Phonovox - Model AT-23 Series - Three Phase Autotransformers for Voltage Regulation
FromPhonovox, S.A.
The AT-23 Series Three Phase Autotransformers, manufactured by Phonovox, are designed to optimize voltage regulation in three-phase networks. These autotransformers efficiently adjust mains voltage levels, either raising or lowering them, to meet the specific power requirements of associated equipment. This ensures optimal performance and reliability within industrial and commercial settings. Designed to operate at 415/220 V AC, these devices can be customized for other voltage configurations based on customer specifications. Their reversible design offers flexibility in a wide range of applications. As a key component in electrical installations, these autotransformers support consistent voltage transformation, thereby enabling improved operational stability and efficiency for various electrical systems.Most popular related searches
