The 4230 Series of SCR Power Control Panels offers convenient, economical control of resistive loads and capabilities beyond the smaller, more compact 4530 series. An additional 46 Standard Options increase the application flexibility of the 4230 Series. These pre-engineered, pre-wired panels require only sensor, load and power supply connections - and totally eliminate the need to design your panel, specify and purchase separate components, and assemble them into a functioning power control system.

SCR power control efficiently and accurately proportions power to the resistive heating load. Unlike traditional contactor control, SCR’s deliver:

  • Reduced Power Cost
  • Extended Heater Life
  • Less Maintenance
  • Improved Process Products
  • Stable Process Temperature

Custom Panel Capability In addition to the pre-engineered and fieldproven standard control panels presented in this catalog, Chromalox has over 60 years of custom power control systems expertise. Working with world-scale engineering firms, military shipboard systems and the most demanding research institutes, Chromalox has encountered and conquered the challenges of even the most specialized requirements. This experience translates to efficient, economical solutions for virtually any heating and power control application.
