Control Transformer Working & Specification

Control transformers are used in electrical circuits, electronics that require constant voltage with low power rating. Control transformers are developed in compliance with the norms of the industry.

Control transformers are integrated with the high quality insulating materials, which is mainly used for insulating electrically layer to layer winding, turn to turn winding and primary to secondary winding. These are tested in our international standard lab and then we export it to various countries across the globe.

Working :
Control Transformer allows 120V — or near 120V — control power from a wide variety of available source voltages. Broad voltage coverage allows the MultiTap Universal Control Transformer to meet a wide variety of applications regardless of the available voltage supply level. So you won’t need to know the available supply voltage in order to select the best transformer solution to meet your application needs. In many applications, details such as the available supply voltage may be difficult to obtain and can often delay a project due to the lack of information. When using the MultiTap Universal Control Transformer, you only need to know the size requirements of the application. For designers working on export projects, this feature can be quite valuable. MultiTap Universal Control Transformer units are available in sizes ranging from 50 through 3000 VA, and Square D stocks 50, 100, 150, 250, 350 and 500 VA versions.
