Thyristor Based Phase/Heater Controller

  • 1-PHASE :Single Phase Heater Controller
  • 3-PHASE :Three Phase Heater Controller
  • Equipment manufacturers and maintenance engineers need a reliable, flexible approach to controlling electric-heating processes in today’s competitive, cost-conscious industrial environment
  • SCR (silicon controlled rectifier) power control offers advantages including precise control of the heating process, extended heater life, improved product quality at faster production speeds and reduced maintenance costs
  • Proper selection of an SCR power control can result in many years of reliable service
Comparing Power Control
  • A silicon controlled rectifier is a solid state switching device that can provide fast, infinitely variable proportional control of electric power an SCR can cycle as fast as 0.08 seconds on a 50 / 60-Hz power line
  • With proper selection and use, an SCR power control can cycle on and off 1,000,000,000 times without any problems
  • Unlike a mechanical relay or contactor, an SCR power control has no mechanical parts to wear out
  • Reliable solid states switching of high current loads
  • Improves heater life by minimizing thermal cycling
  • Improves control accuracy with virtually no switching hysteresis
