SCR Assemblies

Single and three phase rectifier and SCR assemblies incorporate all of the control mechanisms that customers often place throughout a panel into one compact assembly. The benefits of SCR assemblies include:

  • Saving valuable design and production time
  • Saving large amounts of space
  • decreases the cost of production for our customers
