Rectifier Transformer Product Details:


Rectifier transformers are combined with a diode or thyristor rectifier. The applications range from very large aluminum electrolysis to various small and medium size operations. The transformers may have a built-in or separate voltage regulation unit for direct output regulation of diode rectifiers, and correspondingly a power factor improvement with a thyristor rectifier.


CTSS is renowned and appreciated by its reliable products performance and integrated services.
