Auto Variable Transformers

Model No. ECT0008

Specifications: 

·    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 voltage

·  Zero to approx. 12% higher than the supply voltage

·    These auto transformers or dimmers are Suitable for indoor use on maximum ambient temperature of 45^oC.

·    Variable Auto Transformers are rated 240 volts Input and 0-270Volts 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.
