♦ Variable transformer is also known as voltage regulator, autotransformer, mainly used in the need for flexible voltage adjustment occasions, to provide variable output voltage, when the input voltage changes, the user can be manually or automatically adjusted according to the demand for adjustable range of different output voltage values.
♦ Applications: Suitable for scenarios that require frequent voltage changes, such as laboratory testing, equipment calibration, motor speed control, etc.
♦ Typical users: Scientific researchers, engineers, industrial control technicians, etc.
