Three-phase reversible autotransformer 40kVA with metal box, allows the adaptation ofvoltage from 230Vac three-phase to 400Vac three-phase or 400Vac three-phase to 230Vac three-phase. It also generates neutral.
It allows you to adapt the voltage in machinery, motors, pumps, etc., in an economical way.
Three-phase autotransformer for voltage change, dry type, reversible, capable of generating neutral while transforming the voltage value. They are indicated when it is required to adapt the voltage in an economical way, without galvanic separation. Its usual field of application is the adaptation of voltages in machines, pumps, motors, etc. They are supplied in a metal box that provides an IP-23 degree of insulation, connection through terminals.
Manufactured with low-loss magnetic sheet and copper wire windings, providing high performance.
The transformer is supplied without any type of overload protection, its installation is mandatory to avoid overloading the transformer.
The power and current indicated are apparent, the active current provided by the transformer will depend on the power factor of the connected load.Material for professional use, install in compliance with the regulations in force at the installation site.
