ZERO-CROSS SCR (CCS)

Description

When coupled with a time proportioning control, they operate in a series of full ON-OFF cycles known as time proportioning burst firing. The time proportional control accepts many control output signals and converts them into a time proportional signal determining the amount of full ON and full OFF cycles. A smooth power output to the load is therefore produced and the temperature, stabilized.

An SCR power switch differs from other switches in its fast action. Indeed, while a contactor may cycle 3 times per minute, our SCR may do it approximately once per second. This fast SCR cycle time results in a final temperature closer to the desired set point and therefore reduces energy costs.

Unlike traditional mechanical control, the SCR modulates small increments of power to the load, and eliminates the overshoot and undershoot associated with mechanical control.

How is work?

ADVANTAGES

  • Modulates the power nearest to the demand and reduces energy costs and power consumption
  • Keeps the temperature closer to the desired set point for maximum comfort
  • Higher precision, superior than contactors
  • Fast adjustment and installation
  • Zero-crossing operation and silent arcless switching
  • Cycles once per second; very fast and quiet
  • No maintenance necessary, due to less mechanical parts failure
  • Life expectation higher than 1 000 000 000 operations
  • Does not create RFI (radio frequency interference) and will not affect sensitive electronic equipment
  • Epoxy thermally protected for humidity, overheat or contaminated environment protection
  • Protected from line voltage transients and more reliable in a variety of applications
