Laboratory autotransformers (LATs) are devices for smooth regulation of voltage in one and three phase mains of alternative current.

Laboratory autotransformers are applied for setting and testing industrial and household electric equipment, for manual regulation of output voltage in a wide range for household and industrial need and for testing of various devices.

What is LAT?

LATs are devices with mechanical regulation of output voltage in fairly wide ranges. Voltage regulation is carried out by means of moving load connection contact along autotransformer’s coil by turning regulator knob. Autotransformer has regulation knob with voltages scale and voltmeter which lets to precisely define output voltage value.
