Dydac Controls Thyristor SCR Power Controllers some typical applications :

  • Large tank heating and mechanical relay replacement.
  • Thermoforming, textiles, industrial furnaces and ovens, extruders, kilns, chemical process heating, fast water heat.
  • Paper and pulp drying, packaging machines, pharmaceutical processes, infrared ovens and dryers.
  • High-temperature ovens and furnaces, kilns, glass, ceramics & hightemperature alloys.
  • High-speed paper and ink dryers, high temperature IR heating, high temperature materials processing.
  • Primary of transformer-coupled loads.
  • Phase angle proportional control. No temperature or power cycling
  • I2T Rectifier fuses standard
  • Isolated SCR's
  • Integrated thermal/mechanical design saves panel space
  • Voltage protection - MOV capacitance
  • 10 to 400 Ampere current ratings. Other Ratings Over 400 Amps Possible.
  • Easy to install, test, service
  • The Dydac Thyristor Power Controller is a heavy duty, fully Digital or Analog three phase power control unit for controlling the voltage applied to loads such as heating elements, thus, allowing temperature control while eliminating contactor switching and over/under heating. The first in a series of Digital or Analog Thyristor ( SCR ) Power Controllers incorporating protection functions.
