Variable Transformer, 30A - MVT8.1k/30A-1

This variable voltage autotransformer provide a trouble free and an efficient means of varying/controlling AC voltages. Variation of the output voltage is achieved by means of a brush arm with a carbon tip which rotates around a silver plated commutator.
This new range uses round carbon brushes, riding any imperfections, giving a smoother operation. They are superior to standard rectangular brushes which are fragile, suffer from breakages and cause a rough action over time.
This is supplied open-style for mounting in your own enclosure or equipment panel. Ensure users are suitably protected from this transformer during operation.

• Multiple round carbon brushes, low current density
• Excellent regulation, high efficiency, no waveform distortion.
• Low operating torque, smooth and linear output.
• Centre tap in winding for buck-boost applications.
