Carroll & Meynell 1 Phase 4.9kVA Variac, 1 Output, 240V

Carroll & Meynell MVT Open Transformer

Carroll & Meynell variable autotransformers have variable voltages and are ideal for controlling AC voltages. The rotating arm with a carbon brush changes the output voltage.
These variacs feature round carbon brushes, riding any imperfections, offering a smoother operation. The round carbon brushes last the lifetime of the unit and are more robust than standard rectangular brushes, which are susceptible to breakages. These variacs have high efficiency and excellent regulation with no waveform distortion.

Features

A round carbon brush offers low current density
Low magnetising current
