Purevolt Products Pvt. Ltd

Model Number: Variable Auto Transformer 001 Brand Name: PUREVOLT Key Specifications/Special Features: Technical specifications of variable transformer:Rated for 240V A.C 50/60Hz, single phase supply and three phase model for 415V A.C. 50/60Hz three phase 4 wire supply.The output voltage of these toroidal or variable transformer can be varied smoothly over two ranges:Zero to full supply voltageZero to approx. 12% higher than the supply voltageThese auto transformers or dimmers are suitable for indoor use on maximum ambient temperature of 45°C.Variable auto transformers - Variacs are rated to work at 240 volts input and supply 0-270V output. Similarly, three 240-volt units are ganged in a star connection to result in a 470-volt line-to-line three-phase assembly. For 480-volt open delta applications, two 240-volt units are used in series in each of the two legs of the open delta assembly. In any of the above voltage applications, higher current requirements are met by paralleling two or more units in the ganged assembly.
Rating available:2 amps to1800 amps
Air/oil cooled and single/three phase (special ranges also available on request)
