A control transformer is primarily used in AC circuits with a frequency of 50Hz (or 60Hz) and a voltage of 1000V or below. It can operate continuously and long-term under rated load. It is typically used in machine tools and mechanical equipment as the power source for control lighting and indicator lights.
A control transformer is a type of small dry-type transformer. It is commonly used as a power source for local lighting, signal lights, or indicator lights, and as a power source for control circuits in electrical equipment.
