Carroll & Meynell 3 Phase Auto-Transformer 9.9 kVA 415 V Manual Operation MVT9.9k/12A-3E

Carroll & Meynell MVT9.9k/12A-3E is a 3 phase auto-transformer designed for manual operation at a power rating of 9.9 kVA and a primary voltage of 415 V. The enclosed construction and free stand mounting provide a robust and dependable unit ideal for industrial and electrical applications requiring AC voltage adjustment.

The primary function is to vary and control AC voltages through a manual rotating arm and carbon brush system on a winding commutator, ensuring smooth and continuous voltage changes. The three variacs are connected in a star vector configuration on a common shaft, providing balanced output phases with matched brush arms.

Featuring high efficiency with no waveform distortion and excellent regulation, this auto-transformer includes a center tap in the winding suitable for buck-boost applications. It operates at low magnetising current and torque, which improves efficiency and reduces wear on the components.

Physical specifications include a length of 285 mm, a width of 280 mm, a depth of 630 mm, and a diameter of 630 mm. The device supports operation within 50 to 60 Hz frequencies and uses clamp termination type. Its construction is enclosed for safety and durability with no specific standards approval.

The auto-transformer is equipped with screw terminals, a knob, and a dial to facilitate easy and precise voltage adjustments on site. Carbon brushes are round and silver-plated commutators ensure smooth operation with long service life and low current density, reducing maintenance needs.

Applications span across industrial manufacturing, laboratory testing, HVAC controls, and electrical distribution systems where reliable and adjustable AC voltage is essential. This product is a valuable addition to any setup needing variable voltage control with high efficiency and durability.
