Our Single Phase Enclosed Type Variable Autotransformer is ideally suitable on a Test bench. It is provided with digital voltmeter and 0-20A Ammeter. It becomes very convenient for the operator to carry on testing as both output voltage & current can be measured.
The picture above is a motorized version of Single Phase Variable Autotransformer (Variac). We manufacture it using top quality motors, Micro Switches and with rugged construction. The side studs and center shaft are well insulated from each other to avoid completion of magnetic circuit. Our Single Phase Variable Autotransformer Models available are 2 Amp, 4 Amp, 6 Amp, & up to 35 Amp. For Models above 40 Amp, we use side wiping contacts. The commutator surface on these coils is machine processed and hence is very even and smooth. This ensures very less torque for the motor, thereby enhancing its life.
