Metal Finishing Equipment


A rectifier takes the incoming utility voltage and with a transformer lowers it to the voltage necessary for plating, anodizing, and electro-cleaning.  The rectifier changes alternating current (AC) to direct current (DC).  AC is the flow of an electric charge that periodically changes direction.  DC is the flow of an electric charge in only one direction. Plating, anodizing and electro-cleaning are only possible with DC.

Switch-mode power supplies (SMPS) provide the following advantages over traditional silicon-controlled rectifiers (SCRs):

  • Smaller – Take Up Less Floor Space
  • Modular – Quick Replacement if Failure Occurs
  • Efficient – No Ripple Throughout the Power Range
  • Expandable – Easily Increase Power by Adding Modules in Parallel


Switchmode Advantages Include:

  • High efficiency
  • Air or Water Cooled
  • Power factor up to 99 %
  • Ripple < 1 … 3 %
  • Constant voltage and current control
  • High control accuracy 1/2 19“–19“ plug-in or module
  • Fan speed control
  • Integrated EMC filter
  • Duty factor 100 % (24/7)
  • Analog interface: 0–10 V (except MSA 0025, 0050)

Switchmode Rectifier Options Include:

  • Pulse operation
  • Polarity reversal function
  • Ramping function
  • Ampere-hour meter
  • Digital interface: Modbus, Profibus, Ethernet
