SCR Rectifiers

SCR rectifiers, also known as Silicon Controlled Rectifiers or Thyristor Rectifiers, are a cornerstone in the metal finishing industry due to their durability and long-lasting performance. These rectifiers are specifically engineered to handle high power outputs, making them ideal for demanding applications that require precise control over electrical current. Although typically larger than switchmode rectifiers, SCR rectifiers offer unmatched reliability, making them a preferred choice for industrial applications where longevity and consistency are paramount.

As a distributor of top-quality SCR rectifiers, we provide access to a wide range of products from leading manufacturers. Our rectifiers can be customized to meet your exact specifications, ensuring optimal performance in your specific application.

When selecting an SCR rectifier, consider the following factors to ensure it meets the needs of your specific metal finishing process:

  • Power Ratings: SCR rectifiers are available with power ratings up to 600 Volts and 100,000 Amps, providing the capability to handle a wide range of industrial requirements.
  • Cooling Options: Depending on your operational environment, choose between air-cooled, water-cooled, or oil-cooled rectifiers to maintain optimal operating temperatures.
  • Interface Options: Select between digital or analog remote interfaces to integrate seamlessly with your existing control systems.
  • Custom Enclosures: For specialized environments or applications, custom enclosures can be designed to protect the rectifier from harsh conditions and ensure safe operation.
  • Additional Features: Enhance your rectifier with options such as polarity reversal, pulse operation, ripple correction, ramping, and timers to meet the precise needs of your process.
