Carroll & Meynell Auto-Transformer 3 Phase 14.7 kVA 415 V Manual Operation MVT14.7k/18A-3E

Carroll & Meynell MVT14.7k/18A-3E is a 3-phase auto-transformer designed to provide variable AC voltage output with a power rating of 14.7 kVA and primary voltage of 415 V. This manual operation transformer is enclosed for enhanced safety and robustness in demanding industrial environments.

The transformer consists of three single-phase variacs mounted on a common shaft connected in a star vector configuration, allowing seamless voltage variation via a rotating arm and carbon brush that rolls around the winding commutator. The use of round carbon brushes ensures smoother operation and longer brush life by compensating for surface imperfections.

This model features an efficient design with silver-plated commutators that provide excellent regulation, low current density in the brushes, low magnetising current, and negligible waveform distortion. The enclosure and free-stand mount type facilitate easier installation in industrial, laboratory, and manufacturing power systems requiring controlled voltage adjustments.

Operating frequency range is from 50 Hz to 60 Hz, and it supports 3-phase electrical supply. The compact dimensions (Diameter: 690 mm, Length: 285 mm, Width: 280 mm, Depth: 690 mm) make this product suitable for integration into various equipment setups without excessive space requirements.

The product is supplied with screw terminals, a knob, and a dial allowing for reliable, smooth, and precise output voltage control. Ideal applications include voltage regulation for testing, manufacturing, and laboratory settings requiring consistent and adjustable AC voltage performance.

This auto-transformer delivers high efficiency with minimal waveform distortion and excellent voltage regulation. The robust construction ensures low operating torque and long-lasting performance. Designed for continuous variable alternating current output voltage control.

The round carbon brushes ensure low maintenance by providing longer service life and smooth operation. Screw terminals and user-friendly controls enable safe and accurate operation.

This Carroll & Meynell Auto-Transformer is a reliable component for electrical and industrial systems necessitating precise voltage variation and stable performance. Explore more transformers and power supply components in the Electronics & Electricals category at EnvMart.
