Carroll & Meynell Auto-Transformer 3 Phase 4.2 kVA 415 V Manual Operation Free Stand MVT4.2k/5A-3E

Carroll & Meynell MVT4.2k/5A-3E is a 3 phase auto-transformer with a rated power of 4.2 kVA and a primary voltage of 415 V suitable for industrial and laboratory AC voltage control applications. This model is designed for manual operation and features a free stand mount, ensuring flexible placement.

Constructed with an enclosed design, it protects internal components while enabling reliable performance in demanding environments. The auto-transformer employs a star vector configuration with three single phase variacs mounted on a common shaft. The use of round carbon brushes provides smooth, low-torque operation and extends service life by minimizing wear and waveform distortion.

Operating within a frequency range from 50 Hz to 60 Hz, the transformer offers excellent regulation and high efficiency, delivering a continuously variable alternating current output voltage. The inclusion of a centre tap in the winding allows for buck-boost applications. Termination is accomplished via clamp terminals for secure connection.

Key technical dimensions include a length of 245 mm, width of 250 mm, depth of 595 mm, and an overall diameter of 595 mm. This robust construction and low current density in carbon brushes contribute to reliable industrial and manufacturing performance with minimal magnetising current and smooth linear output.

The auto-transformer provides high efficiency with no waveform distortion. Equipped with round carbon brushes for smooth operation and durability. Features centre tap in winding for buck-boost use cases. Rugged enclosed construction with low operating torque ensures longevity.
