Viconics’ R820 SCR power controller has been designed for safe and reliable control of electric heat loads. By offering a competitive price, the use of SCR’s is no longer an expensive proposition as was the case just a few years ago. As a result, this broad line of products is used by most major North American duct heater manufacturers.
Input signal can be provided by DDC panel or Viconics’ own T920 or C1025 thermostat.
