Carroll & Meynell Variac 5 Output 1 Phase 1.4 kVA 240 V Panel Mount Open Frame MVT1.4k/5A-1

The Carroll & Meynell MVT1.4k/5A-1 Variac is a rugged, high-performance variable autotransformer designed for industrial, laboratory, and commercial power control applications. With an output capability of up to 1.4 kVA and five independent outputs, this autotransformer allows for stepless control of AC voltage, making it ideal for test benches, calibration setups, and voltage regulation tasks.

This device operates on 240 V single phase input and provides a variable AC output. Its panel mount design enables seamless integration into electrical cabinets or control panels, supporting flexible installation in factory, laboratory, and workshop environments.

Key technical features include a robust open frame construction for durability and increased heat dissipation, along with a round carbon brush system. The round carbon brush is engineered to ride imperfections on the commutator, delivering smoother voltage adjustment and lasting the lifetime of the unit. This design offers lower current density, reduces operating torque, and is less prone to wear and breakage compared to standard rectangular brushes.

Users benefit from low magnetizing current, excellent regulation, and no waveform distortion. The knob rotates clockwise for precise voltage control, and screw terminals along with M4 dowel termination ensure reliable and secure electrical connections. The device features a centre tap winding for buck - boost applications, supporting diverse voltage control needs.

The MVT1.4k/5A-1 provides continuously variable AC output voltage, making it an essential tool in laboratory testing, equipment calibration, manufacturing quality control, and industrial power management. Its high efficiency and overload capacity ensure consistent and stable performance even under demanding conditions.

The transformer measures 176 mm in length and width, with a diameter of 170 mm. It weighs 11 kg and supports frequencies from 50 Hz up to 60 Hz. Suitable for settings where precise voltage regulation is critical, including research, education, industrial automation, and electronic manufacturing.
