DC Rectifiers

United Automation manufacture a range of single and three-phase controlled and 'uncontrolled' rectifier stack assemblies. 

'Uncontrolled' means there is no controlled output, therefore no firing circuit or thyristor devices are used, just diode modules. All HDC and 3/HDC stack assemblies that are fan cooled and have thermal trips as an added safety feature.

These controlled or uncontrolled DC Rectifiers, are suitable for various loads such as Electroplating, Cathode Protection, Electrophoretic Painting, Battery Charging and DC Motor Controls  

Features of both Controlled & Uncontrolled Rectifiers:

  • 15 to 750A DC Single and Three-Phase applications
  • Isolated modules used on standard range
  • Fan cooled and thermal trips fitted 150A
  • Various current ratings available
  • Optional fitted HS fuse.
