Variable Auto Transformer
Variable Auto Transformer is a device that delivers the voltage from 0 to 270V in single phase and 0 to 470 in 3-phase continuously without any break in output voltage. This variation is obtained by the turning of the knob in less than a complete circle rotation. These units are very compact and very economical compared to the conventional transformers. The company manufactures various capacities of Power-O stat units of 2, 4, 8, 10, 15, 28, 40, 50, 60, 100, 150 and 200 A. These capacities are manufactured for single-phase and three-phase units. In single phase, from 2 to 100 A, only one core is used and above 100 to 200A two units up to 100 A, three units are random mounted and the common shaft that drives the carbon for three cores simultaneously give equal voltage across each phase. Above 100A, 6 cores are employed and they are mechanically arranged in such a way that across each phase, they deliver equal voltages. In three phases, the units are rated for 415V, 3-phases with the output of 0-470V, 50/60 Hz. It is used to obtain variable DC voltage for electroplating sets, to vary the speed of DC motors either by hand operation or remote control by using stepper motor, to manufacture servo-controlled voltage stabilizers up to 600 kVA by incorporating stepper motors, to control and regulate the temperatures of various types of furnaces & ovens, to make big capacity floating rectifiers for telephone exchanges, to control the lighting of theatres, auditorium, and to make HV test sets, oil test sets and meter test benches. South Eastern Equipment Co offers Power-O-Stat.
