Carroll & Meynell Variac 5 Output 1 Phase 3.3 kVA Panel Mount 240 V MVT3.3k/12A-1

Carroll & Meynell MVT3.3k/12A-1 variac is a precision variable autotransformer engineered for controlling alternating current voltages in single-phase electrical systems. Rated for 3.3 kVA power and a primary voltage of 240 V, it features five outputs that allow versatile voltage regulation for laboratory, industrial, manufacturing, and power supply distribution applications.

This variac integrates a high-quality round carbon brush rotating arm that adjusts the output voltage smoothly and efficiently. The brush design ensures longer life and resistance to breakage compared to conventional rectangular designs. Operating at frequencies between 50 Hz and 60 Hz, this unit provides stable and noise-free voltage adjustment with low magnetizing current and excellent regulation.

The open frame construction and panel mount type allow for easy installation and maintenance, while the robust build offers durability under industrial usage. It has an overall length and width of 178 mm, a diameter of 205 mm, and weighs 18 kg, balancing compactness with stability.

The knob rotates clockwise for intuitive voltage tuning, and the unit includes silver-plated commutator surfaces to reduce wear and enhance performance. The M4 dowel termination type provides reliable electrical connections suitable for various wiring setups. Additionally, the center tapped winding supports buck-boost applications, enabling flexible voltage adjustment strategies.

Its construction ensures negligible waveform distortion and a smooth, linear output which is essential for sensitive electronic equipment, testing setups, and controlled power distribution scenarios. Suitable for industrial, laboratory, HVAC, and commercial electrical uses, the Carroll & Meynell MVT3.3k/12A-1 is a versatile component for dynamic voltage control requirements.
