The Phase Angle controls provide smooth proportional output from 0 to 100%.

Designed to offer low cost high quality SCR phase control, this series offers variable voltage outputs for many applications.

It controls load current from 15A to 1000A, at line voltage from 120 to 600 Vac

How is work?


  • 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
  • Eliminates thermal shock
  • Cycles 1/16 second; very fast and quiet
  • No maintenance necessary, due to less mechanical parts failure
  • Life expectation higher than 1 000 000 000 operations
  • Low harmonics (THD)
  • Epoxy thermally protected for humidity, overheat or contaminated environment protection
  • Protected from line voltage transients and more reliable in a variety of applications
