level or Higher than Input Voltage.

Single  Phase SAVT takes the input from 240 V - 50 Hz AC line and the output can be varied from 0-270 V. Single phase SVAT are available in projection  Mounting  and Flush  Mounting  types.  For  better cooling, SVAT  of  rating  above  28 amps are made in oil - cooled construction. Output of these SAVT can be varied from 0 to 270V input being 240V - 50 Hz AC.    
Ganged Assemblies of 3 coils, connected in star are available for 3 phase supply. Contact arm of these coils are connected to common shaft. 3 phase SAVT takes the input from 415 V - 50 Hz AC and the output can be varied from  0  to 470 V.  For  better cooling, 3 phase SAVT of rating above 28 amps are supplied in oil cooled construction.
Now we  can  provide  roller carbon brush assembly for long term trouble free operation of variac in range of 28 Amp. & above.

All  SAVT  are  available  in  open Type Construction for Servo Voltage Stabilizer Manufacturers only.
