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

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.
The front box is opened for access to the M6 terminals studs for connection as you require.

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